I am trying to create an online student application. The application is quite lengthy, so ideally I want to break it up into multiple pages, using a "next" button. Also, while most of the info is on the student record (PersonAccount), some info goes into custom objs with a master-detail relationship to the student record.

I was hoping to do this with cmsForce2, but it looks like this is too complicated for that. If anyone knows a good app or tool to do this, I would love to know. Barring that, I am assuming I am going to have to create custom Visualforce pages with custom controllers.

Now I have some experience creating Visualforce pages and writing some apex triggers, but nothing on this scale.

So, how would I

1. submit the first page to the PersonAccount (all fields are on the Contact side), retrieve the id and send it as a hidden field to the 2nd page? Would I just extend the Contact controller or do I need to write something new from scratch?

2. submit to the custom objs?

3. If the applicant quits in the middle, to rollback the changes as we do not want a half filled out application?

Thanks for speedy answers to any or all of the above mentioned questions and any other advice anyone can give.
