Extracting a reference to a stack

Ah thats too bad.
I guess the other idea could still work. Dispatch a message to the object
Change getprop to..
return the name of this stack
To get at the information just
dispatch "owningstack" to myLongId
put the result
I have a feature request.. The ability to return a long id as an array
keyed by numeric order AND object type of possible. Keys something like
1b,2g,3g,4g,5s,6s. 1b would be the button in question, that is in group 3
nested groups, on a substack of the mainstack. 6s would contain the
mainstack reference. In this way it should be easy to pick out what you
want, and obviate the need to worry about namings that throw so many other
Also, it just occurred to me.. Messages can be passed.. (doh)
So would it be possible to dispatch a message (that is in a library) that
grabs the id of a level, then pass to the next, and build a reference list
IE dispatch it to button 1 of group 1 of substack 1 of stack 1 .. passing
it each step of the way until the mainstack is hit?
