After migration to new NHibernate version 1.2.0alpha

[Aleksei Kachanov]

Exception occured if we call
Type proxyType = typeBuilder.CreateType();
in Spring.Aop.Framework.DynamicProxy.CompositionProxy Builder

Signature of the body and declaration in a method implementation do not match. Type: 'Spring.Aop.DynamicProxy.Proxy_1ce2ebd366094bbc83e ac0220665567c'. Assembly: 'Spring.Aop.DynamicProxy, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

Hi Aleksei,

Can you try to get the type being proxied and interfaces it implements ?
(Add watch 'advised.TargetSource.TargetType')

It's maybe due to a method using ref/out paremeters or to a generic method.

It's bug is fully related to this issue http://forum.springframework.net/showthread.php?t=644
ISession and ISessionImplementor interfaces from NHibernate contains next method declarations


IList<T> Filter<T>( object collection, string filter, QueryParameters parameters );
IEnumerable<T> EnumerableFilter<T>( object collection, string filter, QueryParameters parameters );
T Get<T>( object id );
T Load<T>(object id, LockMode lockMode);


I hope this bug will be fixed as soon as "DynamicProxy doesn't support generic method declarations?" issue
Thanks, Bruno

Hi Aleksei,

I commited the fix for "DynamicProxy doesn't support generic method declarations".
Try the latest nightly build to see if it works now.

Hi Aleksei,

Any feedback from the migration to NHibernate 1.2alpha ?

After previous exception we stopped migration
I just integrate it and run some times. But didn't test and use.
At first look it works fine.
Thanks a lot.
I hope in the future we continue this integration.

I am using the latest NHibernate and the nightly build for Spring.Data.NHibernate with the file Spring.Data.NHibernate-20060824-1413.zip
When I try to call HibernateTemplate.Execute returning a generic IList, I received the following exception:


System.TypeLoadException: Signature of the body and declaration in a method implementation do not match. Type: 'Spring.Aop.DynamicProxy.Proxy_14e5932a031b4c9e8f5 32445c8ef9df5'. Assembly: 'Spring.Aop.DynamicProxy, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

As far I understood from your posts, this should've been fixed. Should this happen again or there is something else?

Hi Robert,

the proxy type name generated ("Spring.Aop.DynamicProxy.Proxy_14e5932a031b4c9e8f5 32445c8ef9df5'") tells me that you are not using fixed binaries (Spring.Aop & Spring.Core).
I updated (http://fisheye1.cenqua.com/changelog/springnet/?cs=MAIN:bbaia:20060810211513) the common libraries in NHibernate integration project after the fix.

Try with recent bins, and let me now,
Bruno

Thank you, works like a charm.
