That would cause some kinds of joinedloads to render differently , which would impact how (+) comes out as well, but i wouldn’t think it would have the effect that the missing (+) is the only change, it would be more than that. So I have no better idea than you, so the method I’d do is just to git bisect (http://git-scm.com/docs/git-bisect) through revisions until you find the fix. If it’s a big merge revision, I can look into it to find something specific, but if you can get me a rev ID that would be a good start. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
