[JBoss Seam] - Re: Writing SeamTests with Seam 2.0.0. CR2 - What's Changed?
by bsmithjj
WEB-INF/components.xml? no - I'm trying to boot the embedded jboss ONLY from an ejb module that's part of a larger ear project. This all worked nicely in Seam 1.2.1. I say that because (as you probably know quite well by now ;-)) that I am immensely frustrated at things like <core:ejb> disappearing. I can't understand why you wouldn't think about supporting that IN ADDITION TO whatever new form of the JBoss container you want people to be able to boot and test with. As it stands now, in order to migrate our development process from Seam 1.2.1 to Seam 2.0.0, I have to figure out how to get a working jboss embedded (in addition to other things). Although traditionally, the focus of a framework evolution is to fix problems in the current version of the framework and add in new features, this current 'style of evolution' I see in Seam is one in which I am forced to move all dimensions of my development work forward simultaneously.
On the subject of maven and transitive dependencies, please do not deploy the Seam 2.0 releases to your public repository with poms that contain transitive dependencies - that's already tripped me up once because Seam 2.0.0.CR3 transitively stuck el-api.jar into my war and that already existed in the server. Transitive dependencies buy you nothing when they cause unexpected problems that take longer to fix (due to the surprise nature) than simply adding the dependencies you know you need due to good documentation. Knowing version dependencies (to me) is a good thing. Hiding versions and/or dependencies is bad.
BTW, Pete, I appreciate your discussions / interactions and patience with me ;-). In all my rants on the forum here, my frustrations tend to stem from no smooth transition being available for Seam 1.2.1 -> Seam 2.0.0 (on the issues I've posted about). I believe Seam could be a little kinder to its early adopters than it has been. Instead, I have several areas now where I need to 'start from scratch' (e.g. <core:ejb/> gone but actually worked fine ... hence this particular thread).

[JBoss Seam] - Re: Pageflow problems with back button
by jbeaken
Trying to use a ui:include but I need to generate dynamic s:links, not even sure it's possible, something like this:
Page that has the ui:include
| <ui:include src="/include/pagination.xhtml">
| <ui:param name="next" value="#{listCompaniesService.next}"/>
| <ui:param name="itemCount" value="#{listCompaniesService.itemCount}"/>
| <ui:param name="batchSize" value="#{listCompaniesService.batchSize}"/> <ui:param name="firstItem" value="#{listCompaniesService.firstItem}"/> </ui:include>
|
with include :
| <ui:composition xmlns="http://www.w3.org/1999/xhtml"
| xmlns:s="http://jboss.com/products/seam/taglib"
| xmlns:ui="http://java.sun.com/jsf/facelets"
| xmlns:f="http://java.sun.com/jsf/core"
| xmlns:h="http://java.sun.com/jsf/html">
| <!-- FIRST -->
| <s:div id="tabcontainer" rendered="#{firstItem < batchSize}">
| <s:div styleClass="pageresults" rendered="#{itemCount > 0}">
| <div class="middle_highlight">
| <h:outputText value="#{firstItem + 1} ... #{itemCount < firstItem + batchSize ? itemCount : firstItem + batchSize}"/>
| </div>
| </s:div>
| <s:div styleClass="pageresults" rendered="#{itemCount > batchSize}">
| <s:link styleClass="middle" action="#{next}" value="#{firstItem + batchSize + 1} ... #{itemCount <= firstItem + (batchSize * 2) ? itemCount : firstItem + (batchSize * 2)}"></s:link>
| </s:div>
| <s:div styleClass="pageresults" rendered="#{itemCount > (batchSize * 2)}">
| <s:link styleClass="middle" action="#{next}" value="#{firstItem + 21} ... #{itemCount <= firstItem + 30 ? itemCount : firstItem + batchSize + (batchSize * 2)}"></s:link>
| </s:div>
| </s:div>
| ....
|
the dynamic s:link is found at :
<s:link styleClass="middle" action="#{next}" ...
In my head I think it won't be possible, unless maybe constructing a <a href manually, but anyone done it?

[JBoss Seam] - Custom ObjectConverter for selectItems - howto El in convert
by gonzalad
Hello,
I'm coding a generic object converter which will work for non jpa backends (i.e. jca, jdbc, ...) - similar to the one in http://www.jboss.com/index.html?module=bb&op=viewtopic&t=122149&postdays=....
But stateless.
The converter is used for selectItems - Here is a sample jsf code to display a country selectBox (sx:convertObject) :
<h:selectOneMenu id="country"
| value="#{client.adress.country}" styleClass="selectBox">
| <sx:convertObject var="value" asStringEl="value.id"/>
| <s:selectItems value="#{countryManager.allCountries}"
| var="country" label="#{country.libelle}"
| noSelectionLabel="Please Select..." />
| </h:selectOneMenu>
How does it work ?
On render, it applies the el #{value.id} on every object of selectItems (so call country.getId for every country).
On submit, it applies once more this el on all selectItems objects until retrieving the selected string value.
Here's my questions :
1. I would lik to use a real EL in asStringEl attribute.
How can I achieve it in a converter ?
I've tried setting asStringEl="#{value.id}", but facelets interprets it *before* my converter - and I retrieve value "" in my converter.
2. Does this approach appears fine or is there a better one (it's my first Jsf converter - so quite a newbie...).
Sorry for this long mail and thank you very much for you help.
Here's my converter code :
@Name("com.natixis.sphinx.jsf.component.objectConverter")
| @org.jboss.seam.annotations.jsf.Converter
| @Scope(ScopeType.STATELESS)
| @Install(precedence=Install.FRAMEWORK)
| public class ObjectConverter implements Converter, Serializable {
