I have an issue that has our team stumped. We have several workflows up on the WebPortal that complete successfully but show the Finished successfully message along with the “Back” button. The Back button (of course) restarts the workflow and let’s you back in at least until the last UI.

I’ve attached a stripped down workflow version of of the problem.
Please let us know your thoughts.

Here’s an updated workflow (removed a node that made it bomb (archive from the original job).
BTW . . . we’re running this one Knime Server 4.16.6
Hello Phil,
I may not fully understand your issue. What would you expect the back button to do?

I’m expecting the workflow to close and not allow access to that workflow again. “Most” of our workflows close out without the back button. Unfortunately, there are a few of our workflow that keep that back button around and we don’t want at add that distraction. When the workflow is complete, they shouldn’t be able to re-enter it.
At the end of our workflows, we save items to the database. The last thing we want is for the user to hit “Back” and end up saving the data twice. (Yes, we can put an switch where they can’t enter the same data twice but, again, we don’t want to add that distraction). From the documentation & experience, the Knime back button returns you to the workflow’s last UI, the browser back button returns you to the workflow’s first UI.
Sometimes the workflow ends with the “Finished Successfully” (with the out of place back button), other times it’ll end where it will return you outside the workflow the “Run” button point.
Any help on this, our team would be great very grateful.
Phil
Am I safe to assume nobody knows how to fix this?
