[flex_india:32818] Creating clone for Display Object

[Shalu]

Hi All,

Does anyone have idea about creating clone for a display object. I
read about ObjectUtil.copy and byteArray technique, but these do not
work for display objects.

I am facing this issue in displaying a component in popup, making some
changes in contents, and on cancel button click I do not wish to save
the changes. Please refer below code:

TestApplication.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute">
        <mx:Script>
                <![CDATA[
                        import mx.controls.Alert;
                        import mx.managers.PopUpManager;

                private var testComp:TestComp = new TestComp();


                private function btnClickHandler():void
                {
                        var testComp1:TestComp = new TestComp();

                        testComp1= testComp;
                        
testComp1.addEventListener("closePopup",removePopupFromdiaplyList);
                        PopUpManager.addPopUp(testComp1,this,true);
                }

                private function removePopupFromdiaplyList(event:Event):void
                {
                        PopUpManager.removePopUp(event.target as TestComp);
                }

                private function clone(source:TestComp):TestComp {
        var copier:ByteArray = new ByteArray();
        copier.writeObject(source);
          copier.position = 0;
        return(copier.readObject() as TestComp);
        }

                ]]>
        </mx:Script>
        <mx:Button label="displayPopup" click="btnClickHandler()"
        />
</mx:Application>


TestComp:

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml"; width="400"
height="300"
        showCloseButton="true" close="dispatchCloseEvent()"
        >
        <mx:Metadata>
                [Event(name="closePopup", type="flash.events.Event")]
        </mx:Metadata>
        <mx:Script>
                <![CDATA[
                        import mx.managers.PopUpManager;
                        private function dispatchCloseEvent():void
                        {

                         this.dispatchEvent(new Event("closePopup"));
                        }
                ]]>
        </mx:Script>
        <mx:VBox>
                <mx:TextArea width="100" height="100"/>
        </mx:VBox>

</mx:TitleWindow>

Please share you knowledge on cloning a display object.

Thanks in advance!
