Despite having successfully written several apps that use bindings, I still
manage to screw it up each time I start a new one.
I have a little object that has an NSMutableArray property called
"connections". I tried to bind an NSArrayController to it, and then bind an
NSTableView to that. But it doesn't work. The array holds NSDictionaries with a
handful of key-value pairs.
Trying to debug things, I created an NSTextField and bound it in turns to the
app delegate, then the property that points to my object, then the connections
property of that object, and finally to @count of the connections property.
It always shows zero, and never increments when new objects are added to the
connections array.
I remembered the need to add some mutable accessor methods, so I implemented
- (void)
insertConnection: (NSDictionary*) inConn
atIndex: (NSUInteger) inIndex
and the removal counterpart. Didn't help. I recall the mere presence of those
in the past fixed my issues, and I could still add and remove objects to the
mutable array directly (via its property).
So I tried calling -insertConnection:atIndex: instead. Still didn't help.
What am I overlooking?
Thanks.
