Hi,

When dragging a new arrow for the first time, the following exception is thrown:

Exception in thread "AWT-EventQueue-1" java.lang.ArrayIndexOutOfBoundsException: 23

I had the following attributes set against the flowchart:

flowChart.setArrowStyle(ArrowStyle.Cascading);
flowChart.setRouteArrows(true);
flowChart.setSnapToAnchor(SnapToAnchor.OnCreateOrModify);
flowChart.getRoutingOptions().setTriggerRerouting(
RerouteArrows.WhileCreating);
flowChart.setCanvasBehavior(new BPMNBehavior(flowChart));

Also, please note that this problem did not occur all the time. It happened around two or three times.

I cannot reproduce the problem anymore.

I have put it up here just so you have a reference to it. Maybe it can tip you off to something?

I will let you know if I can consistently reproduce it sometime down the line.


Thanks,

No, I have actually inherited from Box to create my custom classes. These classes have rotation handle turned off.

No, neither of those methods are overriden.
