Adobe FLEX 2-MIGRATING APPLICATIONS TO FLEX 2 Manual page 132

Use binding in MXML to specify the effect
In Flex 1.5, you assigned the effect to an effect trigger property with no data binding:
<mx:Button id="myButton" creationCompleteEffect="myWL"/>
<mx:Button id="myOtherButton" creationCompleteEffect="myWL"/>
In Flex 2, you use data binding to assign an effect to a target:
<mx:Button id="myButton" creationCompleteEffect="{myWL}"/>
<mx:Button id="myOtherButton" creationCompleteEffect="{myWL}"/>
The show property is now the showTarget property
You now use the property with effects, instead of the
MaskEffect.showTarget
property:
MaskEffect.show
Flex 1.5:
<mx:WipeUp id="wipeup" duration="1000" show="true"/>
Flex 2:
<mx:WipeUp id="wipeup" duration="1000" showTarget="true"/>
