>                 Key: JBSEAM-1814
>                 URL: https://jira.jboss.org/jira/browse/JBSEAM-1814
>             Project: Seam
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 2.0.0.BETA1
>         Environment: seam cvs (20070816.1709)
>            Reporter: Matt Drees
>            Assignee: Norman Richards
>            Priority: Minor
>             Fix For: 2.1.1.CR1

> 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.
