Behaviors

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 

MaskEffect.showTarget

 property with effects, instead of the 

MaskEffect.show

 property:

Flex 1.5:

<mx:WipeUp id="wipeup" duration="1000" show="true"/>

Flex 2:

<mx:WipeUp id="wipeup" duration="1000" showTarget="true"/>

New properties added for the Zoom effect

The Zoom effect has new properties for Flex 2. The 

zoomTo

zoomHeightTo

 and 

zoomWidthTo

, and the 

zoomFrom

 property has been changed to 

zoomHeightFrom

 and

. 

Also two more properties have been added to the Zoom effect: 

originX, originY

Specify the x-position and y-position of the origin, or registration point, of 

the zoom. The default value is the coordinates of the center of the effect target.
