[jsr-314-open] ADMIN: Final list of issues for JSF 2.0 and actions for each
by Ed Burns
This is the final list of issues for JSF 2.0. No other issues will be
considered for 2.0.
I do not think content of any of these issues, nor their quantity,
warrant another Proposed Final Draft, but I will of course produce an
Editor's Draft for the public on jsr-314-open to review.
I will send another email with the dates for the remainder of JSR-314.
Any further discussion on any topic sent to this list will be rolled
into the next release of the spec.
SECTION: List of EG Members from whom I have obtained explicit buy-in
I have obtained explicit buy in for this list in its present state from
the following EG members.
Pete Muir Status: DONE, but need final official answer from JBoss. Promised by 1800 EDT 20090415.
Andy Schwartz 617 794 7974 Status: DONE Spoke with him 1319 20090415
Kito Mann 917 848 3359 Status: DONE Spoke with him 1600 20090415
Martin Marinschek +43 699 1805 3906 Status: DONE Spoke with him at 1400 EDT 20090415
Ken Paulsen x42083 Status DONE Spoke with him 1403 20090415
Alexandr Smirnov DONE IRC chat with him 16:00 20090415
SECTION: Issue sums
Number of issues remaining: 30
I've broken down the issues into two groups, bigger and smaller. I
assert that we do not need to do a PFD2 because none of the issues are
so big as to warrant such an action.
Bigger issues:
Number of bigger issues: 16
deferred: 5
will fix: 10
pushed to EG member requesting the issue: 1
Smaller issues:
Number of smaller issues: 14
deferred: 1
will fix: 13
SECTION: Bigger issues
PM> ISSUE: 1) Fully stateless views. This is a performance optimization
PM> which is ideal for the use case of pages which are output-only (no
PM> form). This is moderately complex to get right, and a blocker in our
PM> opinion. This also has the support of Apache.
We see two aspects to consider.
a. Marking specific views in an app as stateless. Putting a
transient="true" attribute on <f:view> doesn't work here because the
template page with <f:view> can be shared across pages.
There are several options we could try but none of them are feasible at
this point in time.
b. If the Form Renderer never calls StateManager.writeState(), and the
ViewHandler is aware of this fact, then you have a stateless view.
Therefore, statelessness is an implementation detail. Adam Winer
provided this idea, which we implement in Mojarra.
ACTION: Defer to a later release.
EB> Pete agrees to defer, but Gavin does not.
EB> Andy agrees to defer.
EB> Ken agrees to defer.
EB> Martin agrees to defer.
EB> Kito agrees to defer
EB> Alexandr, agrees to defer, but is unhappy about it.
PM> ISSUE: 3) Better handling of whitespace in facelets. Currently
PM> whitespace in view sources can get "eaten" and you have to resort to
PM> tricks like to add space. I would put this as a critical and
PM> the (spec) complexity as low (simply switch it on/off).
ACTION: Defer to a later release.
EB> Pete says, "70 - yes, defering that is fine"
EB> Andy is ok for deferring this
EB> Ken is ok to defer.
EB> Martin agrees to defer. Not a spec issue.
EB> Kito agrees to defer.
EB> Alexandr, agrees to defer
PM> ISSUE: 2) First class support for page actions. This allows a more
PM> action orientated approach (Struts style) approach to page
PM> authoring, where some arbirtrary method can be run when the page is
PM> accessed. Use cases include security (redirect to another page if
PM> the user isn't logged in for example). JSF2 currently includes
PM> "second class" support - it's possible to do this stuff, but not in
PM> simple fashion. As the design for this has already been done, and
PM> reviewed/approved by the EG, the complexity is low. I would put this
PM> as a blocker. It also has the support of Oracle.
Pete, when we had the discussion regarding View Parameters, we decided
to defer Page Actions to a later release. We will not reverse that
decision.
ACTION: Defer to a later release.
EB> Pete says "I am happy for this to slip, given you can do a
EB> workaround with events. l know Dan is unhappy with the current
EB> state. On this one, Gavin was wavering, and would probably be happy
EB> to slip it".
