Hi,

13:04:28,000 ERROR XMLHelper:59 - Error parsing XML: XML InputStream(53) Attribute "optimistic-lock" is not declared for element "set".


Hibernate 3.0

</set>

.........

If I refer to the documentation =>
(12) optimistic-lock (optional - defaults to true): Species that changes to the state of the collection results in
increment of the owning entity's version. (For one to many associations, it is often reasonable to disable
this setting.)

Did I need to use other kind of Collection ?

Thanks,

Sorry for noise,
the problem was after migrating from 2. We need to change the header of each mapping document
