Weird bindings problem
Weird bindings problem

I have a few controls that use two 'enabled' bindings, and I get this
error
*** -observeValueForKeyPath:ofObject:change:context: only defined for
abstract class. Define -[NSCFString
observeValueForKeyPath:ofObject:change:context:]!
If I reduce this to just use one 'enabled' binding, it works fine, to
make this even weirder, if I put the 2nd enabled binding back in, but
switch the order of the bindings, i.e. enabled becomes enabled2, and
enabled2 becomes enabled, it works fine!
I've seen this happen loads of times, and I can replicate the problem.
I have a workaround, so it's that big a deal, but I'd like to know
what's going on, any ideas?
Cheers
Moray
