Question

flex 4.6

I am using addElement as below. I note however that when inspecting the element, the name of the element is suffixed with a number, so the loaded element name of newMod becomes newMod10 (number is variable). If I want to then removeElement() I have no idea of what the correct getChildByName() would be, so getChildByName("newMod") fails.

So my Q’s are

1. how do i addElement() with a unique name
2. how do find the name of the element I just added so I can reference by the nameXX

thx

/*  load module */
/*   creationComplete="loadNewMod('modToLoad','A' )
public function loadNewMod(modName,evtTyp):void {
   info = ModuleManager.getModule(modName);
   var self:Object = this;
   var meh =  "modEventHandler"+(evtTyp);
       info.addEventListener(ModuleEvent.READY, function(e:ModuleEvent){
        self[meh](e)
            });
   info.load(null, null, null, moduleFactory);
   }

private function modEventHandlerA(e:ModuleEvent):void {
   vg1.addElement(info.factory.create() as IVisualElement);
  }


<s:Group id="vg1" horizontalCenter="0" verticalCenter="0">
    <s:Label id="newLabel" />
</s:Group>

[EDIT]
by breaking out the function I have added an ID that seems to work

private function modEventHandlerA(e:ModuleEvent,fcall):void {
   var newID = info.factory.create();
   newID.name = "myElem";
   vg1.addElement(hh as IVisualElement);
   }

Best way is likely to attach a name property to the object and do a for loop. It’s inefficient, but the ID label doesn’t seem to work properly when setting it in AS3.

info.name = "info1";


for ( var i:Number = 0; i < vg1.numElements; i++ ) {
     if ( ( vg1.getElementAt(i) as UIComponent).name == "info1" ) {
         vg1.removeElementAt(i);
         break;
     }
}

I didn’t check to see if info would have the name property, but that would do the trick. Alternatively, you could use the exact same method with the id tag, except use indexOf(“info1”) >= 0, instead of .name == “info1”
