Bindable Class / property setter

[cesaric]

Bindable Class VO's don't hit the setters for certain data types. For example, Boolean type will return "false" on undefined preventing us from setting the private member to false. See #2 at http://livedocs.adobe.com/flex/3/html/help.html?content=Part4_data_access_1.html

We can fix this by explicitly adding Bindable event in these special cases:

[Bindable("propertyChanged")]
public function get isAdmin():Boolean
{
return _isAdmin;
}

public function set isAdmin(value:Boolean):void
{
_isAdmin = value;
this.dispatchEvent(new Event("propertyChanged"));
}
