Scott, you are definitely on to something!!!
I took mmalc's ToDos sample and gutted it to be simpler. It still
worked. Then, instead of using the NSArrayController in the NIB I
created one programatically in the MyDocument init method. I have KVC
accessors in MyDocument:
- (NSArrayController *)catController;
- (void)setCatController:(NSArrayController *)aCatController;
Then I change the NSTableColumn binding from:
bind to: Categories (an NSArrayController in the NIB)
controller key: arrangedObjects
model key path: title
to
bind to: File's Owner (MyDocument)
controller key: n/a
model key path: catController.arrangedObjects.title
And changed other bindings analogously. Additionally, I had to bind the
NSTableView's 'content', 'selectionIndexes', and 'sortDescriptors'
bindings as it seems IB does this behind the scenes when the controller
is in the NIB, but not otherwise.
And now I have the same problem as my app! That is, if I change a model
object, the tableview does not update unless I resize the window or
click the tableview. It's as if tableview has simply forgot to redraw.
Text fields update fine, but not table columns.
Shouldn't what I did work?
Thanks,
