Issue/Introduction

Open Workbench is crashing is a few scenarios including:

  • Closing a project in OWB
  • Adding a new task after filtering on phases and one resource 

There was a defect that was fixed (DE49803) in 15.7 patch 1, but in 15.7 patch 1, there are still some crashing issues as noted above. 

Steps to Reproduce when closing a project in OWB:

  1. Open OWB and click the New icon to create a new project
  2. Create two tasks
  3. Add a resource to the project in OWB
  4. Assign the resource to one task
  5. Save the project locally
  6. Click the x right next to the project name in OWB to attempt to close the project (not the x in the upper right hand corner that closes OWB completely)

Expected Results:  Save is successful and OWB remains open

Actual Results: OWB crashes with error npWBench.exe has stopped working. (Clicking the Close Program message in the error popup up window closes OWB)

  2. Create three tasks: Make the first task a phase, the second task an activity, and the third task a regular task

  4. Assign the resource to the child task (the third task)
  5. In the Task menu options, select the resource from step 3 from the drop down, and change the Type from Task to phase

Expected Results:  Task is created successfully
