[Opensource] workflow using addStatePairing - not quite getting it

[Helga Wyns]

Yes, this time I'm sure (sorry for my misleading suggestion before). In the 
perform method of my state I call the setFormCache() method (this method is 
defined in the State class, and it populates the form).
Like I said, I don't know if this is a good way to handle things, but 
anyway, it seems to work for my application and it's easy.
