Scaleform - iPad - runtime movieclip generation

[paradoc]

Has anyone had any issues with scaleform/flash movieclips generated at runtime on the iPad platform? (iPad 2 running iOS7). this seems to work fine on an iPhone 4s, but for some reason they don't appear on the iPad.

function playActiveMessage(){

	local GFxObject myTextMessage;
	local vector2D screenDims;
	
	if ( myMessageList.Length != 0 ){
		myTextMessage = GetVariableObject("root").AttachMovie("textMessage","messageInstance");
		myTextMessage.GetObject("message").SetText(myMessageList[0]);
		//place it in the center of the screen
		GetGameViewportClient().GetViewportSize(screenDims);
		myTextMessage.SetPosition(screenDims.X/2, screenDims.Y/2);
		//remove it from the list when we've generated it
		myMessageList.Remove(0,1);
	}

}

[EDIT]
was able to find out where the issue was, but wasn't able to find a solution using direct screen positioning control.

GetGameViewportClient().GetViewportSize(screenDims ); screenDims were providing the correct resolution on both devices, but i guess i don't really understand authored global scale because i thought both were retina displays meaning i could have used screenDims/2 to get the center of the screen. not true. iPad2 required screenDims/4.

so to avoid any cross compatibility issues, any dynamically generated movieclips have registration points at 0,0 to avoid any future problems. everything works fine now.
