Chapter 2 : Define performer of an activity

Basic activities with a manual start mode allow the definition of which "performer" can execute the activity.

The "General" tab of the activity dialog allows the definition of many properties of the activity. For a complete description of this dialog, see Activity Dialog.

 

Design time performer assignment:

To define a performer for the activity, select a value in the "Performer" drop down list box. This list displays all the current participants for the workflow project. To add a new participant, select the "New participant" button which will display the  participant dialog.

If "Participant view" is enabled, when a performer is defined for an activity, then the activity icon will be moved into the swimlane for the selected performer.

 

Runtime Performer assignment:

There are two types of performer assignment :

  • Property   - The performer is determined at runtime by the value of the selected property. All properties of the activity are listed in the list for easy selection.

  • Callback - The performer is determined at runtime by calling the specified hook. In connected mode, the deployed hooks are listed. In Offline mode, the hook classname must be entered by the user.
