Michael,
> Is childList the same as salesOrderList?
Sorry, I am not sure what you mean by "the same".
If you are asking is the entity self-referential, then the answer is no. The parent is named "SalesOrder" and the child is "OrderItem". It is a simple "to-many" relationship (one sales-order to many order-items).
More info:
I did some more testing and found that the problem is associated with older SalesOrders stored in the production server and seems to be creating an Exception on
objectContext.deleteObjects(salesOrder.getOrderItemList())
However, when I create a SalesOrder with new data, I cannot duplicate the Exception condition. So perhaps the Exception is somehow associated with the older data.
Also, I wrote my own "deleteObjects" method (for debugging purposes) and it appears to work fine with the new SalesOrders or seemingly as well the ObjectContext version and generated the same Exception with the older data.
The complication with debugging this issue is that the data is on the production server and once I attempt a test (even though it claims that it failed) the data is actually deleted, so I can't duplicate the test once all the data is deleted.
Thanks,
Joe
