Crossposting from Visual Workflow for greater visibility:

I have created 2 VFPs to house 2 different visual workflows and instead of refreshing the entire page on each 'Next', I have used rerender to update just the flow's output panel.  What I'm struggling with is that on Finish, I want the to reload the source record (a Case), but since it wants to rerender in the output panel, I receive an error that "This content cannot be displayed in a frame.".  How can I get it to rerender the frame during the flow, but reload the entire page after the flow (instead of the flow looping back to the beginning.
