Hello again me.
So I solved this doing the following.
Separate the NSColletionViewItem into a different XIB.
In the Main Xib the the Object Controller for the NSColletionViewItem tell it
to load from that new XIB.
Now the funny part, Bindings and Core Data still doesn't work, so what I did
was :
-(void)setRepresentedObject:(id)representedObject{
[super setRepresentedObject:representedObject];
if([[representedObject entity].name isEqualToString:DPA_VERSION_KEY] ){
DPAVersion * ver = (DPAVersion *)representedObject;
self.dataSource = [[NSArray arrayWithArray:[[ver
valueForKey:DPA_VERSION_TO_VERSION_FILES_KEY] allObjects]] retain];
}
}
and then I connect the dataSoruces and delegate of the table view to the File
Owner (which is my subclass of NSCollectionViewItem), and then implemetn the
proper methods and voila it worked..
Now a downside is that I will have to implement the sort of the table because I
lost that feature as Im not using an NSArrayController to populate the table
but a datasource.
