Transitions work just fine in flex4, but you need to declare them in a
<transitions> block (just like in flex3), not in the Declarations block:
<s:transitions>
<s:Transition fromState=”primary” toState=”secondary”>
<s:Sequence targets=”{[panel1]}”>
// etc.
Note that Blur is not an effect in Flex4, but it should work fine as long as
you target a component (flex3 effects don’t work on graphic elements, which is
one of the reasons for the new flex4 effects). To get a flex4 effect that runs
a blur, use AnimateFilter with a BlurFilter specified as the filter you are
animating.

Subject: [flexcoders] About effect in Flex4
When I clicked the button to change state,but the transition effect doesn't
work.
I wonder if the transition is still available in Flex4?
