Comments on: Deep Object Copy

You try to copy an AdvancedDataGridItemRenderer using the code provided for a bitmap. That will not work (as you saw it) because they are incompatible type. Instead use ObjectUtil.copy(). It should work ok. If you get an error when you recast the result back to your normal object use the register alias method explained above.

I tried using this to create a copy of an AdvancedDataGridItemRenderer instance, but I got a runtime error:

var dispObject:DisplayObject = DisplayObject(copyBitmap(DisplayObject(lineItemEntityRenderer)));


addChild(dispObject);
function copyBitmap(target:DisplayObject):Bitmap

{

    // Create the bitmap data object with the right size.

    var data:BitmapData = new BitmapData(target.width, target.height, true, 0);
    // Draw the target object into the bitmap data.

    data.draw(target);
    // Create a new bitmap object associated with this data.

    var bitmap:Bitmap = new Bitmap(data);

return bitmap; }

Runtime Error:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Bitmap@11827bf1 to mx.core.IUIComponent.
