Problem playing parallel effects - apache-flex

Question

I could not play the parallel effect which is defined by the following code:
var parallel:Parallel=new Parallel();
var E1:WipeDown=new WipeDown();
var E2:WipeLeft=new WipeLeft();
parallel.addChild(E2);
parallel.addChild(E1);
parallel.duration=2000;
parallel.target=this;
parallel.play();
On playin the effect by calling effect() function only the effect E1 is getting played.
If the code was:
parallel.addChild(E1);
parallel.addChild(E2);
instead of:
parallel.addChild(E2);
parallel.addChild(E1);
then only the effect E2 is getting played..
To summurize only the top most child effect is getting played..
Can any one plese suggest a solution...
<code>
<mx:Parallel target="{this}" id="wipeDownLeft" duration="2000">
<mx:WipeDown target="{this}" duration="2000"/>
<mx:WipeLeft target="{this}" duration="2000"/>
</code>
If above code is not clear one can check with this application(copy the code and run)
code
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" minWidth="1024" minHeight="768" xmlns:ns1="*">
<mx:Canvas id="C" creationComplete="{E.play()}" width="50%" height="50%" backgroundColor="#387C44">
</mx:Canvas>
<mx:Parallel id="E" duration="2000">
<mx:WipeLeft duration="2000" target="{C}"/>
<mx:WipeDown duration="2000" target="{C}"/>
</mx:Parallel>
<mx:Button click="E.play([C])" x="{C.width+10}" y="{C.height+10}">
</mx:Button>
</mx:Application>

Answer 1

Maybe try setting the target property for each of the child effects instead?
Probably wouldnt hurt to do this for duration either...
I have only used effects in mxml, and this it how ive always done it (same with the doc examples?) - in fact have even done the dual wipe you are trying here, but not in AS...
[Edit] - I cannot see your mxml unlessI go into edit mode, but i cannot submit edits - use the code tags on it...
but same again, specify target and duration for the children not the parallel...

Answer 2

I think, the reason that, WipeLeft and WipeDown are mutually exclusive effects. But must performed in parallel. if you replace a to the , then it will be work. Or if you replace WipeLeft (or WipeDown) effect to some other effect, f.ex. , then it will be work too.
