Problem with copy multiple and entity observer

[DavidBoulder]

I've noticed a bug in our OpenStudio plugin. We have an observer to recognize when new entities are made. What I've found is that if I use the move tool to copy a group that is being observed and then use *3 or /3 (any number in place of 3); I end up with an extra copy of my group at the position where I originally copied it.

Related to this if I use /2 and then /3, I end up with all of the copies made when I did "/2" and all of the copies made when I did "/3". If I do this for non observed objects when I do "/3" right after "/2" the original copies are deleted and then then new ones are made. I think this is the same issue that happens above, the original single copy isn't being deleted before new ones are being made.

Wonder if anyone has run across this, or has ideas on why it is happening and how to fix it. It is really only an issue for groups as opposed to loose geometry. SketchUp automatically corrects for loose geometry on top of each other.

Thanks,

David

Is it not something you are doing within the observer events that interfere?

I was trying all kinds of things with observer when I was working on the DoubleCut plugin - but I don't think I remember this one. But I do remember that handling the multiple copy events was a challenge.
