Some input on this would be greatly appreciated.

Thanks,

Thanks, I will give that a try.

Unfortunately I cannot use scrolling since the entire text must be visible to the user as one chunk.

Thanks guys, that's extremely helpful.

Using the tips above I now have something that may become a workable solution. Remember I need a pure AS3 based approach for a RTL text object that supports a dynamically resizing container. Here's a test class I created that allows you to pass in a reference to a container (I use a Canvas) and then adds the text to it. Maybe someone else will find this helpful.

package {

    import flash.geom.Rectangle;

    import flashx.textLayout.container.ContainerController;

    import flashx.textLayout.edit.EditManager;

    import flashx.textLayout.elements.ParagraphElement;

    import flashx.textLayout.elements.SpanElement;

    import flashx.textLayout.elements.TextFlow;

    import flashx.textLayout.events.CompositionCompleteEvent;

    import flashx.textLayout.formats.Direction;

    import mx.core.UIComponent;

    /** This example demonstrates custom event handling on a LinkElement.  In one case a click handler is added to a LinkElement.  In the other class the click handler is a event:EventName string.  */

    public class TLFWrapper extends UIComponent

    {

        private var textFlow:TextFlow;

        private var pCustomClick:ParagraphElement;

        private var pNamedEvent:ParagraphElement;

        private var _container:UIComponent;

        private const PADDING:int = 10;

        private const PADDINGBOTTOM:int = 25;

        public function TLFWrapper( container:UIComponent=null )

        {               

            this._container = container;

            textFlow = new TextFlow();

            textFlow.fontSize = 18;

            textFlow.paragraphSpaceBefore = 2;

            textFlow.paragraphSpaceAfter = 2

            textFlow.paddingBottom = textFlow.paddingTop = textFlow.paddingLeft = textFlow.paddingRight = PADDING;

            textFlow.direction = Direction.RTL;

            var p:ParagraphElement = new ParagraphElement();

            var s:SpanElement = new SpanElement();

            textFlow.addChild(p);

            p.addChild(s);

            s.text = "وثيقة إثبات صلة القرابة مصدقة من سفارة دولة الإمارات – إذا لم يكن اسم المكفول مدرجاً في جواز سفر";

            textFlow.flowComposer.addController(new ContainerController(this, NaN, NaN));

            textFlow.flowComposer.updateAllControllers();

            var controller:ContainerController = textFlow.flowComposer.getControllerAt(0);

            var rec:Rectangle = controller.getContentBounds();                       

            _container.width = rec.width;

            _container.height = rec.height;

            controller.setCompositionSize( _container.width, _container.height );

            textFlow.flowComposer.updateAllControllers();

            textFlow.interactionManager = new EditManager();

            textFlow.addEventListener(CompositionCompleteEvent.COMPOSITION_COMPLE TE, onCompositionComplete);

        }

        protected function onCompositionComplete(event:CompositionCompleteEvent):void

        {

            var controller:ContainerController = textFlow.flowComposer.getControllerAt(0);

            trace(controller.compositionWidth + " x " + controller.compositionHeight);

            var rec:Rectangle = controller.getContentBounds();

            _container.width = rec.width;

            _container.height = rec.height;

            controller.setCompositionSize( _container.width, _container.height );

            textFlow.flowComposer.updateAllControllers();

        }

        public function addText():void

        {

            var para:SpanElement = textFlow.getFirstLeaf() as SpanElement;

            para.text += " وثيقة إثبات صلة القرابة مصدقة من سفارة دولة الإمارات – إذا لم يكن اسم المكفول مدرجاً في جواز سفر";

            textFlow.flowComposer.updateAllControllers();

        }

    }

}

Thanks, yes I did try it without calling setCompositionSize but somehow it had undesired results. The code as it stands comes closest to what I need. It may not be pretty but it seems to work :-)
