[Rubycocoa-talk] Possible bug in key-value handling in RubyCocoa

[Steven D. A. <st...@ne...>]

Following up on my previous post related to the "raiseman" application  
covered in Aaron Hillegass's Cocoa Programming for Mac OS X.....  I  
implemented the same program in Objective-C, an identical analogue to  
the program in Ruby, and it works fine in Objective-C.  That is, the  
expected methods to insert and remove "employee" objects (see below)  
are called in Obj-C but not RubyCocoa.  That tells me there is a bug  
in the RubyCocoa interface that prevents key-value coding from working  
properly.....or possibly I am missing some detail in my implementation  
of the RubyCocoa program.  The Objective-C project which works fine is  
attached.  Run the program, and then add several records and undo them  
by typing command-Z (or selecting undo from the Edit menu).  If you do  
this, the key-value coding will work fine, that is, the following  
methods will be called to undo and redo:

- (void)insertObject:(Person *)p inEmployeesAtIndex:(int)idx
- (void)removeObjectFromEmployeesAtIndex:(int)idx

The equivalent methods in the Ruby implementation are not called:

	def insertObject_inEmployeesAtIndex(p, index)
	def removeObjectFromEmployeesAtIndex(index)

I have also tried these Ruby methods with a trailing _ just to be sure  
that's not the problem.  It didn't change the result.
