(This basically adds some application-specific checks to the canRemove: property, so that I can bind a "remove" button in Interface Builder.)

Question: why aren't you just overriding -canRemove?

Good point. For some reason, it hadn't occurred to me to do that.

However, I also need to add another, similar property: -canChoose (which does something subtly different) so my problem stands.


However, the accessor for the property (i.e., "- (BOOL)canRemoveSelection") is never called, beyond the initial call when the object is created. As a result, the button bound to the property never changes state.

Have you actually bound anything to the controller's canRemoveSelection property?


Yes, I have, but I will go do a sanity check right now...

But everything else seems to make sense?

Thanks,
Alex
