We've been using NHibernate 1.0 wrap in a couple classes so it can be stored in HTTPContext. We also run under .Net 2.0.
We were using is fine for month until we release to production. Every couple of days we start getting "incorrect syntax near" exceptions. Once the exceptions begin we have to do an IIS Reset to clear them. The full query is contained below but I'll pull out the faulty snippet here:
explicitmo0_.EnterpriseUserID as 3_1016789_1_,
explicitmo0_.EnterpriseModuleID as 2_1016789_1_,
As you see the alias are missing the fragment column name and they begin with a number.
Any help on this would be greatly appreciated.
