8:38 a.m.
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
