Hello,
I am hoping to get some help with some menu code using Squeak 2.7.

menu
ordereCollection do: [: each | menu add: (each printString) subMenu: (self sub)].
menu openInWorld.

sub
add: 'i' action: #i
and so on
sub openInWorld.

Both menu and sub are methods.

When I open the menus on a program and click any of the items in menu to reach the 
submenu, I get two exceptions.

MessageNotUnderstood: delete
MessageNotUnderstood: delete ifPopUp.

Then when I delete the menu underneath are a number of subs (to the size of the 
OrderedCollection).

Where am I going wrong ?

Thanks!
Gary
