Ah, thanks. I wonder what the purpose of this subclass is and how
fragile this solution?

I'm not convinced I'm going to go the bindings route, as my source
list has non-collapsible groups, and making sure they're expanded and
not selected when the table is first displayed seems as much trouble
as just using a datasource in the first place!

Best wishes,
