[Opensource] best use of framework, transitioning

[Gene]

I'd like some advice if anyone has any.

I've got one controller-state that needs to switch control to another 
controller-state.  I can make that happen with following code:

MyController mycontroller = new MyController();
Transition newTrans = new Transition("addWizard","stringhere", 
mycontroller.getClass() ,"promptAppeal");
newTrans.transition(request,response);

however, all of my parameters in the request object disappear.  Can I make 
them not disappear easily.  Do I need to allocate control to another 
controller differently?
Am I missing the point of Transitions all together?

Any help appreciated.

TIA
