If you integrate a View with exposed filters (for user defined searches) into a Panel page, that View has to return something right off the bat just to show up in the Panel. And you can’t give it a header or a footer either. Completely weird. What i did was supply a keyword in the “body” filter – “sample”. The word sample returns exactly one result for me. That’s just the nature of my content. But this allows the View to show up and isn’t too ambiguous to the user as to what they should do next.
