Hi, I have an application that requires the user to fill in some forms. The next form to serve up to the user depends on the contents of the last form. The transaction looks like this: user requests service: Zope starts up service Zope sends first page to the user User responds Zope decides what page to serve next Serves the page User responds ........repeat as needed Zope returns the result of the service request to the user. { for Zope read Bobo, I guess. I'm really interested in the long running Python process stuff, more than the delegation, roles etc at the moment. } I'm wondering how Zope would handle this. At the initial service request, Zope would return some html, but in some sense, it's really a function call OUT to the user to get some more data. the user then responds, but again, that's really a call to Zope. I would love to understand how Zope might work here... cheers and thanks for any help chris wright Dr. Christopher A.
