I've got a portal inside a tab panel; in fact, I've got multiple tab panels each with one or more portals on the panel. I've got a single relationship that displays just fields with no values whatsoever. After messing with this for an hour, I deleted the specific tab panel, added a new one and put the portal and fields back on the new panel. Went into Browse mode and everything displayed correctly until I went to another tab panel and came back and now the same thing is happening. Has anybody seen this before or any ideas what might be causing it?