EB> Andy can accept deferral for this
EB> Ken says, "Events should be able to accommodate this use case until
EB> we have a chance to improve the user-experience in a later release.
EB> I think we should defer this.
EB> Martin says ok to defer. But Ed and Martin agree that we should
EB> have a {Pre,Post}BuildViewEvent that is published appropriately.
EB> Kito agrees to defer.
EB> Alexandr, agrees to defer
PM> ISSUE: 5) make behaviour of new components more consistent -
PM> currently f:validateBean (JSR-303 support) / f:ajax use different
PM> strategies to mark areas of the areas of the page to enable. Align
PM> these. This is a blocker (once it is written in stone we can't go
PM> back and fix it) and complexity low (the EG has agreed on the
PM> correct design, so the language needs tweaking in the spec and
PM> javadoc). This has the support of Oracle.
ACTION: If the EG agrees that the default validator setup currently hard
coded into UIInput.encodeEnd() can be moved into
Application.createComponent(), this can be done.
EB> Pete agrees with the plan on this.
EB> Andy agrees with the plan on this.
EB> Ken agrees with the plan on this.
EB> Martin agrees with the plan on this.
EB> Kito agrees with the plan on this.
EB> Alexandr agrees with the plan, but thinks the tag handler is a
EB> better place to imbue the component with the default validator.
PM> ISSUE: 7) Allow multiple error messages for a component to be
PM> displayed - especially useful for JSR-303 support. This is
PM> complexity low, and priority minor (easy for an addon to fix).
ACTION: Pete, please submit a diff patch modifying the following files:
standard-html-renderkit-base.xml jsf-api/doc/standard-html-renderkit-base.xml
message-message-props.xml jsf-api/doc/message-message-props.xml
to specify the change, and the necessary implementation changes for this
feature.
For to the patch to be accepted at this VERY late date it must meet the
following requirements. Because of the late timing of this feature
request we will be unable to accept the feature if the patch doesn't
meet all of the following requirements.
* All existing automated tests still run successfully after applying the patch.
* The spec wording in the patch requires no grammatical or formatting
changes.
* The patch is sent to the EG list no later than 23:59 EDT Wednesday
20090415.
RL> ISSUE: 2. View ID Derivation Fix
RL> (java.net Issue 1002)
RL> Status: Ed had a fix - push back from Ken Paulsen on the fix;
ACTION: Because this breaks the V3 Admin GUI, it must be fixed for 2.0
=> edburns fix by Thursday 20090316 17:00 EDT.
RL> ISSUE: 3. Client Behavior in Composite Components
RL> (patch from Exadel)
RL> Status: Patch 1 checked in; Patch 2 checked in;
RL> Javadocs / prose updates need to be made.
ACTION: Fix checked in to revision 6952, will review spec implications
RL> ISSUE: 4. Bean Validation Bug Fixes
RL> (java.net issue 1058)
RL> Status: Checked in; Needs discussion; Javadocs, prose updates
ACTION: Will review docs, RELEASE_PENDING. Make sure spec for
CompositeComponent Attributes ELResolver mentions this, 5.6.2.2
JD> ISSUE: Impl 1071: UIData.visitTree()
ACTION: Will Fix. fully specify
JD> ISSUE: Impl 1072: Facelet Meta* Javadocs not cleanroom implementable
ACTION: Will fix.
EG> ISSUE: JavaScript disabled support [Was: Outcome of JSFDays
EG> discussions]
ACTION: This can easily be doable in a later release. Considering the
late date of this request we need to defer it.
EB> Pete is ok with deferring this.
EB> Andy is ok with deferring this.
EB> Ken is ok to defer.
EB> Martin is ok with defer
EB> Kito agrees to defer.

EB> Andy's ok with deferring this.
EB> Ken is ok to defer this.
EB> Martin is ok to defer this.
EB> Kito ok to defer this.
