I get the following error when attempting to parse this schema (produced using Mapping.Attributes):Cannot extend unmapped class: nhibernate2test.BLL.Tank

Here is the stack trace:

Probably a dumb suggestion, but did you try moving nhibernate2test.BLL.Tank declaration above nhibernate2test.BLL.AerobicTank?

I tried that and it worked. The problem is that I'm using the mapping attributes in NHibernateContrib and that's the way it serializes the schema at runtime. Does anyone know any way to ensure that the serializer serializes the subclasses in the right order? I've tried using the order field in the subclass attribute and that doesn't seem to affect the order. However I would have thought that the serializer would be able to infer the correct order without requiring any extra information by following the subclass definitions up the chain.

Feel free to create a JIRA issue: http://jira.nhibernate.org/
I will try to add this improvement.

I'd love to but that link doesn't work. Do you have an alternate solution?

Thanks very much for this very useful software. Despite the bug it has made my life much easier.

I don't know why you can't access this website... It is working for me. You may try again.

Anyway, your issue is already solved :)
Cf. http://jira.nhibernate.org/browse/NH-652
Can you check out the SVN version of NHibernate and try it to see if it really works?

Hi! I know this topic is old, but I thought about letting some info for people whom, like me, stumbles into such problem.
Well, I'm still using NHibernate 1.0.2.0 and I can see from NH-652 that it was solved for 1.2.0Beta1, not an option at the moment. Nevertheless, I found a easy workaround for 1.0.2: the order of loading can be controlled by the name of the source file containing the class. I prefixed my source file name with an "01" making it the "first" in the assembly and that corrected the problem, I'm using Visual Studio 2005.

Note that NHibernate.Mapping.Attributes can be easily back-ported to NH1.0.2. All you have to do is:
- Copy nhibernate-mapping-2.0.xsd from \nhibernate\src\NHibernate\ to \nhibernate\src\NHibernate.Mapping.Attributes\
- Open the solution: NHibernate.Mapping.Attributes.Generator-2.0.sln
- In NHibernate.Mapping.Attributes project, remove the file nhibernate-mapping.xsd and add nhibernate-mapping-2.0.xsd (+ make it "EmbeddedRessource")
- Search for "nhibernate-mapping.xsd" in all files and replace it by "nhibernate-mapping-2.0.xsd"
- Run the Generator project
- Compile NHibernate.Mapping.Attributes and use it.
Voilà ! :)
