Yeah, I believe it's flushed after requests right? But that's also good
enough since validation should have stopped unwanted values from comming
in..
He could try to use the wicket Iolite archetype for this, should be
simple to see, and Im very sure that he will see that only validated
values are in his objects...

Are you positive that hibernate will write this data to the session?
The default flush mode of Spring's OpenSessionInViewFilter is "NEVER":
http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/orm/hibernate3/support/OpenSessionInViewFilter.html#setFlushMode(org.hibernate.FlushMode)
I would try a simple test. Create a form that edits a bean that you
retrieve from the database (you retrieve it using a DAO/Repository
with a transaction demarcation of readOnly/required). Try to edit the
object but have it fail validation (don't set a required field or
something). Then, check your db to see if the values are there.

Thanks for the immediate replies.
Seems that, when using that pattern, one really always has to be aware of
the fact that changes are made directly to persistent instances. Otherwise
it could easily happen to get inconsistent data into the DB.

I'd say either enable transactions only for write operations or put all
together in one transaction (i.e. don't let hibernate flush the session
before you did your backend checks) ...
This works if each request is a single transaction. If multiple transactions
are run in one request, this wouldn't help, I think.

map a form to a bean and apply the changes to the entity yourself or do
all validation via I(Form)Validators
The first solution sounds like using DTOs and one reason of using OSIV is to
not to have to use DTOs.
But I like the FormValidator solution. That should work in most cases.
