Chris,
I am trying to get my hands around your code. I see the function which loops until there are no more input violations and although I have a guess about the response, I would still like to hear from you on these questions:
Where would you place calls to the backend which for example pull data from a database to populate the bean for the next page? Where would if place logic which decides what is the next page based on input choices made on the current page?
-=Ivelin=-
Below is a variation of the feedback wizard example that should answer your questions. Where you see
print("handling xxxxx")
that is where you would perform back-end actions like reading from a database, as well as where you would decide which page to send next based on the values set in the bean by the previous page. The contrived example below shows the deployment and system pages in reverse order if the "age" you enter in the userIdentity page is greater than 20.
Regards,
Chris
