Salutations, I have found out the culprit. So first here is the code of the renderer :
<?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"; width="100%" styleName="myStyle1" verticalScrollPolicy="off" implements="mx.managers.IFocusManagerComponent" toolTip="{data.uid}" creationComplete="SentenceRendererCreationCompleteEventHandler()"> <mx:states> <mx:State name="BeingPlayed"> <mx:SetStyle target="{txtSentence}" name="color" value="#ff0000"/> </mx:State> <mx:State name="Selected"> <mx:SetProperty target="{txtSentence}" name="condenseWhite" value="false"/> <mx:SetEventHandler name="currentStateChange"> <mx:handler>SentenceRendererSelectedCurrentStateChangeEventHandler()</mx:handler> </mx:SetEventHandler> </mx:State> <mx:State name="HasBeenPlayed"> <mx:SetStyle target="{txtSentence}" name="color" value="#808080"/> <mx:SetStyle name="themeColor"/> </mx:State> </mx:states> <mx:Style source="Ressources/Librairie/USlicFont.css"/> <mx:TextArea id="txtSentence" wordWrap="true" width="90%" borderStyle="none" text="{data.Text}" textIndent="25" styleName="myStyle1" textDecoration="none" selectable="false" verticalScrollPolicy="off" minHeight="60"> </mx:TextArea> <mx:Button id="btnSentence" width="25" label="S{data.indexNo}" height="15" color="#ffffff"> <mx:downSkin>@Embed('Ressources/Librairie/History/Btn_S_D.swf')</mx:downSkin> <mx:overSkin>@Embed('Ressources/Librairie/History/Btn_S_U.swf')</mx:overSkin> <mx:upSkin>@Embed('Ressources/Librairie/History/Btn_S_U.swf')</mx:upSkin> </mx:Button> <mx:Script> <![CDATA[ import text.Highlighter; private var _Highlighter:Highlighter; private var _strDefaultState:String = "non"; override public function set data(value:Object):void { super.data = value; if(this.currentState == "Selected") { _Highlighter.reset(); _Highlighter.highlightText(); } } public function BeingPlayed():void { //Change the text color _strDefaultState = currentState; _Highlighter.reset(); this.currentState = "BeingPlayed"; } public function HasBeenPlayed():void { //Change the text color _Highlighter.reset(); this.currentState = "HasBeenPlayed"; } public function HasBeenSelected():void { this.currentState = "Selected"; } public function ResetRenderer():void { if(_strDefaultState != "non") { _Highlighter.reset(); currentState=_strDefaultState; _strDefaultState = "non"; } } public function BackToDefault():void { _Highlighter.reset(); currentState = ""; } private function getTextField(component:TextArea):TextField{ var len:int = component.numChildren; var r:TextField = new TextField(); for(var i:int=0; i<len; i++){ var thisChild:DisplayObject = component.getChildAt(i); if(thisChild is TextField){ var textChild:TextField = thisChild as TextField; r = textChild; } } return r; } private function SentenceRendererSelectedCurrentStateChangeEventHandler():void { _Highlighter.highlightText(); } private function SentenceRendererCreationCompleteEventHandler():void { _Highlighter = new Highlighter(getTextField(txtSentence),0xfffcee21); } ]]> </mx:Script> </mx:Canvas> The problem resides in the sub components Highlighter. This component draws a rectangle in the back of the text. (This is someone else's lib that I modified a bit) Anyway if I don't refer to this sub class at all then my application works fine. I believe I have to implements some Interface from Flex so that I can use this sub class in my Renderer...
