[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1814) DataModel wrapped data is set to null by ManagedEntityIdentityInterceptor

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 Assigned To: Norman Richards Priority: Minor Fix For: 2.1.x 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.
