Well, couldn't it be reclassified as a bug fix? Not being able to navigate associations because of a hard coded "this" in the construction of the order by seems like something many people would face. I could be wrong.
Anyway this patch has been around a long time and as far as I can tell was submitted properly. More importantly H3 is not even released and support for it in Spring is even farther off. Any reason 2.1 is being abandoned so soon? I'm not asking for another 2.1 release. I don't see the harm in applying it to 2.1 CVS head but maybe I'm short-sighted. > -----Original Message----- > From: Emmanuel Bernard [mailto:[EMAIL PROTECTED] > Sent: Wednesday, September 29, 2004 12:59 PM > To: March, Andres > Cc: William Draï; Emmanuel Bernard; [EMAIL PROTECTED] > Subject: Re: [Hibernate] Polymorphic queries, where and order by > > Sorry, no new feature will be added to the 2.1 branch. > > March, Andres wrote: > > > We can't use H3 unfortunately because we do not have enough time to > > add H3 support to Spring.
