What Is The Use Of “no Action Group”? |
|
Answer» You can group a set of related ACTIVITIES, with a common set of transitions into and out of the group. If you do not wish for the activities in the group to repeat, specify the group action to be none. No action groups are primarily useful for specifying a single error transition out of the group so that if an unhandled error OCCURS in the group, you only NEED one error transition instead of an error transition for each activity. This behavior is similar to a try...catch BLOCK in JAVA. You can group a set of related activities, with a common set of transitions into and out of the group.
