[jboss-user] [JBoss Seam] - Re: Seam 1.3.0.ALPHA entity converter: The instance was not

I'm getting this one too, in code that worked in 1.2.1.GA. (I already voted in Jira). I'm trying to upgrade to Seam 2.0.BETA1 and AS 4.2.GA. I removed all outjection, and stripped it down to the following simple usecase: I have a stateless session bean that returns a list of entities, which are then immediately used to populate a selectOneMenu. Bean: | @Stateless | @Name("itemTextDAO") | public class ItemTextDAOBean implements ItemTextDAO { | | @PersistenceContext | EntityManager entityManager; | | public List<ItemText> getTutorialCategories () { | Query query = entityManager.createQuery ( | "select it from ItemText it where it.itemCode.itemCodeType.name=:name "); | query.setParameter ("name", "TUTORIAL_CATEGORY"); | return (List<ItemText>) query.getResultList(); | } | } | | html: | <h:selectOneMenu value="#{tutorialEditAction.tutorialAdapter.categoryItemText}"> | <s:convertEntity /> | <s:selectItems value="#{itemTextDAO.tutorialCategories}" | var="category" | label="#{category.text}" | noSelectionLabel="-- Select --" > | </s:selectItems> | </h:selectOneMenu> | | I then get the same exception /stacktrace that Felix did. Any ideas for a workaround would be greatly appreciated, or else I'll have to give up on upgrading for now... thanks, Al View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059269#...