EB> Alexandr, agrees to defer
EG> ISSUE: remove target attr from h:outputStylesheet (was:
EG> h:outputStylesheetdocs need to be updated)
ACTION: Will fix this
EG> ISSUE: #{compositeComponent.attrs....} verbosity
ACTION: Change "compositeComponent" to be "cc". Implementations may
provide a context-param that allows renaming the implicit object name to
an arbitrary value for the case where an app happens to have a
managed-bean named cc.
EB> Pete says he won't object to this solution.
EB> Andy is ok with this action
EB> Ken says, "I like 'cc' better to solve the verbosity issue. I
EB> recommend deferring on the renaming via context-param for now -- but
EB> would not object to it making the release if others feel strongly
EB> that it needs to be done now."
EB> Martin is ok with this solution.
EB> Kito is ok with this solution.
EB> Alexandr is ok to defer.
EG> ISSUE: composite insert children
ACTION: 2 days. Take the following steps
EB> Pete is ok with this action.
EB> Andy is ok with this action.
Ken says,
KP> I am very nervous about the reparenting (insert*) commands. If 2
KP> composite:insertFacet/Children tags are used in the same composite
KP> component, it will likely fail. Is that acceptable?
EB> We will specify that if multiple <composite:insertFacet> elements
EB> exist with the same name in the <composite:implementation> section,
EB> the "last one wins".
EB> We will specify that if multiple <composite:insertChildren> elements
EB> exist in the <composite:implementation> section the facelet layer
EB> must throw a FaceletException.
KP> If the component inserted has code which does: getParent(), they'll
KP> be exposed to the internal workings of a composite component (which
KP> they shouldn't know exists).
Yes, you are correct, but I feel this is sufficiently corner case to
ignore.
KP> I would prefer render* in most cases. In cases where this isn't
KP> possible (implementing a facet inside a composite component),
KP> perhaps we can do a proxy component which can be added to the inner
KP> facet and delegate rendering to the page-facet? I think there will
KP> be problems with this implementation. If I am wrong, then I do not
KP> object to this going in -- otherwise, I think it should be deferred.
EB> Martin is ok with this action.
EB> Alexandr is ok with this action.
1. rename composite:insertFacet to composite:renderFacet
2. create composite:insertFacet that reparents the named facet from the
top level component to be a facet child of the parent tag in the
composite:implementation section in which the composite:insertFacet
resides.
3. delete composite:renderUsingPageChildren
4. create composite:insertChildren that reparents the children from the
top level component to the parent of tag in the composite:implementation
section in which the composite:insertChildren resides.
5. For composite:insert{Facet,Children} support nested composite
components.
=> edburns take this to Bill and see what he thinks, if we need to do a
PFD2.
SECTION: Smaller issues
PM> ISSUE: 6) Better support for timezones. Currently only one of two
PM> timezones can be used - default or system. The user may well be in
PM> some other timezone entirely, so make the timezone used
PM> configurable. This is a critical issue, and the complexity is medium
PM> (but we have a full proposal for this waiting in the wings that
PM> didn't make it due to time constraints)
If this was a truly critical issue, it would have been brought up a long
time ago, not after the PFD has been published. Furthermore, this is a
platform level thing. I direct you to your JSR-316 EG rep for this feature.
ACTION: Defer to later release.
EB> Pete is ok with deferring this.
EB> Andy is ok with deferring this.
EB> Ken says defer.
EB> Martin ok to defer.
EB> Kito ok to defer.
EB> Alexandr is ok to defer
RL> ISSUE: 2. 11.4.7 - Absolute ordering. I think if a document name
RL> is explicitly referenced but not present, an exception should be
RL> thrown.
ACTION: We'll log a message in this case.
EB> Pete's ok with this action.
EB> Andy's ok with this action.
EB> Ken's ok with this action.
EB> Martin is ok with this action.
EB> Kito is ok with this action
EB> Alexandr states, "if related document was not present, it is
critical error, therefore Exception should be thrown." Given the
prevailing opinion, we'll stick with logging.
