When exporting a process from K2.net 2003 Studio to K2 blackpearl Server non-client events such as Mail Events creates unnecessary records for finish and update actions which are only needed for client events.  This causes the following error when a worklist item is redirected which had a non-client event in the same activity and the new user opens his K2 Worklist: "Item has already been added.  Key in dictionary: 'Finish' Key being added: 'Finish'"

Example Scenario:

  1. Create a process in K2.net 2003 Studio 
  2. Add an activity and add a Mail Event and a Client Event into that activity
  3. Deploy directly to K2 blackpearl
  4. Start a new instance of the process
  5. Open the user's worklist
  6. Redirect the worklist item to another user
  7. Open the new user's worklist
  8. Error occurs
