I can't understand why I'm getting a StaleObjectStateException in my action. Or
rather, I understand why, but I don't understand why the entity is not up to
date.
This is a simplified version of my action:
| @In(create = true)
| EntityManager database;
|
| @In
| @Out
| private User loggedInUser; //created by Authenticator
|
| @DataModel
| private List<ListBidItem> listBidItems = new ArrayList<ListBidItem>();
|
| @Begin(join = true)
| public void addBidItem(ActionEvent event){
| ListBidItem newItem = new ListBidItem();
| listBidItems.add(newItem);
| }
|
| @End
| public void yesConfirmSave() {
| confirming = false;
| //database.refresh(loggedInUser); //doesn't seem to help
| Date now = new Date();
| Bid bid = new Bid();
| bid.setCreatedOn(now);
| bid.setCreatedBy(loggedInUser);
| bid.setBidder((Bidder) loggedInUser);
| ((Bidder) loggedInUser).setBid(bid);
|
| for (ListBidItem lbi: listBidItems) {
| BidItem bi = lbi.getBidItem();
| bi.setCreatedBy(loggedInUser);
| bi.setCreatedOn(now);
| bi.setBid(bid);
| bid.getBidItems().add(bi);
| }
| database.persist(bid);
| loggedInUser = bookBuildingDatabase.merge(loggedInUser);
| }
|
pages.xml is simple:
| <page view-id="/restricted/createBid.xhtml">
| <restrict>#{s:hasRole('Bidder')}</restrict>
| <navigation from-action="#{bidderBidManager.yesConfirmSave}">
| <end-conversation/>
| <redirect view-id="/restricted/createBid.xhtml"/>
| </navigation>
| </page>
|
The User entity has a property:
| @Version
| @Column(name="VERSION")
| protected int version;
|
Now, when yesConfirmSave is called the first time after log in, everything
works fine. When the user trues to save a second Bid, however, the
StaleObjectStateException is thrown. From debugging the addition of the second
bid, I can see that the the loggedInUser's Bid is correctly set, but the
version number is not up to date. Adding the database.refresh() call does not
seem to help either.
(I know the use case does not make sense, seeing as a user can only have one
bid, but please disregard that :) )
Thanks
