Between each effect there is a flicker when the next effect started.
I try to use flex3.4 but the problem is still there. I really confused ~~
<s:Application ..
transitions="{[bm_tran]}" >
<s:states>
<s:State name="state1" />
<s:State name="state2" />
</s:states>
<fx:Declarations>
<s:Transition id="bm_tran">
<s:Sequence target="{bitmapimage1}" duration="500">
<s:Resize />
<s:Pause/> <!-- seem isn't available -->
<s:CrossFade />
</s:Sequence>
</s:Transition>
</fx:Declarations>
<s:BitmapImage height.state2="113" height.state1="149" id="bitmapimage1"
source.state2="@Embed('Image_0002.png')"
source.state1="@Embed('Image_0001.png')"
width="429" />
<s:Button label="Click Me!" click="{currentState = (currentState == 'state1')
? 'state2':'state1';}"/>
