Designating an Exception Handler Activity
To designate an activity as an exception handler for a task flow, perform the following steps:
1. Right-click the activity in the task flow diagram, then choose Mark Activity > Exception Handler. A red exclamation point is superimposed on the activity in the task flow to indicate that it is an exception handler.
2. To unmark the activity, right-click the activity in the task flow diagram, then choose Unmark Activity > Exception Handler. If you mark an activity as an exception handler in a task flow that already has a designated exception handler, the old handler is unmarked.
After you designate that an activity is the exception handling activity for a task flow, the task flow metadata updates with an <exception-handler> element that specifies the ID of the activity, as shown in the slide.
