Hello,
I have the conversation scoped component below. Note the @Factory method for initializing the outjected field ListAuctions. And there is a field with get/setters called curScenario. Upon loading a page that uses this component, I get an ELException stating that curScenario can't be read because @Out on ListAuctions is required to be non-null. But if I set ListAuctions to something that's not null ahead of time, the @Factory will never run (because the factory is triggered by ListAuctions being set to null). The Exception does indeed go away if I initialize ListAuctions to something that is non null, but the factory method is never called (which is useless to me). How do I get out of this dilemma? (curScenario can't be read because ListAuctions is null, but if ListAuctions is non-null, the factory is never called.)
(I apologize for not formatting the code with backticks, but that was not working for me.)
Code excerpt:
`
@Name("uifront")
@Scope(ScopeType.CONVERSATION)
public class UiFront {
@In protected EntityManager entityManager;
private Scenarios curScenario;
@Out
private List<Auctions> ListAuctions;
@Factory("ListAuctions")
@Begin
public void initListAuctions () {
AuctionsList AL = new AuctionsList();
ListAuctions = AL.getResultList();
System.out.println ("================ initializing auctionslist");
}
