Dangling Connection with Exception

[bigDevDe]

When dropping the connection to nowhere there is a NPE (the Connection stays green and that dropped point like in the picture):

Does this always happen? I will fix it this weekend.

The demo app that comes with VWorkflows-FX works. Dropping connections is not a problem. Can you tell me more about your exact setup?

[bigDevDe]

This does not always happen.

But sometimes, when dragging a connection, in the middle of nowhere the connector of the line turns green in a certain area (without beeing in the range of another node).

When dropping the line, the above exception occurs.

Sometimes the same with red...
