The IItemReference interface provides the contract for a ItemReference. An instance of ItemReference is returned from the DataService.getItem() and DataService.createItem() methods to provide a way to manage a reference to the remote object.

Public Properties

	Property		Defined By
		valid : Boolean Set to false if the ItemReference becomes invalid either because the server faulted when trying to retrieve the item or if the retrieved item was itself null.	IItemReference

Public Methods

	Method		Defined By
		addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event.	IEventDispatcher
		dispatchEvent(event:Event):Boolean Dispatches an event into the event flow.	IEventDispatcher
		hasEventListener(type:String):Boolean Checks whether the EventDispatcher object has any listeners registered for a specific type of event.	IEventDispatcher
		releaseItem(copyStillManagedItems:Boolean = true, enableStillManagedCheck:Boolean = true):void Releases the managed item reference retrieved with the getItem() or createItem() method call that returned this ItemReference.	IItemReference
		removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void Removes a listener from the EventDispatcher object.	IEventDispatcher
		willTrigger(type:String):Boolean Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type.	IEventDispatcher

Set to false if the ItemReference becomes invalid either because the server faulted when trying to retrieve the item or if the retrieved item was itself null. This property can be used to bind to your user interface controls to display status information for this item without having to listen for explicit fault events.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.

Implementation
public function get valid():Boolean
public function set valid(value:Boolean):void

Releases the managed item reference retrieved with the getItem() or createItem() method call that returned this ItemReference. It is possible to have more than one ItemReference that points to the same item on the same client. Use this method to release the proper reference.

Parameters

	`copyStillManagedItems:Boolean` (default = `true`) — Boolean indicating that a copy of this item should be placed in this ItemReference should the current item still be referenced. This can occur if more than one call to `DataService.getItem()` for this same item is made, or if this item is referenced by a collection returned from a call to `DataService.fill()`.

	`enableStillManagedCheck:Boolean` (default = `true`) — Boolean indicating if the item should be checked for additional references.
