I've gotten around trying 1177 now, and the definition of the relationship does
not break inheritance. But when trying to operate the data-model I now get:
line 286, in visit_select
orderby = "%s.rowid ASC" % select.froms[0].name
AttributeError: 'JoinMarker' object has no attribute 'name'
which was working as well in 1117. Below the full traceback.
