All,
I'm getting a weird problem - I'm doing the following call:
ILocation loc = Session.Get<Location>(id);
and NH is throwing this error:
Exception Unable to cast object of type
'INHibernateProxyProxy2183142372c34751a1aceee41a501ee3' to type
'Intellident.Core.Domains.Location'.
at NHibernate.Impl.SessionImpl.Get[T](Object id)
at Intellident.Core.Repository.NHibernate.NHibernateRepository.Get
[T](Guid key) in ...
There are no proxies involved in this. This seems to happen in a
certain situation with data but I can't narrow it down yet. How can I
be getting a proxy error with this anyway... no proxies are involved
for this type of call surely?
I'd try a Get<ILocation> but NH doesn't let me do that with themapping
below as I get a "no persister" exception. I can add to the mapping
(e.g. some kind of alias ?) but I can't replace the class
name-"Location" with "ILocation".
Mapping file for location:
