EBP work item remains after execution

[Nicholas Brand]

Hello,
 
We're using EBP v3.5.
 
I've created a new task that uses the FORM.HTMLPROCESS method.
I've assigned the web transaction BBPCF02 (Confirm Goods Receipt or
Service) to the task via Goto > Web transaction
 
When I execute the new workitem it works - I go into the create
confirmation screen (BBPCF02), select the relevant PO and create a new
confirmation against it.
When I save the confirmation, I get a message that the confirmation has
been created; however when I return to the inbox, the workitem is still
there.
 
Initially I had no 'Confirm end if processing' or terminating event set.
Then I tried 'Confirm end of processing' - doesn't seem to work with
WebGUI.
Then I tried using a terminating event based on the BUS2203.Saved event of
the new confirmation - also doesn't work.
 
Any other suggestions I could try?
 
 
Kind regards,
Nicholas
