circular update when arrowhead effect in plugin group

[#1]

My plugin creates a plugin group, which generally works fine. When the edit art contains a path with an arrowhead, round corners, or other effects, and I copy that art into the result art, it begins a cycle where the plugin group continually updates itself, then the effect updates, causing the plugin art to again update, until Illustrator crashes.

Is there a way to stop this from happening? The approach I've been trying is to simply expand the arrowhead, but I'm having trouble discovering programatically whether a path even has an arrowhead to expand.

It only happens when the object is selected, though, and the selection-changed notifier is sent. Then the object redraws, and the cycle repeats until it's no longer selected.

Any suggestions would be very much appreciated.

SOLVED: There's no need to mark the art as dirty when the plugin receives the SelectionChanged notifier. It only has to redraw the annotations. Illustrator will redraw the plugin group automatically.
