Warning Indicator (with continued execution)

The Table Creator node seems to be able to display a Warning Icon even though execution is continued - so I'm guessing it is not a CanceledExecutionException.  Is there some way to trigger this warning sign for Nodes that can continue to execute but have concerns over validity of execution?

NodeModel.setWarningMessage() is your friend :-)

thor (god of knime developer's forum) is my friend ;)

Okay - now reversing the question on you ;)  I have a node that will always output an empty table (it is basically outputing an empty DataTableSpec to enhance Try/Catch behavior).  Is there a way to *stop* the automatic "Warning: Empty Table Created" message? ;)

No, this is not possible.
