I hope this isn't a dup, I can't seem to find it if it is. I have an inline VF page in a standard account detail page. A button in my VF page does a pagereference redirect to another (managed) VF page. I have to specify "_top" as my target in my form tag to get to the parent container, but the second VF page shows without the header and sidebar, because I'm calling it with a URL directly.
Are there any parameters that I could add to my URL to make the second page open WITH sidebar and headers as if I were calling the second page from a standard SFDC page?
Thanks in advance.