RL> ISSUE: 3. FacesRenderKit annotation hasn't existed from some time
RL> now.
ACTION: Remove this from the spec.
RL> ISSUE: 4. Javadocs for EditableValueHolder.addValidator() and
RL> ValueHolder.setConverter() mention ResourceDependency annotation
RL> processing. This documentation should be moved to
RL> Application.createConverter() and Application.createValidator().
ACTION: Will fix this in the spec.
RL> ISSUE: 5. 3.1.11 mentions that the AttributesMap, if the current
RL> component is composite, must eval any ValueExpressions stored in the
RL> Map. This is incorrect. This logic is handled by the
RL> CompositeComponentAttributesELResolver
ACTION: Will fix in the spec.
RL> ISSUE: 6. Preface references META-INF/managed-beans.xml. Support
RL> for this file is no longer required.
ACTION: Will fix.
RL> ISSUE: 7. 5.6.2.2 Doesn't mention any support for the special
RL> parent keyword in #{compositeComponent} expressions.
ACTION: Will fix.
RL> ISSUE: 8. 6.1.1.15 lists Flash as a property of FacesContext. It's
RL> now a property of ExternalContext.
ACTION: Will fix.
RL> ISSUE: 9. 7.1.1 and 7.1.2 Typo in assertion marker
RL> 'defualtActionListener' and 'defualtRenderKit' There may be others.
ACTION: Will fix
RL> ISSUE: 10. 7.4.2 will need to be discussed due to the
RL> implementation of issue 1066.
ACTION: Will fix
RL> ISSUE: 11. 7.4.3 should include a navigation case example with
RL> redirect parameters.
ACTION: Will fix
RL> ISSUE: 7.5.1 and others. This may already be done, but
RL> PageDeclarationLanguage should be ViewDeclarationLanguage
ACTION: Will fix. Make sure retargetAttachedObjects and retargetMethodExpressions are on VDL, not ViewHandler.
RL> ISSUE: 1. Spec ResponseWriter methods: startCDATA endCDATA (java.net
RL> issue 1055) Status: impl done; method javadocs / prose need to be
RL> done;
ACTION: Will fix
EG> ISSUE: View and custom scoped eager managed beans?
ACTION: Will Fix. Add eager for session scoped managed beans
RL> Update 3rd bullet in 11.5.1 so that pattern for custom faces config file
names is something that ends with .faces-config.xml. This brings it in
alignment with 11.4.

[jsr-314-open] Wrapping Text with a tag - what's the correct behavior?
by Jim Driscoll
Currently, when we wrap text in tag, like h:outputText, we get output
like this in mojarra:
<h:outputText id="foo" value="value">text!</h:outputText>
gives:
text!<span id="foo">value</span>
Eww. But, AFAICT, unspec'd, and we don't want you doing that, anyway.
And it seems it's always done it this way. (And to answer, yes, I
occasionally make this mistake when I'm marking up a page - some sort of
mental defect on my part, apparently.)
But when I then put an ajax tag there, like so:
<f:ajax>
<h:outputText id="foo" value="value">text!</h:outputText>
</f:ajax>
(not valid, think of this as pseudo-tag-code)
then I get:
text!<update id="foo">[CDATA[... span ]]</update>
Which, of course, is not a valid return - the text isn't allowed in the
schema to be there.
So, I've got a few different things we can do, but my preferred solution
is to ignore the wrapped text (i.e., don't traverse the children, don't
output anything under foo) for the *ajax* case only, and leave it alone
for the full response case, since I don't want to break any existing
odd-looking code.
I'd repeat this for all components like outputText, I haven't done the
homework yet there to see which components require it.
Thoughts? I don't think we should bother spec'ing this behavior, but
you may disagree.

[jsr-314-open] remove method for UI component tree
by Dan Allen
I would like to propose that we add some way to have a server-side component
tree removed from the session in the same way that there is a @Remove method
on a stateful session bean. As you know, the component tree is only cleaned
up when it falls out of the component tree queue in the session (LRU).
