Image jumps when trying to position it in the centre

[Justin Mclean]

Hi,

This code:

<?xml version="1.0" encoding="utf-8"?>
<js:Application xmlns:fx="http://ns.adobe.com/mxml/2009";
                xmlns:js="library://ns.apache.org/royale/basic"
                applicationComplete="init()">

    <fx:Script><![CDATA[        
        public function init():void {
            image.addEventListener("layoutNeeded", resetImage);
        }

        public function changeImage():void {
            image.src = "http://apache.org/img/flex.jpg";;
        }

        public function resetImage():void {
            holder.dispatchEvent(new Event("layoutNeeded"));
        }
        ]]></fx:Script>

    <js:valuesImpl>
        <js:SimpleCSSValuesImpl/>
    </js:valuesImpl>

    <js:initialView>
        <js:View width="100%" height="100%">
            <js:beads>
                <js:VerticalLayout />
            </js:beads>
            <js:Label text="Here's the ASF logo" />
            <js:Container id="holder" width="520" height="300">
                <js:style>
                    <js:SimpleCSSStyles backgroundColor="#333333" />
                </js:style>
                <js:Image id="image" src="http://apache.org/img/asf_logo.png";>
                    <js:beads>
                        <js:CenterElement />
                    </js:beads>
                </js:Image>
            </js:Container>
            <js:TextButton text="Change Image" click="changeImage()" />
        </js:View>
    </js:initialView>

</js:Application>

Has a visual jump of the image from the bottom right when the image is loaded 
to the centre when the image is centred. Anyone know of any way to stop this 
from happening or any suggestions on what might be done to fix it?

The two images are different height and width so while setting those properties 
fixes the jumping issue it also stretches the second image which is less than 
desirable.

I’ve tried setting the images visibility to true/false but that doesn’t seem to 
get around the issue.

Thanks,
Justin
