Hi,
Yes my Document class releases the array in its dealloc method and all Node
objects in the array are properly dealloc'ed when deallocing the document.
However, I think the problem is unrelated to the retaining of the array
member of the document class but rather to the retaining of elements added
to the array via NSTreeControllers add:sender and remove:sender class.
Adding a node object through this method creates a node object in the
document array member with a retain count of 2. The remove:sender method
correctly removes the object from the document's array but only decrements
the node object's retain count to 1 - meaning that the objects are never
dealloc. As I see it, this is a memory leak in NSTreeController as all "my"
external references to the Node objects are lost.
Thanks,
Mads