However, there are times in the application when it is clear to the
developer based on a navigation event that the user is departing a page and
will not restore it in the future. I suggest that we introduce the method
remove() on UIViewRoot that removes the component tree from the session
immediately.

[jsr-314-open] JavaServer Faces Wiki Book
by Dan Allen
I've taken the liberty to create a Wiki Book for the JavaServer Faces
specification on the new jcp.org site. A wiki book is no more than an
organized collection of wiki pages...a distinct root so to speak.
http://wiki.jcp.org/wiki/index.php?structure_id=6
I began working on porting Red Hat's proposal list to the wiki, which is
currently hosted at http://seamframework.org/Documentation/JSF2 So far I can
tell you that editing pages is **really** annoying. First of all, the TWiki
syntax is nothing short of madding. I strongly recommend you disable it,
because it's utter crap, and just use plain HTML (which has worked so well
for so many years). I also found no way to disable the equally madding
FCKEditor other than disabling JavaScript on my browser. Once I had a
regular text area where I could type regular HTML, I was finally able to get
something done. However, I am still extremely annoyed by the auto-linking of
WikiWords. I cannot express how much I despise auto-linking. It makes the
source look very ugly because you contantly have to put ~np~ symbols around
words like UICommandLink (e.g., ~np~UICommandLink~/np~).
The idea of a wiki for the EG makes me very excited, but I can't say that I
am 100% committed to porting our feature list over until I can get a bit
more comfortable with its editor.
I encourage you all to give it a try by contributing some information you
feel belongs on the wiki. Maybe I'm just being impatient at the moment. Or,
perhaps we can give the maintainers some feedback so they can make it easier
to use.

[jsr-314-open] Ajax validation
by Pete Muir
Hi all,
I was chatting with Alex Smirnov this week, and he pointed out that an
essential feature needed for Ajax validation is missing from the Ajax
support in JSF 2.0.
When you are doing Ajax validation, you need an option to not update
the backing beans (in other words, skip the update model phase), so
that *if the value is valid*, then aren't saved to the model. I think
this is sufficiently important enough to go into the JSF maintenance
release. The RichFaces syntax is like:
<f:ajax updateModel="false" />
BTW, Ed, any updates on the MR?

[jsr-314-open] Default ajax triggers?
by David Geary
The pdl docs have this to say about f:ajax's event attribute: "If not
specified, the default event is determined for the component."
Does anyone know if those default events are documented anywhere? I had to
turn to the mojarra source to find out.
Thanks,
david

[jsr-314-open] Ajax: Include View State For Forms That Are Partial Render Targets
by Roger Kitain
Background:
It used to be that when processing an Ajax response on the client, all forms in the view
would get updated with the view state from the server (which had it's own set of portlet
related issues). Before the specification went final it was decided that only the
submitting form should have it's view state updated from the server.
Problem:
Consider the case where there are multiple forms in the view, and one of the forms
is a partial render target. So here, "form1" is an Ajax render target:
<h:form id="form1">
<h:commandButton value="Should be postback" id="button1"/>
</h:form>
<h:form id="form2">
<h:commandButton value="Rerender form1" id="button2">
<f:ajax render=":form1"/>
</h:commandButton>
</h:form>
In this scenario, "form1" is missing the view state identifier causing a
"non postback" when "button1" is clicked.
-----------------------
I think this could get by as an errata for the MR, as we would need to include additional
spec language.
The fix is trivial, but I wanted to run this by the rest of the group.

[jsr-314-open] required attribute for composite components
by David Geary
I'm writing the Composite Components chapter for CJSF, and I hate to say:
"Due to a bug in the reference implementation for JSF 2.0, the required
attribute for composite components doesn't work." :(
It would also be nice if we documented the repercussions for not supplying a
required attribute.
I filed a bug report on this awhile ago. It seems like some low-hanging
fruit, as far as bugs go.
Thanks,
