Bug in NHibernate 2.0 Beta 1 relating to Custom Types - Resolved in Beta 2

Friday, 27 June 2008 13:10 by PhilJapikse

Started working with NHibernate last week, and while hooking up my POCO to
SQL Server TimeStamp field type, found a bug in the 2.0 (Beta 1) code base.

In the CustomType class constructor, the name field is getting set to the
userTypeClass.Name property (line 33).

This causes an exception to be thrown when NHibernate tries to use your
custom type since it can't get to it if not fully qualified.

The fix is simple:

change:
name = userTypeClass.Name;
to
name = userTypeClass.AssemblyQualifiedName;

Update (14-July-2008): This has been resolved in the 2.0 Beta 2
code base.

Happy Coding!

In your mapping files, do you have the version tag set correctly?

Use something like this:

<version name="RowVersion" column="LastModified"
type="Pinnacle.NHibernate.Utilities.UserTypeTimestamp,Pinnacle.NHibernate.Utilities"
generated="always" unsaved-value="null"/>

The element that is causing this error is a user defined type. And the exception that I see is:

I just updated everything to CR2 (see my post for compiling CR2 in VS2008 and the 3.5 FW), and it worked fine. All of my tests passed. What is the error that you are getting? (I will check my post on the custom class to make sure it's current, but won't get to that until tomorrow.)

Have you tried this out in the beta2 release? I still see this bug, even with the NHibernate 2.0 CR2 source.

Thanks.

Beta 2 codebase fixed this bug.

Ok, I didn't follow the correct process on my first bug report. I created a new bug with sample code and tests, etc. here http://jira.nhibernate.org/browse/NH-1377

I did, and the response was that it is a non-issue. I responded with the link to the sample code that I used to discover the issue (probably should have done that first).
