Send mail node disappears after batch run

Hi all,

In one of my workflows I had added a Send mail node and it worked well for some time. Now it seems that after the scheduled batch runs, the node disappears from the workflow...that's really weird, and if I add it again, it is removed on the next run.

If I run the workflow from the workbench it works...

Is there some explanation to this behavior? 

Knime version is 2.11.3.




Hi Angelo,

is there a reason you are still using 2.11.3.

Could you update to our most recent release 3.1.2 and check if the problem still exisits?

Best regards, Iris
