I have the following configuration to set NH and Envers up:
var properties = new Dictionary<string, string>();
properties[NHibernate.Cfg.Environment.Dialect] = "NHibernate.Dialect.MsSql2008Dialect";
properties[NHibernate.Cfg.Environment.ConnectionDriver] = "NHibernate.Driver.SqlClientDriver";
properties[NHibernate.Cfg.Environment.Hbm2ddlAuto] = "update";
properties[NHibernate.Cfg.Environment.FormatSql] = "true";
properties[NHibernate.Cfg.Environment.ShowSql] = "true";
properties[NHibernate.Cfg.Environment.ConnectionString] = "Data Source=localhost;Initial Catalog=OU_KASH;Integrated Security=True;Asynchronous Processing=true";
var cfg = new Configuration();
cfg.Configure()
.SetProperties(properties)
.AddAssembly(typeof(AliasTb).Assembly.FullName)
;
cfg.SetEnversProperty(ConfigurationKey.StoreDataAtDelete, true);
cfg.SetEnversProperty(ConfigurationKey.AuditStrategy, typeof(NHibernate.Envers.Strategy.ValidityAuditStrategy));
cfg.SetEnversProperty(ConfigurationKey.TrackEntitiesChangedInRevision, true);
cfg.SetEnversProperty(ConfigurationKey.GlobalWithModifiedFlag, true);
cfg.IntegrateWithEnvers(new AttributeConfiguration());
var factory = cfg.BuildSessionFactory();
If I leave off the
cfg.SetEnversProperty(ConfigurationKey.AuditStrategy, typeof(NHibernate.Envers.Strategy.ValidityAuditStrategy));
it works fine, but with that option I get the following exception when I commit my transaction (which updates a CompanyAddressTb object):
ERROR NHibernate.AssertionFailure - An AssertionFailure occurred - this may indicate a bug in NHibernate or in your custom types.
System.InvalidOperationException: Cannot find previous revision for entity NhDoodling.Entities.Domain.CompanyAddressTb_AUD and id 12962904

Any help will be greatly appreciated.
