Description of problem:
If you import process (attachment 844555 [details]) from bug 1047884 and run simulation (# instances:10, interval: 10 minutes) then you get these results:

  + Process
  |   - Event Process 
  |         -> ("Activity Instances" - "withoutName"[19], a[10], b[10], c[10]) 
  + Process Elements
  |   - a (...)
  |   - b (...)
  |   - c (...)
  |   - (_E2E0224E ....)
  + Paths
      - Path 1 (...)

ID for intermediate throw event is same as for result without name. Graph "Activity Instances" from Event Process shows that this element was invoke 19x but number of instances is just 10. The process does not contain any loop.

If I fill a name of intermediate events (sTh, sCatch) then I get expected results:

  + Process
  |   - Event Process 
  |        -> ("Activity Instances" - a[10], b[10], c[10], sCatch[10], sTh[10]) 
  + Process Elements
  |   - a (...)
  |   - b (...)
  |   - c (...)
  |   - sTh (_E2E0224E ....)
  |   - sCatch (...)
  + Paths
      - Path 1 (...)
