From af44efe26e3f703ca1c30e79ee68428eed35abcf Mon Sep 17 00:00:00 2001 From: Mike Bayer Date: Sat, 2 Feb 2013 20:06:31 -0500 Subject: Fixed a bug regarding column annotations which in particular could impact some usages of the new :func:`.orm.remote` and :func:`.orm.local` annotation functions, where annotations could be lost when the column were used in a subsequent expression.
