Updates work but saves throw an exception...


How do you get it to save before the update anyway? Or you may need to tell more details about this scenario...

I fixed this issue but it looks like a hack to me.. I used native SQL query to insert.



Hey Vijitha, To test the update I manually inserted the values into the database and then did an update. It worked, so basically sessionFactory.getCurrentSession().update works but sessionFactory.getCurrentSession().save throws a class cast exception.

I think it has something to do with the primary key. It fails for all the tables where I don't have a sequence number generator and I manually enter the primary key.
