Hmm, fun one. I suspect you may have run into the weird edge case.
I don't have an immediate answer on this -- need to play and dig.
Anyone else hit this before? Any chance you can create a unit test that
demonstrates the behavior? If so send it to me and I'll check it in and
dig in (or start p
If anyone is interested, my current solution for one case is:
1. add an Integer field listIndex to the item object
2. make the item object PersistenceBrokerAware, and in the
beforeUpdate() method
// update the position of this entry in the list
if (this.parent != null) {
Hi,
One problem solved - one to go.
GO is a group. A group has a collection of members (which is a
superclass of group), and has a collection of all groups that contain
it, and has a reference to RO.

exactly. Due to copy & paste I assigned a wrong column to the attribute

Is it safe for other parts of my code to use a PersistenceBroker like
this...

finally {
It sounds like there is actually a problem in the mapping from class ->
table where the activityId is listed.
Any chance you could post the full mapping for these classes, along
with the database schema?

Can anyone reply to my message? In question 1 I have wrongly

From looking at your configs I will venture that you are using the PB

As I understand it OQL queries always hit the database but the objects
can be resolved from the cache though. If you use the PB API for
accessing objects (you can do this from ODMG) then the cache is accessed
much more.
Good Luck,
