How to use ShortestPathConnectionRouter [message #179427]

Is there a tutorial that explains why ShortestPathConnectionRouter is
different from the other routers? When I have tried to use it I end up
in an infinite loop in the validate method. Does it require something
more sophisticated than simply creating a bunch of figures and
connections and adding them to a Canvas?

I asked this question once before and got nothing. Silence.

could consider adding more information or looking at the example for
differences.

I've looked at your snippet (we would prefer snippets which compile). You
are adding the connections to the figure containing the obstacle figures to
be avoided by the router. So the connections would be trying to avoid
themselves, which is impossible. The router is desiged for routing
connections on a separate layer outside of the obstacle container.

Ok. I'll try layers. Maybe the javadoc for the router could say
something about this?
