That's isa MyAppDB::Tablename, not MyAppDB::TablenameResultset or whatever.

If it's an RS, call the variable $owners or $owner_rs. Trust me that this will
make your life easier.

The relationship must be returning an object, not a resultset then.
Don't confuse the Result (single object) and ResultSet (effectively a
virtual collection) objects. There's no reason you can't implement methods
on both but they are -not- the same thing.
This is why I religiously keep $owner versus $owner_rs coding conventions;
it makes it way easier to avoid getting confused :)
