Hi. I'm getting an exception from this criteria:
var Crit = _Session.CreateCriteria<Application>()
.Add(Expression.IsNull("PersonID"))
.SetMaxResults(1000);
return Crit.List<Application>();
Here's the exception:
NHibernate.TypeMismatchException was unhandled by user code
Message="Provided id of the wrong type. Expected: System.Guid, got

InnerException:
I have an entity called Application. It has a string property called
PersonID. It also has a property FirstTerm which points to a Term entity.
Term has a guid ID property.
Please excuse the mapping. It is generated from FNH.

Any help would be greatly appreciated.
