Are you logging any exceptions

I'd generally prefer enquiries came to the dev list or user list
rather than direct to me.

Although my primary interest is for ArgoUML I've made an effort to try
and make sure other applications are given equal weight. If there are
any problems then feedback is most useful.

The only thing I can think of that may have changed there is this
exception (and similar in setSourcePortFig). I found corrupt diagram
elements in ArgoUML which were hanging around with null ends. This
helped me track down the cause.

    /** Set the Fig reprenting this FigEdge's to-port. */
    final public void setDestPortFig(Fig fig) {
        if (fig == null) {
            throw new IllegalArgumentException("A destination port
must be supplied");
        }
        _destPortFig = fig;
    }


However I'd have expected something to detect the exception and log.

Could you trim the log to just show what happens from the start to end
of drawing an edge?

Each release should contain a readme file which lists the issues
tackled for that release.

There hasn't been any specific work on a birdseye view. However in
theory to JGraphs can be viewing the same layers and quite possibly
with different scales.

There may be plans to implement this in ArgoUML and any work that is
reusable I would think would be brought back into GEF.

Regards

Bob.
