The AddAction class defines an action effect that corresponds to the AddChild property of a view state definition. You use an AddAction effect within a transition definition to control when the view state change defined by an AddChild property occurs during the transition.

		applyTransitionEndProperties : Boolean This flag controls whether the effect, when run in a transition, automatically applies the property values according to the end state, as opposed to leaving values as set by the effect itself.	Effect
		endValuesCaptured : Boolean = false A flag containing true if the end values of an effect have already been determined, or false if they should be acquired from the current properties of the effect targets when the effect runs.	Effect

		end(effectInstance:IEffectInstance = null):void Interrupts an effect that is currently playing, and jumps immediately to the end of the effect.	Effect
		getAffectedProperties():Array Returns an Array of Strings, where each String is the name of a property changed by this effect.	Effect
		hasEventListener(type:String):Boolean Checks whether the EventDispatcher object has any listeners registered for a specific type of event.	EventDispatcher
		hasOwnProperty(name:String):Boolean Indicates whether an object has a specified property defined.	Object
		isPrototypeOf(theClass:Object):Boolean Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter.	Object

		play(targets:Array = null, playReversedFromEnd:Boolean = false):Array Begins playing the effect.	Effect
		propertyIsEnumerable(name:String):Boolean Indicates whether the specified property exists and is enumerable.	Object
		removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void Removes a listener from the EventDispatcher object.	EventDispatcher
		resume():void Resumes the effect after it has been paused by a call to the pause() method.	Effect
		reverse():void Plays the effect in reverse, if the effect is currently playing, starting from the current position of the effect.	Effect
		setPropertyIsEnumerable(name:String, isEnum:Boolean = true):void Sets the availability of a dynamic property for loop operations.	Object
		stop():void Stops the effect, leaving the effect targets in their current state.	Effect
		toLocaleString():String Returns the string representation of this object, formatted according to locale-specific conventions.	Object
		toString():String Returns the string representation of the specified object.	Object
		valueOf():Object Returns the primitive value of the specified object.	Object
