Question

As per my observation this does not work in flex4:

<mx:TextArea id="taMytext" text="\n hi\n san"/> //use of \n does not work here
<s:Button label="Click it" click="Myfun()" />

Using script it’s possible:

public function Myfun():void
            {
                taMytext.text="hi\n";
                taMytext.text+="san";
            }

Answer 1

It seems the only way is to use the following:

<mx:TextArea horizontalCenter="0" id="taMytext" text="{'\n'} hi{'\n'} san" verticalCenter="0" />
