Re: NHibernate proxies losing  exceptions...

Isn't it because code that uses the exceptions for business logic might need to rely on the original exception type?

E.g., the client might rely on getting specific exceptions like ...

try

{

DomainModel.CreateBanana("banana name", "banana description");

}

catch(DuplicateBananaException dbne)

{

MessageBox("There is already a banana called " + dbne.DuplicateBanana.Name);

}

Is there any reason to go with this approach over simply throwing a HibernateException() with this as the inner exception?

Hi,

I originally posted in the forum, and was asked to repost to the mailing list:

http://forum.hibernate.org/viewtopic.php?t=983176

I've attached a patch that keeps the exception stack-trace after an exception is re-thrown from a proxy.

The patch can also be downloaded from: http://freespace.virgin.net/richard.brown0308/NHibernateExceptionStack.patch

Could someone take a look and see if they think it is worth applying the patch to NHibernate?

Thanks,
Richard
