Hi all,
I found something strange when using Query.setStartAtIndex(...) and
Query.setEndAtIndex(.).
The following is taken from a JUnit TestCase:
Query query = getAQuerySomeWhere();
query.setStartAtIndex(start);
query.setEndAtIndex(end);

Betreff: strange behaviour Query.setStartAtIndex() and
Query.setEndAtIndex()
Hi all,
I found something strange when using Query.setStartAtIndex
of order1 (not proxied) is not equal to the identity of
item.getOrder() because of different primitives used to build the pk.
there have been post about identities created based on the definition in
the repository and other based on the jdbc-types.

Hi all,
I just wrote the following mail to the user list. Here it is a second more
time for two reasons:
1) I used a mail account not subscribed to the list, hence I do not know
whether it will be accepted.
2) I just updated my App for use with OJB 1.0. The problem did not change.
So forget about

Is there an easy way to get this fixed?

it may interest you, especially those of you that are already using AXgen

I want to propose a patch for the proble described below.
As I tried to describe, the fact, that a object is newly created does not

Consequently I propose to replace the following code in

Hi Dirk,
I'm not sure whether I understood your problem. Maybe I can help anyway...
First, I'm not sure whether you really need to declare the extents for all
your classes. Wouldn't it be sufficient to simply have all model classes
having the same superclass BaseClass. If this is the case,

I've got the following problem: I implemented a PBLifecycleListener to do

you could try to define an extent in classdescriptor of Address pointing
