@DataModel doesn't load the first time

[james_hays]

Hey guys, I have an interesting issue with @DataModel. I don't believe I have changed anything after I had this working when I moved to Seam 1.1.6

What I have is a search page that takes some data on page a, enters an action listener, runs a query against the database and outjects the value through @DataModel to be used on page b. The values are coming back from the database and populating the instance value correctly, but my xhtml won't see the data until I hit refresh page 5.

Here's a few code snippets.

@Name("search")
@Stateless
public class SearchAction implements Search
 {
 @Logger
 private Log log;

 @PersistenceContext
 private EntityManager em;

 @Out
 @In
 ProfileRecord profileRecord;

 @DataModel
 private List<ProfileRecord> searchResults;

 @DataModelSelection("searchResults")
 private ProfileRecord currentProfileRecord;

 public String basicSearch()
 {
 log.info("Running Basic Search");
 ProfileRecord pr = new ProfileRecord();
 pr.setWaNumber(profileRecord.getWaNumber());
 pr.setProposalNumber(profileRecord.getProposalNumber());
 profileRecord = pr;
 searchResults = em.createQuery("Select pr from ProfileRecord pr where pr.waNumber LIKE :waNumber")
 .setParameter("waNumber", pr.getWaNumber() + "%")
 .getResultList();
 log.info("Profile Records Found: " + searchResults.size());
 return "/detailedSearch.seam";
 }

 <ui:define name="content">
 <div class="tabularData">
 <h:dataTable cellpadding="0" cellspacing="0" value="#{searchResults}" var="currentProfileRecord" rules="all" width="100%">
 <h:column>
 <f:facet name="header">WA #</f:facet>
 <h:outputText value="#{currentProfileRecord.waNumber}" />
 </h:column>
 <h:column>
 <f:facet name="header">SBU</f:facet>
 ???
 </h:column>

When this page loads the first time, the table with the DataModel is empty. as soon as I refresh the page, it's there. I've run the debugger and the list is populated the first time through.

Any thoughts on what might be causing this?

[james_hays]

To add a bit more clarification after working on this some more, I can't get it to work with any previous Seam builds either. It also will not populate the table after a refresh, but will populate it if I call an action that either returns null or has a void return type. I had this working at one point and it's a simple concept. Am I missing something simple?

Sounds like for some reason the datamodel isn't getting outjected straight away. Perhaps try outputting a logical outcome and specifying a redirect navigation rule *might* help. Otherwise you could try explicitly clearing the searchResults varialbe in basicSearch() - or try using an EntityQuery which should work ootb.
