hibernate tries to persist a second time

bobbele Nov 14, 2007 10:26 AM

hi,
i am not sure if this is a seam or/and hibernate problem, so i try to ask here =)
following scenario:
i have a message that consists of child nodes, files in this case. the user opens a site where he can change the properties of an existing message and add/delete filenodes (using seam fileuploader), this site is backed by a SFSB.
so the user adds two new files to the message, nothing is saved until he presses the submit button. then a method checks for the changes made and syncs them with the db, the code for the filenodes is:

for (FileNode file : fileListadded) {
 if (!message.getChildren().contains(file)) {
 file.setParentNode(message);
 message.getChildren().add(file);
 file.setContentOwner(message.getContentOwner()); // messagebox
 entitymanager.persist(file);
 entitymanager.flush();
 }
}
[...]
// update the message via merge

everything works fine, the changes are synced, the new filenodes are persisted to the db. after that i raise an event so that another controller, which manages different messageboxes, knows that a message has changed.

saveChangesOnExistingItem(message);
// SeamEvent is my private container for custom events
Events.instance().raiseEvent(SeamEvents.EVENT_VIEWMODEL_MESSAGE_CHANGED);
return JSFOutcomes.OUTCOME_EDIT_COMPLETED;

so the changes are saved, the event raised (the messageboxcontroller updates which messagebox to display) and the outcome redirects to the messagebox display, it shows the box which is the parent of the edited message.
the problem is that hibernate tries to persist the new filenodes again after the outcome is returned. so the exceptions is thrown before the page is displayed.

bobbele,

Did you ever figure this out? I am having the same error now that I am using an EntityHome class.

Thanks,

2. Re: hibernate tries to persist a second time

utdrew Jan 10, 2008 10:52 AM (in response to bobbele)

Okay, I think I figured out what my issue was. I convert some entity objects into presentation classes that extend the original entity class when the conversation starts and then back into data classes to persist/merge at the end of the conversation. After further reading of the forums I decided I should probably be calling EntityManager.clear() which solved my issue. BTW, I'm using a Seam managed persistence context.

Thanks,

Drew
