[Drawkit] respondsToSelector

[James Maxwell]

Okay, just as a test, to see if I'm really as incompetent as I seem to  
be, I tried making a menu item to execute "Convert To Path" from  
DKDrawableShape. The object I'm working with is a subclass of  
DKDrawableShape, so it should be able to respond to the IBAction.
So, I created a menu with an item for Convert To Path, added an action  
for convertToPath: to my First Responder, and connected the menu item  
to First Responder's convertToPath: action.
I launched my app, added one of the said DKDrawableShape subclass  
objects to the drawing, and sure enough, Convert To Path became active  
in the menu, and selecting it performed the conversion.

So, I do exactly the same thing for the custom method that I want  
performed. The method is declared as an (IBAction) (just like  
convertToPath:) and I've added it to the First Responder in IB. I  
connect it up, and I test it out and... nada... nothing. The menu item  
doesn't become active when I select the object, so obviously, nothing  
happens.

I don't see any logical reason why this isn't working. And I've had  
strange problems with IB before.

Does anybody have any suggestions... This is driving me crazy.
