Creating a custom creation complete effect on a Flex Alert control (redux)

In a previous example, “Creating a custom creation complete effect on a Flex Alert control”, we saw how you could specify an effect which gets played when an Alert control is displayed by setting the Alert control’s creationCompleteEffect style.

The following example shows how you can apply a parallel Fade/Move effect when the Alert control is created by setting the the creationCompleteEffect effect/style in MXML and ActionScript.
