[JBoss Seam] - Latest CVS EntityQuery troubles/doubts
by 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.
