Have only tested it briefly, but there is still an issue with a node that doesn’t have a parent yet.
The Eclipse and the JVM are unfortunately rather uncooperative. Debugging this isn’t exactly easy, because for half of the objects Eclipse refuses to give me any information.
Is this a known issue? I set the debugger to suspend the VM once an illegal state exception is hit. That doesn’t seem to be a good idea.

Will try to look into it later today.

Thanks
Stefan
