I've got 3 process instances that have stopped at the same place (1500 others are OK). Using the K2 reports page it shows the activity as being active with the proper destination user. However, the user didn't receive an email notification (infopath client event), doesn't have a task in his K2 Tasklist, and when I check it using Server Manager there is no worklist item for that activity.
I've added a jpg attachment that is actually two images in one. The top one shows a partial K2 report view of the activities so far, and the other is a snip of the viewflow diagram for this part of the workflow. There is also more text describing the workflow.
So:
- The destination rule has executed and assigned the correct user.
- There is no start rule
- The activity was instantiated.
- The Infopath Client event (first event of activity) creates the Infopath XML file for the activity and sends an email to the user. This has not occurred
Why didn't the event fire? What can I do to get this corrected?
