copied!<p>First - you doing infinite loop in event listener! Your code in event handler invokes it selves! TLF.text = VALUE produce event like TLF.dispatch(new Event(Event.CHANGE));</p> <p>So <strong>add event listener to user actions not text change!</strong> E.g. for KEY_UP</p> <p>Second - correct formatting code so it will be applied to new text:</p> <pre><code>myTLFTextField.text = NEW_VALUE; myTextFlow = myTLFTextField.textFlow; myTextFlow.hostFormat = myFormat; </code></pre> <p>Edit: For more clarity I add full code:</p> <pre><code>import fl.text.TLFTextField; import flashx.textLayout.formats.TextLayoutFormat; import flashx.textLayout.elements.TextFlow; import flash.events.KeyboardEvent; var myTLFTextField:TLFTextField = new TLFTextField(); addChild(myTLFTextField); myTLFTextField.x = 10; myTLFTextField.y = 10; myTLFTextField.width = 400; myTLFTextField.height = 100; myTLFTextField.text = "This is my text"; myTLFTextField.type = "input"; //allow user to wirte in filed var myFormat:TextLayoutFormat = new TextLayoutFormat(); myFormat.textIndent = 8; myFormat.color = 0x336633; myFormat.fontFamily = "Arial, Helvetica, _sans"; myFormat.fontSize = 24; var myTextFlow:TextFlow = myTLFTextField.textFlow; myTextFlow.hostFormat = myFormat; myTextFlow.flowComposer.updateAllControllers(); //--; myTLFTextField.addEventListener(Event.CHANGE, wrongHandler); myTLFTextField.addEventListener(KeyboardEvent.KEY_UP, goodHandler); myTLFTextField.text = 'TEXT'; //this invoke CHANGE and trace '-' in console setTimeout(function(){ myTLFTextField.text = 'text';}, 500); //this invoke CHANGE and trace '-' in console function wrongHandler(event:Event):void { //myTLFTextField.text = myTLFTextField.text.toUpperCase(); //myTextFlow = myTLFTextField.textFlow; //myTextFlow.hostFormat = myFormat; // above code will run infinity loop of changing text! test it by uncomment and comment KEY_UP listener! trace('-'); // to see in console when and how many event was triggered } function goodHandler(event:Event):void { myTLFTextField.text = myTLFTextField.text.toUpperCase(); myTextFlow = myTLFTextField.textFlow; // reasign formating myTextFlow.hostFormat = myFormat; var i:uint = myTLFTextField.text.length; myTLFTextField.setSelection(i,i); // move carret to last sign trace('+'); // to see in console when and how many event was triggered } </code></pre> <p>Output:</p> <ol> <li>-</li> <li>-</li> </ol> <p>Output after writing 'a' character in field:</p> <ol> <li>-</li> <li>-</li> <li>-</li> <li>-</li> <li>+</li> <li>-</li> </ol> <p>Result on stage: TEXTA</p>
