ADF BC : MA

Question

Hi,
I am new to ADF Business Components. I am into a project where i use only the ADF BC as ORM/DB Operations and for the front end I use some other framework. The Problem is.
I have two entity objects and a ViewLink between them. [Relation between "Order" to "Item" is (1 to many relation)].
[I saw many examples in forums where its explained with View Objects But here I DID NOT create any View Object. I have only Entity Objects]
(1) OrderEO [Entity Object for Order Table]
(2) ItemEO [Entity Object for Items Table]
(3) OrderItemsViewLink [A Viewlink where OrderEO.OrderId = ItemEO.OrderId]
All The Primary keys (for the "Order" and "Items" table ) are handled by Trigger+Sequence at the time of insert in DB side.
I created custom method to insert "Order" individually it worked fine.
I created custom method to insert the "Item" individually it worked fine.
But...
When I created and "Order" with some "Items" It failing to insert and throws an
Error : oracle.jbo.InvalidOwnerException: JBO-25030: Failed to find or invalidate owning entity: detail entity ItemEO, row key oracle.jbo.Key[0 ].
My Custom Method in the AppModuleImpl is like below :
public void createNewOrderWithNewItems() {
String entityName = "com.proj.entities.OrderEO";
EntityDefImpl orderDef = EntityDefImpl.findDefObject(entityName);
OrderEOImpl newOrder = (OrderEOImpl)orderDef .createInstance2(getDBTransaction(),null);
try {
// 3. Set attribute values
newOrder .setOrderStatusCode("CREATED");
RowIterator items = newOrder .getItemEO();
Row newDraftLineRow = draftLines.createAndInitRow(null);
items .insertRow(newDraftLineRow);
newItemRow .setAttribute("itemDate", new Date());
newItemRow .setAttribute("itemQty", new Number(10));
// 4. Commit the transaction
getDBTransaction().commit();
} catch (SQLException e) {
e.printStackTrace();
} catch (JboException ex) {
getDBTransaction().rollback();
throw ex;
Here the "Order" is also new and related Items is also new. What I expect is to save the Order with Items in one transaction. How to achieve this. Please suggest.
Thanks
Narayan
