[news.eclipse.tools.gef] Re: IndexOutOfBoundsException in

["Randy Hudson" <none@xxxxxxxxxx>]

Try hard to reproduce in the logic example.  That way we can reproduce it 
and debug.

It looks like the number of bends in the connection might be changing as you 
drag the connection around, and the bendpoint editpolicy for some reason is 
not rebuilding its handles when this occurs.  Therefore, it ends up with a 
handle referencing a bend index which is too large.

the policy should track the "points" property of the connection, and refresh 
its handles if the number of points changes.
