JMC-4653 found that some pages/tables were not filterable with the relevant attributes.
I think we should check if this concerns other pages/tables as well.

Some pages mix different event types, so the full page filter/flavor selector will not work with attributes only available in one of the event types, but in that case at least the relevant tables should be filterable.

• Class is a content type/attribute that can be shared between pages, could be relevant to select in one page and filter on another.
