Hi.

You can have a dedicated branch in the instance data (or a  whole model) for
each page in the wizard. Then you can make relevant only the branch that
corresponds to the particular step of the wizard. But this would require, of
course, that you copy the data you want to have at multiple pages from one
branch to another, and to collect them finally at one place for submitting
them.

We chose, instead, to extend XForms and to allow the "relevant" attribute
also on groups and other form controls. In case of a more comlicated wizard,
this would be probably a more suitable approach.

Hi there.

As I need to create some forms that need flexible use, I had a look at
XForms and am missing one feature (at least, it's not mentioned in the
XForms WD): Wizards.

I have searched the mailing list archives for that topic, only to find
others have asked about it, but there has not been a definitive answer.

So how are you supposed to build a Wizard? Shall all wizard pages reside in
one XForm document? Then how do you mark it as being a wizard? Which is the
start page, and how do you switch to subsequent pages? How do you ensure all
the pages operate with the same instance data?
