Hello

I use version 3.1 of hibernate with a base data DB2 version 7.x
To resolve a problems of "optimistic lock", I use the attribute timestamp on the mapping hibernate for my business objects:

< timestamp
name="timestamp"
column="DATLIG"
unsaved-value="null"
/>

the problem is that hibernate does not save this column ! when I create a bo and I save it, I find a null value in data base , whereas normally I expects to find the current date value for the timestamp.

Does somebody encountered the same problem as me ? it is a problem of configuration ? of compatibility with DB2 ?

Thank you in advance for your assistance

Regards

Y.G
