To use an AngularJS participant picker app in a Windchill Client Architecture table, you should define a Windchill Client Architecture action, and point the action to a JSP page that has a participant picker tag. Add the Windchill Client Architecture action you created to the desired Windchill Client Architecture table. When you click the action, it launches the Participant Picker Wizard. Select desired participant and click OK. The picker delivers the selected participant to the application it is supporting.
