Setup requirements
=====================
create follwoing VF pages and controller
Visualforce Page- case3
=======================
<apex:page standardController="Case" extensions="CaseExtension" showHeader="false">

</apex:pageBlockSection>
</apex:pageBlock>
</apex:page>
Controller-
=================
public class CaseExtension{
public Case c;
public CaseExtension(ApexPages.StandardController stdController) {
c = (Case)stdController.getRecord();
}
public PageReference nextPage() {
Attachment att = New Attachment(Name = 'Test.pdf');
att.parentId = c.Id;
PageReference pdf = new PageReference('/apex/Case2?id=' + c.Id);
//PageReference pdf = new PageReference('/apex/Case2?id=' + c.Id); //NOT working
//WORKAROUND
/* PageReference pdf = Page.case2;
pdf.getParameters().put('id',c.Id);*/
att.Body = pdf.getContentAsPDF();
insert att;
system.debug('attachment inserted');
return new PageReference('/' + att.Id);
}
}

1. Login as any User
2. Navigate to the following link - <salesforce instance>/apex/case1?id=<caseid>
3. Click on 'Build PDF' button.
4. You get error- “The page you submitted was invalid for your session. Please click Save again to confirm your change.”
5. change the controller -
Comment out line 12 and uncomment line 15 and 16 and test again
6. It works fine
Workaround
Workaround
-Using Page.existingPageName instead of PageReference ('partialURL'). (As mentioned in steps to replicate )
The documentation also mentions in PageReference to use Page.existingPageName
“This syntax is less preferable for referencing other Visualforce pages than Page.existingPageName because the PageReference is constructed at runtime, rather than referenced at compile time. Runtime references are not available to the referential integrity system. Consequently, the platform doesn't recognize that this controller or controller extension is dependent on the existence of the specified page and won't issue an error message to prevent user deletion of the page.”
