Hello,
since last night we have a strange problem on loading an object instance by session.Get/Load (see below). It only occures for some dataobjects (DoWfInstance, DoWfNode).
Strangely for class DoWfNode but not for class DoWfTimerInstance which is derived from DoWfNode (see hbm)
As I know nothing relevant has changed(?), it's a big project with several developers...
Tasks I have already tried:
cleanup solution
rebuild all
delete solution
getting new from source safe
resetting of all references for nhibernate related dlls/projects (nhibernate, generics ...)
included nhibernate in debug mode: Error occures in NHibernate.Proxy.CastleProxyFactory#58:
_proxyGenerator.CreateClassProxy( _persistentClass, _interfaces, initializer, false );
Code:
/// <summary>
/// Build a proxy using the Castle.DynamicProxy library.
/// </summary>
/// <param name="id">The value for the Id.</param>
/// <param name="session">The Session the proxy is in.</param>
/// <returns>A fully built <c>INHibernateProxy</c>.</returns>
public INHibernateProxy GetProxy( object id, ISessionImplementor session )
{
try
{
CastleLazyInitializer initializer = new CastleLazyInitializer( _persistentClass, id,
_getIdentifierMethod, _setIdentifierMethod, session );
object generatedProxy = null;
if( IsClassProxy )
{
generatedProxy = _proxyGenerator.CreateClassProxy( _persistentClass, _interfaces, initializer, false ); // ERROR is raised here !!!
}
else
{
generatedProxy = _proxyGenerator.CreateProxy( _interfaces, initializer, new object() );
}
initializer._constructed = true;
return ( INHibernateProxy ) generatedProxy;
}
catch( Exception e )
{
log.Error( "Creating a proxy instance failed", e );
throw new HibernateException( "Creating a proxy instance failed", e );
}
}
