I have a query with two levels of BOs, and grouped by the second-level BO. It runs fine as a query type. When I switch it to a graph (chart), the graph renders. But when I click on a part of the graph, the query returns no results.
It’s a custom BO for our ticketing system, and the second-level is to whom the ticket is assigned. Tickets can be assigned to more than one person, so they are associated people records, instead of hard-coded to the custom BO.
