My project is dependant upon another project. But, my tests are failing because of some class in the dependant project(this project's tests are running fine) with the following error:

Test 'sometest' failed: FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

----> FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

----> FluentNHibernate.Visitors.AmbiguousComponentReferenceException : Multiple external components for 'CInformation', referenced from property 'ACInformation' of 'AC', unable to continue.

Any ideas appreciated. Thanks!!

   It's saying that when resolving the mapping for the ACInformation property
   it's finding multiple definitions and doesn't know what to do. You either
   have multiple ComponentMap<CInformation>'s defined, or you're registering
   the same one multiple times with FNH.

   Thank you for the quick reply Mr.Gregory. I made sure that Im not doing multiple mappings. What is Registering with Fluent NHibernate mean? You mean in TestFixtureBase Class??

   Yes, wherever you're using Fluently.Configure is where you're registering
   your mappings with Fluent NHibernate. Show us the code and we might be able
   to be more helpful.

   Sorry, I cant put out the code here. But, here's how i have my mappings ::
   Person is a project with folders Name and Location
   In my mappings I have
   m.FluentMappings.AddFromAssemblyOf()

                       .Conventions.Add(new IdConvention())
                       .Conventions.Add(new TableNameConvention());

   m.FluentMappings.AddFromAssemblyOf();

   I think this is where I am configuring the same project 2 times. is there any way that i can configure "each class" in Location separately ?

   Never Mind, I used Map instead of References in the Mapping. But, the error i was getting was so misleading.
