Adobe FLEX 2-MIGRATING APPLICATIONS TO FLEX 2 Manual page 107

The Flex compiler automatically generates an event named
properties so the properties can be used as the source of a data binding expression. In this case,
specifying the
[Bindable]
[Bindable(event="propertyChange")]
Binding from a single property
To make a single property usable as the source for a data binding expression, add the
metadata tag before the property declaration. The property can be public,
[Bindable]
protected, or private.
Flex 1.5:
var foo:String; // You could bind to this in 1.5
Flex 2:
[Bindable]
public var foo:String;

specifying the
[Bindable]
[Bindable(event="propertyChange")]
Binding from a property defined by a setter and getter
method
In Flex 1.5, you used the
replace the
[ChangeEvent]
event in the method. This strategy also applies to other methods that dispatched custom
events.
Flex 1.5:
[ChangeEvent("maxFontSizeChanged")]
// Define public getter method.
public function get maxFontSize():Number {
return _maxFontSize;
}
Flex 2:
[Bindable(event="maxFontSizeChanged")]
// Define public getter method.
public function get maxFontSize():Number {
return _maxFontSize;
}
