EJB-QL CMR traversal returns wrong interface type
-------------------------------------------------
Key: JBAS-1296
URL: http://jira.jboss.com/jira/browse/JBAS-1296
Project: JBoss Application Server
Type: Bug
Components: CMP service, EJBs
Versions: JBossAS-4.0.1 Final, JBossAS-4.0.0 Final
Environment: Windows XP with JBoss 4.0.0 and JBoss 4.0.1
Xdoclet, Eclipse 3.1
Reporter: Wilson Pu

Priority: Critical
// Same bug posted on SourceForge with attachment
Hello,
JBOSS App. Srv. returns/contains wrong interface type with CMR traversal using
EJB-QL. We recreated the line item example from Mastering EJB Appendix D on
EJB-QL entity bean relationship traversal (page 574).
Test case below.
We created 3 tables:
Customer
---------
customerId (pk)
name
Order
---------
orderId (pk)
customerId (fk)
date
LineItem
---------
lineItemId (pk)
orderId (fk)
sku
quantity
On the CustomerBean, we defined a finder method using Xdoclet.
@ejb.finder
signature="Collection
findCustomerLineItems(int customerId)"
unchcked="true"
query="SELECT OBJECT(l) FROM Customer AS c,
IN(c.orders) o, IN (o.lineItems) l WHERE c.customerId=?1"
result-type-mapping="Local"
We also defined CMR for getting the orders from the customer bean and getting
the lineitems from the order bean.
Base on the finder method, we are expecting to return a collection of
LineItemLocal interface. However, we got CustomerLocal interface instead.
