NHibernate ignores the hbm.xml files

Question

I added a new table, .hbm.xml file and class to existing application. There is data from other tables as well displayed on the page.

For this new table data is not saved and displayed.

NHibernate ignores it. I don't get any error message. I also change the table value in the new hbm.xml file, but there is no error. But, if I change table in other files, application throws exception. Looks like it is not aware of the new file. I made this file as Embedded Resource. I'm using VS 2010, MVC and Oracle and C#

And here is the xml and class. Thanks in advance.

Answer 1

The similar issue as you, I have faced recently. And it was in VS 2012, where file re-naming works like, 1) selecting .hbm.xml file by clicking on it... 2) the part before file suffix is selected. 3) type new name, while suffix is unchanged.

The trick is that NHibernate files, embedded resources, have two suffixes: .hbm.xml. The configuration like this:

<mapping assembly="CaseMgr.Model" />

Works with convention: search embedded resources with the extension .hbm.xml. So, if your new file is

• MyNewFile.xml

It must be

• MyNewfile .hbm. xml

the missing .hbm was in my case the reason, why NHibernate did not know about that file at all, and no exception was thrown if it was wrong... but it was not loaded and not available

EXTENDED

If I get your scenario correctly: One VS project(library), many .hbm.xml files, all are embedded resources, all are working but one.

If I reproduce your issue correctly you should:

run IL Spy to check that the dll contains all expected embedded resources
run a test like:

var factory = ... //get your NHibernate factory
var entityType = typeof(CaseMgr.Model.BusinessObjects.PatLiverPeld);
var persister = factory.GetClassMetadata(entityType) as AbstractEntityPersister;
Assert.IsTrue(persister != null)

In case that you'll see resource, and there is NO persister... try to move your mapping to existing working file (two classes in one .hbm.xml file). Any other case could hardly happen, because of missing exceptions during the "worng" config class mappings (as stated in the question)
