Name and version of the database you are using:
MSSQL 9.00.1399.06
The generated SQL (show_sql=true):
The last SQL in there is:
SELECT code0_.ID as ID0_, code0_.Versionnumber as Versionn5_0_, code0_.Identifier as Identifier0_, code0_.CodeString as CodeString0_, code0_.Timestamp as Timestamp0_, code0_.Username as Username0_, code0_.ClassificationID as Classifi3_0_, code0_.Definition as Definition0_, code0_.Revisionnumber as Revision6_0_ FROM Code code0_ WHERE code0_.ID=@p0
But in the log there is no mistake that I can find.
Debug level Hibernate log excerpt:
The log is 10 files big. I just paste the last few lines. I cannot find an error inside the log:

The problem I have is that I get the strange exception "identifier of an instance of IFCC.Model.src.persistent.CodeReferencesCode altered from 0X0 (IFCC.Model.src.persistent.CodeReferencesCodeCompositeID) to 0X0 (IFCC.Model.src.persistent.CodeReferencesCodeCompositeID)". How can alter 0X0 to 0X0 ? It's the same?!?
Can anyone give me a hint what I might be doing wrong?
Thank you very much
