[jsr-314-open] Metadata complete jar files
by Andy Schwartz
Gang -
Section 11.5.1 of the spec defines the following annotation scanning
behavior:
> Requirements for scanning of classes for annotations
> * If the <faces-config> element in the WEB-INF/faces-config.xml file
> contains metadata-complete attribute whose value is “true”, the
> implementation must not perform annotation scanning on any classes
> except for those classes provided by the implementation itself.
> Otherwise, continue as follows.
> * If the runtime discovers a conflict between an entry in the
> Application Configuration Resources and an annotation, the entry in
> the Application Configuration Resources takes precedence.
> * All classes in WEB-INF/classes must be scanned.
> * For every jar in the application's WEB-INF/lib directory, if the jar
> contains a “META-INF/faces-config.xml” file or a file that matches the
> regular expression “.*\.faces-config.xml” (even an empty one), all
> classes in that jar must be scanned.
Since application developers have the ability to disable annotation
scanning at a global level, this means that any component set that wants
to support this mode would need to provide a metadata complete
faces-config.xml file. I don't think this is a hardship for most
component vendors, since presumably component vendors are going to want
to provide design-time metadata (eg. JSR-276 metadata), which, for the
moment, requires a faces-config.xml file anyway.
A question that came up here is whether we can tweak section 11.5.1 to
accommodate metadata complete jar files. That is, can we specify that
any jar that contains a faces-config.xml with a metadata-complete="true"
attribute would not be scanned? This would allow component vendors to
indicate that their jar files are metadata complete, and thus avoid the
cost of annotation scanning for the contents of the jar.
Note that while the annotation scan is typically a one time hit (during
application startup), design-time tools may end up starting/stopping JSF
repeatedly during the development process. Thus, avoiding unnecessary
scanning should provide for a more efficient development experience.
Any thoughts on whether we could/should make this change? Does anyone
know of reasons why we avoided specifying this originally?
Also - if we agree to make this change, is this small enough that we
could get this into the the next MR?

[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.

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.

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.

1. rename composite:insertFacet to composite:renderFacet
2. create composite:insertFacet that reparents the named facet from the

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.

[jsr-314-open] DRY and form with JSF 2
by Damien Gouyette
Hello,
I have a lot of forms to do and i don't understand a point
<h:outputLabel value="client's birthdate" for="birthDateField"/>
<h:inputText id="birthDateField" label="client's birthdate"/>
<h:message for="birthDateField"/>
if i don't set label on inputText, i have an error message like :
formNew:birthDate: 'a' could not be understood as a date. Example:
12/09/2009 instead of
client's birthdate : 'a' could not be understood as a date. Example:
12/09/2009
Can you reuse outputLabel value if exists ?
Just for information, this message is the french error message when i
set a dateConverter on my inputText. (little bug)

Essentially this is the opposite of the RichFaces 4 plan (I agree, the
comment that this discussion is based on is ambiguous at best). Just
like ICEFaces, we intend to build RichFaces 4.0 on top of the JSF 2
Ajax API. I've asked Jay (RichFaces project lead) to blog in detail on
this to clear up the confusion :-)
From initial discussions with Alex, my understanding is JSF 2 Ajax
will account for around 70% of what was in Ajax4JSF (which IMO just
validates how complete JSF 2 Ajax is!). The remaining 20% has not been
specified (not ready yet, or no consensus or ...), and will be built
as extensions on top of JSF 2 Ajax.

Thank you. Please take the valuable discussion of caching and resources
to a separate thread.
>From the previous discussion, I draw two alternatives, which I place on
the table for further debate.
OPTION RestrictAllowableExpressions
With this option, we modify Resource.getInputStream() to state that the
implementation must evaluate EL Expressions in resource files if and
only if the expression is simple (not compound) and starts with the
"resource" implicit object. Handling of any other kinds of EL
Expressions requires decorating the ResourceHandler.
OPTION DefaultToOptOut
With this option, we modify Resource.getInputstream() to state that EL
evaluation in Resource files is disabled by default. For simplicity, I
suggest the user convey their intention at a per-application granularity
using a context-param. If the user does decide to opt-in, all EL
Expressions in all resources are evaluated every time the resource is
served. Resource.getInputStream() will include non-normative text
alerting the user to possible scope complications.
I prefer RestrictAllowableExpressions because decorating the
ResourceHandler is an easy way to allow more powerful behavior.
ACTION: Please voice your opinion by 1700 EDT Monday 28 September 2009.

[jsr-314-open] Evaluating EL in resource files
by Ed Burns
Greetings EG,
We have two problems here. First, let me restate the intent of the
feature.
FEATURE SHORT DESCRIPTION:
==========================
Let JSF2 resources refer to other resources in a way that the browser
can make GET requests to load them via the ResourceHandler.
RATIONALE for FEATURE:
======================
CSS files may refer to other files using the following syntax
url( some URL )
The url() element may appear in several places in a CSS file, most
commonly to the right of @import, as in
@import url(layout.css)
@import url(typography.css)
@import url(colorAndMedia.css)
Unfortunately, this doesn't "just work" when the CSS file in question is
in a JSF resource library, for obvious reasons.
The solution we chose was to allow EL expressions in CSS files. That
way, you could say this in your css file:
@import url(#{resource['this:layout.css']})
@import url(#{resource['this:typography.css']})
@import url(#{resource['this:colorAndMedia.css']})
and when the file actually gets served up it would look like:
@import url(/jsf-ezcomp02/javax.faces.resource/layout.css.jsf?ln=ezcomp);
@import url(/jsf-ezcomp02/javax.faces.resource/typography.css.jsf?ln=ezcomp);
@import url(/jsf-ezcomp02/javax.faces.resource/colorAndMedia.css.jsf?ln=ezcomp);
PROBLEM 1. This behavior should have been specified in the javadocs for
Resource.getInputStream(). I've added this to the ChangeLog.
PROBLEM 2. JavaScript resources have the same problem; they can refer
to other javascript files and the browser needs to know how to fetch
them. We employed the same solution: put EL in there and it gets
evaluated on the way out.
Unfortunately, the prototype JavaScript library uses #{} to mean
something important.
SUGGESTED SOLUTION to PROBLEM 2.
Let's assume PROBLEM 1 didn't exist. I suggest we modify the spec for
getInputStream() to say that all resources EXCEPT JavaScript resources,
must do the EL evaluation on the way out. We need some way for users to
enable the feature for JavaScript resources because, let's face it, not
everyone uses prototype. Ryan and I suggest we adopt a protocol that
says, "if the resource name ends in '-el' we always turn on the EL
evaluation on the way out".
Thoughts?
