For sure, textChanged will be false by the time you get back from
super.commitProperties so I think I'd check the text before calling
super.commitProperties and change it to the default if needed.

Hi, all.

I'm extending TextArea to make it show default text if it's empty. It will
be cleared (if needed) on focusIn.
The problem I've faced is that when I set text property in
commitProperties method that text isn't shown in the TextArea itself. :\

Following is my class:

package {

import flash.display.DisplayObject;
import flash.events.FocusEvent;

import mx.controls.TextArea;

public class ExtendedTextArea extends TextArea {

public function get defaultText() : String {
return _defaultText;
}

public function set defaultText(value : String) : void {
_defaultText = value;
_defaultTextChanged = true;
invalidateProperties();
}

public function get defaultTextFunctional() : Boolean {
return _defaultTextFunctional;
}

public function set defaultTextFunctional(value : Boolean) : void
{
_defaultTextFunctional = value;
}

override public function get text() : String {
if (_showingDefaultText) {
return ;
} else {
return super.text;
}
}

override public function set text(value : String) : void {
super.text = value;
_textChanged = true;
invalidateProperties();
}

override protected function commitProperties() : void {
super.commitProperties ();

if ((_textChanged || _defaultTextChanged)  text == ) {
setText(_defaultText, true);
}

_textChanged = false;
_defaultTextChanged = false;
}

override protected function focusInHandler(event : FocusEvent) :
void {
super.focusInHandler(event);
if (contains(DisplayObject( event.target)) 
_showingDefaultText  !_defaultTextFunctional) {
setText();
}
}

override protected function focusOutHandler(event : FocusEvent) :
void {
super.focusOutHandler(event);
if (contains(DisplayObject(event.target)) 
!_defaultTextFunctional  text == ) {
setText(_defaultText, true);
}
}

private function setText(value : String, isDefaultText : Boolean =
false) : void {
text = value;
_showingDefaultText = isDefaultText;
}

private var _defaultText : String = ;

private var _defaultTextChanged : Boolean;

private var _textChanged : Boolean;

private var _showingDefaultText : Boolean;

private var _defaultTextFunctional : Boolean;

}

}

The class is far from complete.
Here's sample application:

?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=vertical
ExtendedTextArea
width=220
height=80
defaultText=Album description goes here...
/
mx:Button label=button /
/mx:Application

Can anyone explain me this behavior and/or where is my mistake?

Thanks,
