Yeah, I always find it easier to build a Seaside UI to something than a
Morphic UI.

The immediate problem is that your "step" instance variable (sorry, not
sure what it's called, don't have the code in front of me) doesn't
backtrack its state.  You should put it in a StateHolder.

However, the problem would also be solved if you used control flow to
manage your position in the wizard.  The way I personally would implement
it is:

- get rid of the "Previous" button, that's what the back button is for
- create a Component for each step, that is initialized with whatever info
it needs, and #answers the data provided.
- Have an initial page with one #run method that looks like

info1 := self call: (Step1 new).
info2 := self call: (Step2 new).
info3 := self call: (Step3 new).

etc.

I'll have to look at that when I have access to the code.

No, it's not yet.  I brought the code over from Seaside1 but haven't
actually made it work.  That's why it's in the "Alpha" category :).
