Description of problem:

Consider a parent process that calls a reusable child process. When you view the parent instance in the Process Management -> Process Instances screen, you can see that the parent calls the child process. There is a small plus sign on the child process. It looks like clicking on the plus sign will allow you to see the child process. However, I get an error message on the screen that says "Unable to find called process."

See the forum reference link for a screenshot:

Version-Release number of selected component (if applicable):
BPM Suite 6.1.2

How reproducible:
Always

Steps to Reproduce:
1. Create a new project in the JBPM workbench
2. Create a new business process that will be the child process
3. Create a new business process that will be the parent process
4. In the parent process, add:
a user task step that will make the process halt at that step
a reusable subprocess that calls the child process
5. Build and deploy the project
6. Run the parent process (it should halt at the first step)
7. Go to the Process Management -> Process Instances screen
8. Select the instance of the parent and click View -> Process Model
9. Click the plus sign on the child process task (you should see the error message pop up in the window)
