[Opensource] workflow using addStatePairing - not quite getti ng it

[Gene McCullough]

I am experiencing the same thing.  I get to my validation state, and the 
form has been reset (my values are what I've defined in the 
resetController() method).  Same thing when I get to the Final state.  I've 
seen no examples or indications of how to access the controller form data 
(except that one code snippet renamed the object reference to 
controllerForm instead of stateForm in the final state) as opposed to the 
state form data.

hope someone can help, and thanks in advance
