Workflow Course: Exercise 7

Step 1 - How user can assign task to other

The idea of this exercise is one user assign a task to other

For doing it you should:

• Create two forms in one user will set the user who will execute the next task.
• First task will be assigned to user okmAdmin.
• Create a class which implements AssignmentHandler and assign to taks2.
