Hi all,

I tried asking a similar question earlier, but not sure if it posted or
not.  If this is ends up duplicating what I tried to post earlier, I hope
one of them gets deleted.  Here goes:  

Is there an event that can be captured when you click the "undo" icon on an
insert_at event type?  For example, if you move a node on a polyline you
can add a listener for the set_at event on the initial move.  If you click
the "undo" icon immediately afterwards, it fires another set_at event which
can be captured by your listener for the set_at event.  However, if you
"insert" a node on a polyline, an insert_at event can be captured with a
listener, but if you click the "undo" icon, it appears that an insert_at
event is not fired because the listener does not capture that "undo" as the
previously mentioned set_at event does.  Logically, these seems correct
because at that point, I would not consider it to be an insert_at event.  
So again, is there another event being fired such that a listener can be
added to capture the "undo" event of an insert_at event?  I do not see
anything in the documentation stating as such, but that doesn't mean I did
not miss something.  Any help would be appreciated.

thank you,
