I am trying to run an Eclipse GEF-based plugin under Eclipse 3.1M6 with GEF
3.1M6.
For many but not all operations (dragging a node, drawing a specialized
anchor) I get a StackOverflowError.
The plugin did not have this problem with Eclipse 2.1, and I haven't tested
it with 3.0.
What is the cause of this problem?
Did something major change in GEF that I don't know about?
I tried to debug the problem, but didn't get anywhere.
Thanks, Felix

I found two ways to produce the exception:
1. When my diagram is drawn initially, a certain type of connection seems to
cause it. I removed all special drawing from that connection, it didn't make
a difference.
2. When I try to move a node in the diagram.
I don't think moving a node would be native DND, so the answer to your
question would be no.
