Something strange is happening with my coredata app, and it has to do
with NSArrayController and some objects bound to it.
I have an NSPersistentDocument app, and an NSArrayController that is
subclassed to return a special NSPredicate to sort another NSArray.
Now, My NSDocument subclass has a reference to said NSArrayController
(lets call it peopleController) set in IB.
From the NSDocument I set two keys for strings to peopleController
so it can create a correct NSPredicate other objects will use.
Bound to peopleController I have a NSTableView, all bound in IB. My
controller is supposed to re-process the NSPredicate if the
selection changes (by the table view). The totaly strange thing is
that the peopleController that is linked to the NSDocument subclass,
and the on bound to the NSTableView are NOT THE SAME CONTROLLER!!
This means that somewhere my class of controller is being re-
created?? Also, setSelectedObjects is not being called by the
tableview, but
setContent............... I cant create the NSPredicate I need based
in selection because the NSTableView is not changing my selection!
Whats going on? Does coredata do tricks behind my back? I cant rely
on the object being bound to and the one set in IB to be the same?
NSPersistentDocument ------>peopleArrayController

NSTableView ----B-I-N-D-I-N-G---------NOT THE SAME?? (I've checked by
pointer and they are not the same object)
