All Implemented Interfaces:

ReservationEvent, Serializable

public class ReservationUserPropertyEvent
extends ReservationPropertyEvent

ReservationUserPropertyEvent is fired by an IlvGeneralReservation both before and after a user-defined property is modified. Immediately before a property is modified, an IlvGeneralReservation fires an aboutToChange ReservationUserPropertyEvent to all listeners registered with the Gantt data model. Listeners can modify or constrain the proposed property change by calling setNewValue(java.lang.Object). Alternatively, a listener can veto the proposed change by calling IlvPropertyEvent.veto(). If the property change is not vetoed, then IlvGeneralReservation will apply the change and fire a changed ReservationUserPropertyEvent to all listeners registered with the Gantt data model.
