Hello all:
I have just finished upgrading to Hibernate 3.0 successfully, however; whenI run my application the primary key is set for the field "comment" of type "text" (which is defined as Clob in query). If I run the application using hibernate 2.1.8, the field is reterieved properly and is displayed corrently but with Hibernate 3.0 the field is set to primary key !!!



Hibernate version:3.0

Name and version of the database you are using: DB2 8.2

I was wondering if anyone really knows why this is happening, If I save a large text using Hibernate 3.0 in the Clob filed, the value is stored properly ( I have checked the database), but for the retrival, the value is set to the value of the primary key. However; the same code works fine with Hibernate 2.1.8, the actual text is retrieved.
