Long-running conversations and EntityHome

[ericjava]

EntityHome is quite a useful class. Extend it, and you can create, update, and delete entities easily.

The problem with it is that it's a POJO. I tried everything I could think of, but could not get it to exist in a long-running conversation. This limits its usefulness.

So, I created a local interface and implemented it.

The problem is that there is a remove() method in the EntityHome class, and when it becomes a SFSB, JBoss gets confused about whether remove() is the remove method, or the @Remove annotated method is the remove method. That makes it not work.

Is there a solution to this, other than to not try to make EntityHome into a SFSB?

EntityHome is conversation-scoped. It gets used in long-running conversations in seam-gen apps. So I don't think there's a need to turn it into an SFSB.

I do a wild guess that your problem could be related with mine.

I do have no problem do work with entityHome Objects in the way which is used in a semgen generated app.
But...
When i try to initialize an entityHome from a javabean, no luck.
What i am trying to do is this:

@Name("genFieldplan")
//@Scope(ScopeType.CONVERSATION)
public class GenerateFieldplanBacking {
[...]
 public void fetchEvaluation(){
 log.info("UserEvaluationId : #0",calcEvaluationId());
 evaluationHome.setEvaluationEvaluationId(calcEvaluationId());
// Evaluation evaluation = evaluationHome.getInstance();
// log.info("evaluation: #0, ID: #1",evaluation,(evaluation==null?null:evaluation.getEvaluationId()));
 }

this code is called from this page:

<h:form>
 <h:commandButton action="#{genFieldplan.fetchEvaluation}" id="search" value="Search for Evaluation" />
</h:form>
 <rich:panel >
 <f:facet name="header">Evaluation</f:facet>

 <s:decorate id="evaluationId" template="/layout/display.xhtml">
 <ui:define name="label">evaluationId</ui:define>
 #{evaluationHome.instance.evaluationId}
 </s:decorate>
[...]

What happens is this:
If no long running conversation is active, after pressing the commandbutton the evaluation is shown.

When i start a long-running-conversation(in *.page.xml for the page)
no evaluation is shown after pressing the button.

Is this what you mean?
And for others what do i make wrong? Any hints are welcomed
Ciao,

I extended my page with this code:

<s:decorate id="evaluationIdHome" template="/layout/display.xhtml">
 <ui:define name="label">Home evaluationId</ui:define>
 #{evaluationHome.evaluationEvaluationId}
 </s:decorate>

If my page starts a conversation this happens:
the home evaluationId is set correctly, but the instance id is empty.

When my page does not start a conversation, all is well as stated above.
