For me the problem appears without any reference/collection.
If you get a simple query to retrieve an object, modify an attribute of this object in
the database and get this object a second time the attribute won't be updated.
Is it a bug or is there something wrong in my app?

I think what you're describing is a different problem. If your changing
your database outside of OJB, then you probably don't want to use the

it is possible to change the persistent object metadata

Thx Jakob,
I've changed the IndirectionHandler class in the release 2 as you
recomended:
public Object invoke(Object proxy, Method method, Object[] args)
{
Object subject = null;
try
{
subject = getRealSubject();
// handle toString
I'm a relative newbie to OJB, but i'll give this one a whirl.

Hello everybody,
does anybody has a workaraound or temporary patch for

This bug was reported twice in scarab. It occurs when inserting or

Can you please elaborate on what you mean by in a per thread manner or
global? I thought OJB can only have a global metadata definition. Are you
implying by per thread to mean that each application can dynamically load
its own metadata using the same OJB instance? If that is the case, then it

Looking at the performance benchmarks at OJB's page, there's a dramatic

the object locking features with ODMG, or is it because ODMG uses PB and

It's beacuse ODMG is a full fledged Object transaction manager.
It does a full tracking of object states during transactions etc.
This causes all the overhead. The real persistence work is done with
the underlying PB API and is not slower than native PB operations.

Is it acceptable for OJB to cause a StackOverflow Exception (infinite
recursion)? I get this when I do refresh=true on bidirectional
references. The problem isn't there if you don't say refresh, but in that
case, OJB doesn't produce reliable/consistent data.
