Description Tim Buschtoens CLA 2011-04-08 12:07:53 EDT 
To reproduce use workbench-demo with business design, hover the same tool-item twice: 

Javascript error occurred:

Error: Could not apply state appearance TypeError: node.parentNode is null

I commited a quickfix using try-catch to CVS HEAD. It seems to have no side-effects. I will try to find a real solution as soon as possible.
Comment 2 Tim Buschtoens CLA 2011-04-11 05:09:03 EDT 
Fixed in CVS HEAD.

The exact problematic order was this:
- setting a rounded border / no gradient
- flush
- setting no border
- flush
- setting gradient
- flush

GraphicsMixin would not understand that the shape from the border was already removed when setting the gradient.
