Can An Object Know About Itself?

Another thought, use a frontscript.
As a test I created a group with several objects including 1 button to use
For the group, this:
if the long id of button "fscriptb" of me is not among the lines of the
insert script of button "fScriptb" of me into front
put the long id of me & random(1000)
For the button this:
on selectedobjectchanged pVar
set the oldSelected of this stack to the nowSelected of this stack
set the nowselected of this stack to the selectedobjects
put the oldselected of this stack
if the oldselected of this stack is not empty then dispatch
"rossiObjectDeselected" to (the oldselected of this stack)
It seems to work ok, though it doesn't take into account multiple instances
of the group, so perhaps another property to determine if the script has
been inserted into front already or not. Then use that property rather
than the contents of the frontscripts to decide whether or not to insert
the script into front.
