Bruce,
Thanx for the test harness. I will try and see if I can reproduce the
problem. I got it to work by creating the child objects outside of the
jdoStore callback method.
db.create(a);
a.createChildren(db);
I did try and see where the problem was but it was so hard to track down.
It was very intermittent and only showed up for objects with lots of
children.
Steve
