Child Records getting inserted before Parent

Question

HI All,
I have an Entity object (Vendors) that has a defined relationship to payments (12 months) when I create a new vendor record I'm creating the 12 child records that all works fine but when I try to issue a commit the child records get inserted first creating a constraint error. If I turn the constraint off and using the "Jbo.debugoutput=console" I can see the 12 months being inserted followed by the vendor record. The payment records vendor_id is being set to the correct parent but the insert is happing in the wrong order does anybody know how to control the order of the insert. There's a Association set between the Vendor entity and the payment entity. If I move the code to a view object it seems to work fine. But in this case we have multiply view objects on these entity objects and I'm trying to prevent having to write the same code in every view Object.
Here's the code for the Create on the Vendors EntityImpl
protected void create(AttributeList attributeList) {
super.create(attributeList);
// Set the default values and the Seq number for this new record
SequenceImpl seqNoImpl = new SequenceImpl("VENDORS_SEQ",getDBTransaction());
this.setVendorId( seqNoImpl.getSequenceNumber());
Number zeroAmt = new Number(0);
RowIterator paymentsIter = this.getVendorPayments();
// When creating a new Vendor create the 12 months of payment records
for (int i = 1; i < 13; i++) {
Row newRow = paymentsIter.createRow();
newRow.setAttribute("Month",i);
newRow.setAttribute("Amount",zeroAmt);
paymentsIter.insertRow(newRow);
Dose anybody have any ideas....

Pieter,
Thanks for the information!!
Using it I was able to get the process working. There where some interesting side affects. If I just turned on the "Composition Association" then no payment records got inserted into the database even though they where in the entity and view objects. I took the second recommendation of adding code to the PostChanges event and was able to get the parent and children inserted in the correct order.
Thanks again for the idea and information
