DataService.getItem()
and DataService.createItem()
methods to provide a way to manage
a reference to the remote object.
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 |
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 | ||
Dispatches an event into the event flow. | IEventDispatcher | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | IEventDispatcher | ||
Releases the managed item reference retrieved with the
getItem() or createItem() method call that returned
this ItemReference. | IItemReference | ||
Removes a listener from the EventDispatcher object. | IEventDispatcher | ||
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

public function releaseItem(copyStillManagedItems:Boolean = true, enableStillManagedCheck:Boolean = true):void
Language Version: | ActionScript 3.0 |
Product Version: | Adobe Digital Enterprise Platform Data Services for Java EE 4.5 |
Runtime Versions: | Flash Player 10.1, AIR 2.0 |
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.
