DataModel wrapped data is set to null by ManagedEntityIdentityInterceptor
-------------------------------------------------------------------------

                 Key: JBSEAM-1814
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1814
             Project: JBoss Seam
          Issue Type: Bug
    Affects Versions: 2.0.0.BETA1
         Environment: seam cvs (20070816.1709)
            Reporter: Matt Drees
            Priority: Minor


The following test fails:

@Name("dataModelComponent")
@Scope(ScopeType.CONVERSATION)
public class DataModelComponent extends EntityQuery {

	@Override
	public String getEjbql() {
		return "from java.lang.Object o";
	}
}


public class DataModelComponentTest extends SeamTest{
	
	@Test
	public void test() throws Exception {
		new FacesRequest() {
			@Override
			protected void renderResponse() throws Exception {
				DataModel model = (DataModel) getValue("#{dataModelComponent.dataModel}");
				assert model.getWrappedData() != null;
			}
		}.run();
	}
}

Because the component is conversation-scoped, a ManagedEntityIdentityInterceptor is attached, which nulls the wrapped List after getDataModel() is called.

In the referenced forum, Gavin indicated he hadn't decided whether this should be expected behavior or not, and asked for a jira issue.  

If it is expected behavior (I hope not), I think either EntityQuery should not have a getDataModel() attribute, or it should be documented and/or programmatically enforced that EntityQuerys should not be conversation-scoped.
