Completed!! Below is the testCase that I created (modified from the
workflowpattern#14.)
This test case shows the creation of tasks (from Wfp#14) based on the number of
users that need to be assigned the task. The task node IS NOT complete, until
everyone completes their own assigned tasks.
Thanks Ronald, for your feedback.
