Step 1 - How user can assign task to other

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

To do 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.

    @Override
    public void assign(Assignable assignable, ExecutionContext executionContext) throws Exception {

        if (username != null) {

            assignable.setActorId(username.getValue());
        } else {

            assignable.setActorId("okmAdmin");
        }
    }
