[jboss-user] [JBoss Seam] - Latest CVS EntityQuery troubles/doubts

[fernando_jmt]

Hi.

I've updated to latest SEAM CVS (20070602), the improvements are good. Nevertheless I have some questions/doubts:

A) The method isNextExists() always returns false. I made some debug and I found that isNextExits() method is called  before than getResultList() (I'm sure it is related with some JSF Phase behaviour), this means the value of "resultList" property will always be null. I resolved this making this change:


  | @Override
  |    @Transactional
  |    public boolean isNextExists()
  |    {
  |       return getResultList()!=null && 
  |             resultList.size() > getMaxResults();
  |    }
  | 
I'm sure you guys have a better solution...


B) Is it possible to have a EntityQuery in the SESSION scope?
I tried to do it. But it does not work (EntityManager is closed exception is thrown). I think there is some reason behind it, can you make me figure it out?


C) Can I use DataModelSelection when using EntityQuery?
What I want to have is something like:

  | <rich:dataTable value="#{userList.dataModel}" var="userItem" id="userListId"
  |                 rows="#{userList.maxResults}">
  | ....
  | <rich:column>
  |         <f:facet name="header">#{messages['Common.action']}</f:facet>
  |         <s:link value="#{messages['Common.view']}" action="#{userAction.select(userItem)}"/>
  | </rich:column>
  | ....
  | 
  | </rich:dataTable>
  | 

At this time I can use #{userAction.select(userItem)} only if I have a component which explicitly use @DataModel annotation. But it would be nice to have this out-of-the-box on entity-query. 


Thanks in advance.
