Openlaszlo 5.0.x getattribute, rotation - openlaszlo

Question

I am working on an animation. I am using .swf pictures which I rotate with code like below.
My problem is: I want to read the actual rotation angel or position of the view "MoAuxid" when I klick on button "Abfrage". How can I get this result?
Best regards
Main Program:
<Mond width="400" height="400">
<view name="Bedienung_rot" x="800" y="10">
<simplelayout axis="y" inset="8"/>
<text text="Output:"/>
<edittext id="outputID" text = "0"/>
<text text="Arc:"/>
<edittext id="WinkelID" text = "51"/>
<button x="000" y="160">
Rotation
<!-- Handler to execute the Method -->
<handler name="onclick">
var x = WinkelID.getText();
MoAuxid.rotate(x);
outputID.setAttribute('text',x);
</handler>
</button>
<text text="Output2:"/>
<edittext id="output2ID" text = "x"/>
<button x="000" y="160">
Abfrage
<!-- Handler to execute the Method -->
<handler name="onclick">
var x = MoAuxid.getAttribute('y');
output2ID.setAttribute('text',x);
</handler>
</button>
</view>
</Mond>
