I've got a weird issue I can't find a solution for: using a list view for linked records in interface designer. I have a record list to choose from Table A, with a linked record to table B. I can display that linked record field to show a list of items from Table B, that works great! But if I try to use that list view as a two level view to group those items, it gives me the error:
"Unable to use non-table source in this context" and shows nothing. I think this is saying that the interface essentially doesn't have the data I'm trying to use, but I have no way to resolve it sadly, and changing which levels are used doesn't make any difference
