TFL getEventMirror

OK, so I changed my SDK to Hero and also realized that EventMirrors do not work when textFlow is binded (I used to had a actual flow that I was manipulating and had it binded to the textFlow property of a RichEditable Text. Nw after I changed the code to take care of these issues, I have the even fire, but not always!

This is wiered! Also, more wierd is that the event which is a FlowMouseEvent does not consistently contain the stuff it should have (like the flowElement or the originalMouseEvent... sigh...

My code is rather big, but the part that matters is as follows:

                    var ayaSpan:SpanElement = new SpanElement();
                    ayaSpan.text = aya.@text;
                    var mirror1:IEventDispatcher = ayaSpan.getEventMirror();
                    mirror1.addEventListener(FlowElementMouseEvent.CLICK, toggleTextBG);
                   
                    var ayaNumSpan:SpanElement = new SpanElement();
                    ayaNumSpan.text = '   ﴿'+arbicNums(aya.@index)+'﴾';
                    ayaNumSpan.breakOpportunity=BreakOpportunity.NONE;
                    var mirror2:IEventDispatcher = ayaNumSpan.getEventMirror();
                    mirror2.addEventListener(FlowElementMouseEvent.CLICK, toggleTextBG);
                   
                    //var ayaSP:SubParagraphGroupElement=new SubParagraphGroupElement();
                    //ayaSP.replaceChildren(0,0,ayaSpan,ayaNumSpan);
                    //ayaSP.addChild(ayaSpan);
                    //ayaSP.addChild(ayaNumSpan);
                   
                    var ayaPara:ParagraphElement = new ParagraphElement();
                    ayaPara.addChild(ayaSpan);
                    ayaPara.addChild(ayaNumSpan);
                    //ayaPara.addChild(ayaSP);
                    mainText.textFlow.addChild(ayaPara);

            public function toggleTextBG(e:FlowElementMouseEvent):void{
                trace("Flow even fired-- ");
                if(e.flowElement==null)trace("Null flow element!");
                else {
                    trace(e.flowElement.getParagraph().getText(0));
                    //e.flowElement.getParagraph().fontWeight="bold"; even this simple thing sometimes throws an exception!
                }

One side thing, as I saw it is encouraged by TFL group, as you see, I have tried SubParagraphGroupElement too with no luck. In fact it always fires an exception when I use it. BTW, I used replaceChildren as in the exmaples with the smae results...
