Remarks

Use the object returned by this property to get or set the current Choice Action Item’s settings, stored in this Application Model.

Note that Choice Action Items are loaded to the Application Model if they are created and added to a Single Choice Action’s ChoiceActionBase.Items collection in the Controller’s constructor or using the ChoiceActionItems Collection Editor (see ChoiceActionItem). When they are added “on the fly”, they are not loaded into the Model.
