I integrated NH-466 into 1.2GA but still get an error with <join> ('invalid child element'). I included the steps I used for this. Does anyone know the code that I would need to check to see if I have the correct version? Did I perform the steps correctly -- is there any place where I need to include an XSD?

Background: I need to combine table-per-class-hierarchy and table-per-subclass; therefore, I was told that using a <join> in the <subclass> would work (I need to test if both the Get and the Save works properly for this).

DETAILED STEPS FOR INTEGRATING NH-466 to 1.2GA:
1. Create folder, C:\nHibernate
2. Right-click on C:\nHibernate; select 'SVN Checkout' w/ the following settings:
* 'URL of repository': htps://nhibernate.svn.sourceforge.net/s ... nhibernate
* keep 'HEAD revision' selected
3. Right-click C:\nHibernate, select TortoiseSVN - Merge; When Merge window pops up, make sure the following are set:
* URL" https://nhibernate.svn.sourceforge.net/ ... nhibernate
* Revision is selected
4. Separately merge each of the following: 2774, 2836, 2953, 2955
5. Open a command window; cd C:\nHibernate; NAnt set-net-2.0-framework-configuration visual-studio
6. From Visual Studio, open C:\RemoteNHibernate\src\NHibernate\NHibernate-2.0.csproj and build it
7. Copied the following from C:\Projects\nHibernate\src\NHibernate\bin\Debug-2.0

Hibernate version: It's a locally built version of 1.2.0.GA merged with the NH-466 patch; see detailed steps that I used for getting 1.2.0GA, merging the 4 SVN revisions for NH-466, building

Thanks,

I'm interested in using the <join> element too. Will that be available in a 1.2.1 release any time soon?

FYI - Karl Chu kindly sent me a built version of nHibernate w/ patch NH-466 (<join> tag) implemented. Unfortunately, something in my environment was problematic; I instead manually merged the NH-466 patch into the 1.2 GA -- here's the detailed cookbook http://forum.hibernate.org/viewtopic.ph ... highlight=

But, of course, something is not working :(. I checked NHibernate.nhibernate-mapping.xsd and the "subclass" element doesn't have the "join" in it. I also need to know where the .xsd file should be located.

Any chance I can get ahold of that build from Karl and give it a spin?

I created a separate email account for this; email me and I can send it to you.

Hi Bill, it is possible that you have not merged the patch correctly. Make sure you are merging the differences from the *trunk*. To check, open up the nhibernate-mapping.xsd file from your source and search for the following line:
You should find it on line 501. Within it, you should see this:
If not, you may not have merged correctly.

Hi Bill, I realized what I sent you the first time was a combined patch/diff file of the source, not the compiled DLL. If you want the compiled DLL, please send me another email.

khubla, you can also send me an email if you would like the pre-compiled DLL.

NOTE: We just confirmed a bug in the <join> patch. See NH-1059 on JIRA.

I must not have done the merge properly. I used TortoiseSVN for the Subversion client; there seems to be a potential for misuse in its merge user interface (http://www.svnforum.org/2017/viewtopic. ... 434f037da0). I annotated the cookbook steps to include the warning that the merge info may be incorrect.
