public abstract class UIStrategyHandler
extends UIStrategyCoordinatorMng

This part of the UIStrategy Stack deals only with communications between the UIHandlers and the IDialogManager.

the messages exchaged are:

1. userLogOn: notifies the IDialogManager when a user has logOn at a handler.
2. NotifyHandler: the IDialogManager is sending a new UIRequest or updating an existing one.
3. FinishDialog: the UIHandler notifies the IDialogManager a user has finishied a dialog, the UIResponse goes in this message.
4. CutCall: this is a synchronous call, the bus is telling the UIHandler to derenderize a certain dialog, and it is expecting (and waiting) for the dataRoot of the Form.
