I copied and pasted the code verbatim from the book, just to get something working quickly. The code examples are not Seam specific, just vanilla JSF, so I think something needs to be added or modified for Seam.
Could it be that the Wizard pages after the 1st one need to be excluded from the Seam servlet (or something like that) ?
I have exactly the same problem you have described above. Did anyone come up with a solution?
I have read the Katz book too and check out the forums (richfaces and seam)
