Menus

[James Spencer]

Menus are just plain driving me nuts and I'm hoping someone can at 
least explain this behavior with the goal that maybe I can understand 
what is happening for future reference.

The particular project at hand uses four stacks, one of which is really 
nothing more than a splash screen although it also contains some 
utility stuff for manipulating the other stacks.  The actual 
application primarily consists of two other stacks.  The fourth stack 
is, at Sarah Reichelt's suggestion (thank you again Sarah) a stack I 
use just for menu development so I don't have to sweat the nonsense of 
how Mac menus are handled.   I created my main menu bar on that stack 
(the group is named "Main Menu Bar") and I use it in the other three 
stacks by "set menuBar of this stack to "Main Menu Bar".  Then, because 
at one time, I had thought it would be helpful to have a different set 
of menus when the utilities in the first stack were displayed, I copied 
my "Main Menu Bar", named this second bar "Utility Menus" and had a 
line in my preOpenStack handler in the utility stack to "set MenuBar of 
this stack to "Utility Menus".  Again, this worked fine and I could 
change back and forth with the correct menus being displayed.

I eventually decided I did not need this second set of menus, that the 
one set would work fine for all purposes just enabling and disabling 
items (as an aside I've reached the conclusion that one thing I don't 
like in Rev's development environment over working with say 
Xcode/InterfaceBuilder or other IDE's is how dramatically the menus 
change depending on context but that's just me) as appropriate.  So, I 
DELETED the "Utility Menus" group from my menu stack.  I've gone 
through all four stacks with the application browser and the group with 
it's corresponding buttons are definitely gone.

Now, here's what I don't get.  I forgot to delete out my line of script 
in the utility stack that "set menuBar of this stack to "Utility Menus" 
and lo and behold, the old menu bar, the one that doesn't seem to be in 
the stack anywhere, continues to appear when the utility stack is in 
front.  How can this be?  I've got my application working correctly now 
by changing the set menuBar line to set the correct menu bar but how 
come I wasn't getting an error when I was setting the menuBar to a 
non-existent menu?  Inquiring minds simply would like to know.
