I have posted a while ago the way I have solved this:
You create your own MyAlpha class subclass of Alpha where you can actually
set the resulting return value
This way you have full control!!!!
very easi and efficient

Hi,
I think the problem is that an Alpha object cannot be paused. I solved this
problem by detaching the Behavior so that it becomes inactive and read the
protected members lowerKnot and upperKnot and read the TransformGroup´s
Transform3D of the Behavior. To restart the Behavior I recreate the whole
thing starting with the stored values of the Transform3D and the rest of the
animation data starting with lowerKnot. Then I reatched the Behavior.
I know this is not the best solution but maybe someone has a better idea,
like usinf an Alpha Object with pause-function.
Marco.
