I’m working against the FNH trunk and NH 2.0.1. Funny thing is I am able to compile my mappings (via AutoPersistenceModel.CompileMappings) and write them to the file system successfully – FNH doesn’t complain. It is only when attempting to build the session factory that everything goes kaboom with the not very helpful error message above. Anyone got any ideas?

  1. Fluent NHibernate itself rarely complains at you directly. Internally it’s just building up your HBM files for you so if you told it to build something wrong then NHibernate proper will get grumpy.

    If you’re not already, you might want to start with exporting your mapping files like so:

    .Mappings(m => m.FluentMappings.AddFromAssemblyOf<MyClass>()     .ExportTo('path')

    Then you can dig around in there to see if something is wrong. I do recall getting this error once before and I think it relates to a mismatch in the number of columns mapped. It was one of those easy-to-miss errors in my mapping, so unfortunately all I can suggest is to really scour the output of ExportTo for anything that doesn’t make sense.
