Column comparator node

The Column comparator node throws the following error:
failed to apply settings: javax.swing.JPanel cannot be cast to javax.swing.JTabbedPane when trying to configure it.
Any idea? Where do I start to look for the reason?

We can confirm, it's a bug in our node implementation, class ColumnComparatorNodeDialogPane.  It seems that this bug originate from a change in our dialog framework that is not covered by our test cases.

Depending on the task you are trying to perform, the Rule Engine node might help to overcome the problem. The bug will be fix soon. Sorry for this hassle.

Thanks, I can re-arrange the task.
