How To add Resource Manager class to UIComponent?

Hi all,

I am using papervision3d as my 3d engine to create anaglyph objects. I want to load 3d objects in diffrent canvas and displayed it based on the selection.

for that i created a list when the list changes using the mouse click the object also changes.i am adding the object in the resourcemanager class. so i load the resourcemanager class to a ui component . but all the objects are loading in to the same scene and it's  behind the component

i give the function

private function selectHandler(event:Event):void {
           
            uploadFile.text = _fileReference.nativePath;
           
            dp.addItem(_fileReference.name);//dp is the data provider to the list
           
            extension = uploadFile.text.substr(uploadFile.text.length - 3, 3).toLowerCase();
            if (  extension == "md2" ) {
                filetype = 0;
            } else if ( extension == "obj" ) {
                filetype = 1;
            }  else if ( extension == "dae" ) {
                filetype = 2;
            } else if ( extension == "3ds" ) {
                filetype = 3;
            } else if ( extension == "kmz" ) {
                filetype = 4;
            }
            myComponent =new ResourceManager(_fileReference.nativePath, perWidth(79), perHeight(80), filetype);
            myComponent.x = 0;
            myComponent.y = 0;
           
            for ( i = 0; i < objectArray.length; i++ ) {
                    objectArray.visible = false;
            }

            currentObject++;
            initViewer.addChildAt(myComponent,currentObject);//here i am adding to the component
           
            list.selectedIndex = currentObject;
           
            objectArray.push(myComponent);
        }

can anyone help me??????please...
