With delegation you can delegate a task to any user in the organizational structure defined. You may want to show your own list of people for delegation in a Web Panel, but If you do not write an object name indicating where the user can choose a delegation, GeneXus will show its own window dialog.
Note: This property is active only if the value of the Allow Delegation property is set to True.
