PM73896: APPLYING THE 'NAME COMPARTMENT ONLY' FILTER ON A BPMN POOL GIVES A NULLPOINTEREXCEPTION ERROR

APAR status

• Closed as program error.

Error description

• If you apply the 'Name Compartment Only' filter on a BPMN pool,
  you will get a NullPointerException after you close and open the
  model.
  
  The following steps reproduce the problem:
  
  1. Create a new blank collaboration model inside a BPMN project
  2. Create a new pool with a new process for that pool
  
  3. Add a new lane to the pool
  4. Click on the pool and select Filters ? Show/Hide compartment
  ? Name Compartment Only from the context menu
  5. Save and close the project
  6. Open the project and BPMN diagram
  
  Expected Result: The diagram opens without any error messages.
  
  Actual Result: The 'Could not open the editor: An unexpected
  exception was thrown.' error message appears and the following
  NullPointerException output gets generated:

  The workaround is to avoid using the 'Name Compartment Only'
  filter for BPMN pools.
