Description Dan CLA 2010-01-06 13:39:12 EST 
I have no problem calling deactivationFigure() in AbstractConnectionEditPart if my figure (PolylineConnection) doesn't have a decoration.

As soon as I add a "decoration" to my figure,
PolygonDecoration sourceDecoration = new PolygonDecoration();
((PolylineConnection) connectionFigure).setSourceDecoration(sourceDecoration);

deactivationFigure() gets ArrayIndexOutOfBoundsException.

Here is the stack trace.

java.lang.ArrayIndexOutOfBoundsException: -1

Comment 1 Alexander Nyßen CLA 2010-11-21 15:46:26 EST 
Looking at the stack trace this seems to be something related to ShortestPathConnection router. However, I fear that from the provided information alone, this will not be reproducible. Could you provide a code snippet that could help to reproduce the problem?
