I have a similar solution in my job. I've done in the following way:
class A {
...
}
class A_normal extends A {
}
class A_history extends A {
}
Only A_normal and A_history are mapped in repository.xml.
So, if I need to manipulate the object, I use class A. To store a normal object, I use
and
Is this already in CVS? This fix is correct?

After some research, I've found an implementation that works:

Collection coll;
if(getData()instanceof ManageableCollection) {
getData().clear(); // ECER: assure
Since yesterday (I've downloaded CVS HEAD sources and compiled), I can't get a

proxy=dynamic.
The stack trace is:

Hi all,
Nope I didn't found any thing on the subject, I found this behaviour while
debugging ojb (
thank to eclipse ). And then reading comment in example bundled with ojb.
Same behaviour with all ( I played with ) layer ( odmg, PB ).
It's should

Hi all,
I'm really lost with auto-delete feature...
The model:
0,n 0,n
Actors Roles
The RDBMS schema:
actors
.
Is this a expected behaviour, or is needed some kind of config I lost?
In meantime, I've created a trigger in database to do this job, so it isn't a real
problem,
but I think it's should be managed by OJB.
Thanks for any tips,
Edson Richter

For the slow people in the class, can you please explain this problem in
a little more detail? If I have to tweak cache timeouts to get correct
behavior on simple references, then there 's a bug hiding in here somewhere.
Thanks.

Interesting is that this code is right (will only occur if cds.getCascadeStore()
returns true):
private void storeCollectionObject(CollectionDescriptor cds, Object otherObject)
{
// if cascade store: store associated object
if (cds.getCascadeStore())

Hi Fabiano,
Try JDBC-TYPE='TIMESTAMP' - and try and use java.sql.Date instead of
java.util.Date... I
have run into problems before with java.util.Date but YMMV.
Good Luck,
Rob :)

If you are working with DefaultCacheImpl, take a look at config parameters.
Otherwise, are there any exceptions (stack trace), messages (they can be very usefull

Thanks for your quick answer, I cheched the OJB.properties file an I
was using DefaultCacheImpl I change it to ObjectCacheEmptyImpl and now
it is working as I was expecting.
Now just to learn the reasons
on OJB (the fact it not check if all extents are declared),
and I
really don't know even if it's already fixed on latest sources.
