[gef-dev] FanRouter and ShortestPathConnectionRouter together

[Christian Dupuis <spring@xxxxxxxxxxxxxxxxxx>]

Hello,

is there a way to use FanRouter and ShortestPathConnectionRouter together?
Because after using the routing of ShortestPathConnectionRouter I still have
connections between the same nodes which are overlapping.

If I use the to routers together

ConnectionLayer cLayer = (ConnectionLayer) getLayer(CONNECTION_LAYER);
FanRouter fanRouter = new FanRouter();
ShortestPathConnectionRouter router = new
ShortestPathConnectionRouter(getFigure());
fanRouter.setNextRouter(router);
cLayer.setConnectionRouter(fanRouter);

I'll get the following stacktrace:
