Hi
I have just had an exception thrown on some relatively recent code, that has worked fine until now..
java.lang.IllegalStateException: Cannot obtain globalId for an object which is registered in its editingContext,
object: <indoc.app.entities.Container pk:"496">,
databaseContext: er.extensions.eof.ERXDatabaseContext@ee260b,
object's editingContext: er.extensions.eof.ERXEC@1fe6055,
databaseContext's active editingContext: null
Context:
This is part of a background notification system which works roughly like:
1) NSNotificationCenter triggers a callback that...
2) Creates a new Runnable and globalIds of objects are passed into this runnable from their original editing context. A ThreadPoolExecutor the executes the thread.
3) The new thread creates a new editing context that uses an ERXRoundRobinCollection to grab an EOObjectStoreCoordinator. This EOObjectStoreCoordinator is only used in the notification part of the application, and the ERXRoundRobinCollection contains just a couple of instances of a EOObjectStoreCoordinator at a time.
The ec is created with:
ERXEC notificationtEC = (ERXEC) ERXEC.newEditingContext(objectStoreCollection.nextObjectStoreCoordinator());
and the EOObjectStoreCoordinators with:
ERXObjectStoreCoordinator osc = new ERXObjectStoreCoordinator(true);
4) I then use the newly created notificationtEC to convert the globalIds back to EOs like.. eo = ERXEOControlUtilities.convertGIDtoEO(notificationtEC, gid);
5) I then use the same notificationtEC to fetch various objects etc to build the notifications and send out an email.
The full stack trace is below.
I was under the impression that having a new database stack should be a pretty safe way to do such a task in a separate thread. Do you have any idea what I am doing wrong?
I do not quite understand the meaning of the above java.lang.IllegalStateException Any ideas much appreciated.
Thanks
Giles
