Hi Peter, i tried
* org.hibernate.dialect.OracleDialect * org.hibernate.dialect.Oracle9Dialect but no effect. An extension to the previous description: If you try to add a property (e.g. "hidden") first nothing happens (reload). If you try to add the property again you get a: java.sql.BatchUpdateException: ORA-00001: Unique Constraint (JBOSSPORTAL_2_6.SYS_C0011591) Exception as the property is already written to the database table!
