Website Admin: Update Entity - Item has already been added. Key in dictonary

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Starting with a default CodeSmith build of a small db. E.g. with
Articles and Categories tables.
2. Running the Website: Admin/Articles.aspx -> Select an article to edit.
3. Make a change to a field, then click "Update".

What is the expected output? What do you see instead?
This error occurs sporadically - it is not congruent. We expect it save
changes and show the edit page. Occationally we get a "Item has already
been added. Key in dictionary: 'ArticlesLib.Entities.Articles'...

What version of .netTiers and CodeSmith are you using?
.netTiers v2.3.0.812
CodeSmith 5.1.6 Revision 9466

Forgot to mention, this doesn't seem to happen if I enable Atlas in the website
configuration area of the .netTiers template.

Cheers.
