I'm setting up a "Wizard" using force.com sites. I'm implementing this with visualforce and apex.

The page allows a user to submit information which creates an opportunity, and then takes them to a second page that allows them to create objects for quotation which are child objects to opportunity, or attach files to the opportunity.

When the user finishes, they are taken to a page that displays their information back to them. I am displaying a related list of the child objects they have created, and a related list of all attachments. I also give them the ability to go back and edit the items they have entered.

The problem is that if a user edits an item and then returns to the confirmation page, the related list of objects and attachments does not update. New items they create dont show up, and changes they have made aren't reflected on the related list. If I click the refresh button, then the changes will be reflected, so on the database end of it, the DML is happening, but the changes are not reflected on the sites page. All of my methods setRedirect(true) before returning pageReferences. In addition, this problem does NOT happen if I access the site from within Salesforce. If I log in and view the wizard, the information refreshes with absolutely no problems, it is only when viewing it externally via sites that the issue occurs

I'll post my code below. Any help would be greatly appreciated.

}//end class
