Hi Gautam,
Bruno is right, you have to do two steps on insert of objects with
bidirectional references. Say class A and B have a bidirectional 1:1
reference, then do e.g.
A a = new A();
B b = new B();
a.setB(b); // set one reference
broker.beginTx
broker.store(a,..);
b.setA(a); // set other
b
Hello,
I guess you have to do the 2 steps in the same way with PB API. Database
constraints needs the same sequence of insert/update.
If using PB API, i don't think you're dealing with rollback ability, if
not, write the 2 steps as it were 2 standalone PB processes and it should
work.

Hello,
Is there a way to do the same using Persistence Broker APIs ?
Thanks and Regards,
Gautam.

The circular references have to be build in 2 steps :
First, create instances and link one relation.
Flush (write SQL insert and update)
Second, link with the second relation (in back side).

Your example :
tx.begin();
d = new Drawer();
f = new Finish();
tx.lock(d);
tx.lock(f);
d.setFini
Hello,
I have a scenario in which there are two classes which reference each
other. Eg. class Drawer references Finish and Finish references Drawer.
When I attempt to persist Drawer instance, an exception is thrown
suggesting that we cannot add or update a child row: a foreign key
reference fails
