UPDATE : if I set Focus=true the text appears. I think that the text should be there even if I don't set focus.
This simple code when run in the device (Sony Tablet S) doesn't work as expected ... ( the text in the textbox dissapears, and if you change orientation appeears).
<?xml version="1.0" encoding="utf-8"?>
xmlns:s="library://ns.adobe.com/flex/spark" title="Editar acción"
xmlns:dao="dao.*" creationComplete="view1_creationCompleteHandler(event)" >
protected function view1_creationCompleteHandler(event:FlexEvent):void
txt1.setFocus(); // <---- if not set the text "Hola" flashes and dissapear.
<s:TextInput id="txt1" x="26" y="44"/>
Just for people who doesn't see other post, you can also apply the spark skin mobile to get it fixed (with some border effects, like softKeyboardType not working). More there : http://forums.adobe.com/thread/939250?tstart=0
Anyone knows if Adobe is addressing this bug?
