Fixing NullReference Exception and not updating nodes on demo site diagram #364

Closed K0369 closed 8 months ago

Fixing a null pointer exception on the demo site diagram, that happened when a link was drawn and released on anything else then a portmodel. Fixes #361.

Fixing the value of the nodes not updating, when the target of a link has changed, because the condition oldTarget == null being never valid.
