In certain situations I am seeing an exception when drawing a connector
from one figure to another in my GEF drawing. The exception seems to be
coming from the GEF and draw2d. This only occurs when I am attempting
to reconnect an existing connection and happens while I am moving the
end of the connector.
I have been looking at this for some time and can't seem to find the
root cause. I haven't found anything in the news group. Please let me
know if anyone has any ideas or additional information is necessary.
Here is the stack trace:

Thanks for the guidance. I was able to track it down to the problem
section of code.
In my ConnectionEditPart (extends AbstractConnectionEditPart)
createEditPolicies I was installing the following edit policy :
installEditPolicy(EditPolicy.CONNECTION_BENDPOINTS_ROLE, new
PartConnectionSelectionHandlesEditPolicy());
When I comment that line out, I no longer have the problem. This was
probably due to an improperly extended SelectionHandlesEditPolicy. Here
is the policy
public class PartConnectionSelectionHandlesEditPolicy extends
SelectionHandlesEditPolicy {
public PartConnectionSelectionHandlesEditPolicy() {
super();
}
protected List createSelectionHandles() {
List list = new ArrayList();
ConnectionEditPart connPart = (ConnectionEditPart) getHost();
PointList points = getConnection().getPoints();
for (int i = 0; i < points.size() - 2; i++) {
BendpointHandle handle = new BendpointCreationHandle(connPart, 0,
new BendpointLocator(getConnection(), i + 1));
list.add(handle);
}
return list;
}
protected Connection getConnection() {
return (Connection) getHostFigure();
}
}
Thanks,
Patrick
