Seems like no process definition ID is associated to the execution, which is really odd. Do you have a simple test-case for this issue? (see sticky on forum how to create unit-test)

I have an example that can recreate this issue. I am new to Activiti, so I was not sure if this user had already posted an example in Jira which I have not used yet. What did you mean by "see sticky on forum"? Also, I have noticed process images posted on this site, but was not sure how to attach an image, can you advise?

Our proprietary workflow implementation supports quartz-based timers and we allow designers to specify a time (when the timer fires) as well as a repeat cycle. So, I have a Review task that has a boundary timer event that fires after 3 min (PT3M). I added 2 transitions, one to a mail task and the other to an intermediate timer event that repeats twice every 2 mins. I get the first email after 3 min as expected as well as the second email 2 mins later, but the second firing of the intermediate timer event generates a NPE and the intermediate timer and its transition stay active in the Activiti Explorer instance view. See attached process template for details.

I have a JIRA account, so I will open an issue in codehaus.
