Nhibernate 3.1 and many-to-one laziness no-proxy

[Rico]

Hi, is there any known trouble about Nhibernate 3.1 and no-proxy
laziness?
I moved from Nhibernate 2.1.2.4000 to 3.1.4000 and with a mapping like
this one:

<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
namespace="myNamespace" assembly="myAssembly">
<class name="Comment" table="comments_tb">
<id name="Id" column="idComment" unsaved-value="0">
<generator class="native" />
</id>
<property name="isEnabled" column="isEnabled" access="field"/>
<many-to-one name="Post" lazy="no-proxy"/>
</class>
</hibernate-mapping>

When I try
session.CreateCriteria(myClassMetaData.Value.GetMappedClass(EntityMode.Poco)).SetMaxResults(1).List()
i get NHibernate.Exceptions.GenericADOException: could not execute
query
[...the query...]
---> System.NotSupportedException: Specified method is not supported.

stacktrace:

resultTypes)
NHibernate.Impl.SessionImpl.List(CriteriaImpl criteria, IList results)
NHibernate.Impl.CriteriaImpl.List(IList results)
NHibernate.Impl.CriteriaImpl.List()

With Nh version 2.1.2.4000 it worked fine and I've noticed that
changing the laziness attribute there aren't any issues and it looks
like related to Linfu bytecode provider.
Any Idea?

Thanks in advance

in NH2.x lazy="no-proxy" is identical to lazy="false".

Since NH3 lazy="no-proxy" has a specific meaning.

You have to fix your mapping using lazy="false" 

[Rico]

Thanks you for the answer, my goal is to use the no-proxy feature
without get the 'NotSupportedException' from Linfu. I was wondering if
use a different byteCode provider, could it be a solution?

[Fabio Maulo]

For NH3.0 and NH3.1 you can use Castle.

[Rico]

Castle implementation looks like to work, does it mean that Linfu
doesn't support NH 3.0 and over for now?

[Berke Sokhan]

AFAIK, they merged LinFu to NH3.2 binary and get rid of any other runtime proxy providers. So you wont be needing "Required_For_LazyLoading" dlls from NH 3.2 on..
