I'm detaching a thread to handle some processing. In that thread, I
create a new NSManagedObjectContext using the same
NSPersistentStoreCoordinator from the main thread. I pass into the
thread the NSManagedObjectID of an entity and my thread creates new
entities and adds them as children of the existing entity. When the
thread finished, it saves the Managed Object Context, then calls a
method on the main thread that tells the application's main MOC to
refreshObject :mergeChanges, passing in the managed object that I
added child entities to. I specify YES for merge changes (although
using NO doesn't change the results), and then tell it to
processPendingChanges.
The data gets correctly saved, but the NSOutlineView and
NSTreeController I'm using to display the object and its children
doesn't realize it. If I quit and come back in, all the stuff that was
added in the thread shows up, but as long as the application is
running, the results never show up.
Am I missing some step I need to take in order to tell the outline
view or the tree controller that one of the objects it is showing has
been updated?
TIA,
Jeff
