Hibernate not updating a null column

Hi All,
I've a DB table which has several columns. Hibernate can't update a DB row when a nullable column is null and through code I try to set it to a legal non-null value. That said, if the nullable column has a legal vale, Hibernate successfully updates its value. I can see the Hibernate generated UPDATE SQL in the log. Furthermore, while updating a nullable column which is null, Spring's Hibernate template doesn't return from saveOrUpdate() method call. In the log there's no exception. Seems like the exception is gets lost. Did anyone face the same issue?

Here's how it looks in code.

Service Layer

DAO Layer

What's happening here?
When I try to debug the app, it's strange to note that the control disappears after the saveOrUpdate call. The control never returns from the save method. Also, in the log file I can't see any exception propagated.
