Hello,
please excuse the lousy error description. I must have been in a mood.
What does not work is that no menu items are displayed. The function
correctly returns an NSArray containing NSStrings. But despite of the
bindings the menu is always empty.
What do you mean by KVO compliant? I already have added a
setControlTypes function, this was not necessary in Leopard and also
does not fix the bug in Snow Leopard.
I am pretty clueless and about to change the code and use the
NSPopUpButtonWillPopUpNotification to assemble the menu correctly
before it is displayed. Maybe thats more advisable?
Thanks very much, ALEXander.
