Hi, I've got a bunch of CMPs (running on JBoss 3.2.5) representing an order with orderLine. Here are the links:

Order -1----*-> OrderLine -1----1-> Item
|
V
Customer

My problem comes when I want to create an order. With existing Customer and Items, I want to create (in one go) an Order with its OrderLines. When I do that I've got the following exception

15:53:01,187 ERROR [LogInterceptor] TransactionRolledbackException in method: public abstract java.lang.String com.yaps.
petstore.server.service.order.OrderService.createOrder(java.lang.String,java.util.Map) throws javax.ejb.CreateException,

I've localised the problem but I can't solve it or explain it. It's in the postCreate of the OrderLine CMP when it calls the setOrder method. If I take it our, the exception doesn't occur but in the database I've got a foreign key set to null, normal.

public String ejbCreate(int quantity, double unitCost, OrderLocal order, ItemLocal item) throws CreateException, CheckException {

 setId(getUniqueId(COUNTER_NAME));
 setUnitCost(unitCost);
 setQuantity(quantity);
 return null;
 }

 public void ejbPostCreate(int quantity, double unitCost, OrderLocal order, ItemLocal item) throws CreateException, CheckException {

 setOrder(order);
 setItem(item);
 }

The method setOrder IS a CMR Method and it's declared abstract like all the other getters and setters

public abstract int getQuantity();
 public abstract void setQuantity(final int quantity);

 public abstract double getUnitCost();
 public abstract void setUnitCost(final double unitCost);

 public abstract OrderLocal getOrder();
 public abstract void setOrder(final OrderLocal order);

 public abstract ItemLocal getItem();
 public abstract void setItem(final ItemLocal item);

And here are bits of the ejb-jar.xml

<entity>
 <display-name>OrderEB</display-name>
 <ejb-name>OrderBean</ejb-name>
 <local-home>com.yaps.petstore.server.domain.order.OrderLocalHome</local-home>

 </cmp-field>
 <cmp-field>

 </cmp-field>
 <primkey-field>id</primkey-field>
 </entity>

And the relationship part

<ejb-relation>
 <ejb-relation-name>OrderBean - OrderLineBean</ejb-relation-name>
 <ejb-relationship-role>
 <ejb-relationship-role-name>order-has-orderLines</ejb-relationship-role-name>
 <multiplicity>One</multiplicity>
 <relationship-role-source>
 <ejb-name>OrderBean</ejb-name>
 </relationship-role-source>
 <cmr-field>
 <cmr-field-name>orderLines</cmr-field-name>
 <cmr-field-type>java.util.Collection</cmr-field-type>
 </cmr-field>
 </ejb-relationship-role>

 <ejb-relationship-role>
 <ejb-relationship-role-name>orderLine-belongs_to-order</ejb-relationship-role-name>
 <multiplicity>Many</multiplicity>
 <relationship-role-source>
 <ejb-name>OrderLineBean</ejb-name>
 </relationship-role-source>
 </ejb-relationship-role>
 </ejb-relation>

Does anybody have an idea, I've been looking everywhere and can't find any solution.

Thanks in advance

Antonio
