Probably duplicate of (http://issues.apache.org/jira/browse/TUSCANY-1661). Waiting for JunJei to retest against Trunk.

> Seemly ServiceReference.getConversationID() works incorrect. It always return null. see below code(I tried it on release 0.99):
> 1. @Test
> 2. public void testServiceRef(){
> 3. ServiceReference<CartService> cartRef = hex.getServiceReference(CartService.class,
> 4. "CartComponent/CartService");
> 5. assertNull(cartRef.getConversation().getConversationID());
> 6. assertNull(cartRef.getConversationID());
> 7. CartService cart = cartRef.getService();
> 8. assertNull(cartRef.getConversation().getConversationID());
> 9. assertNull(cartRef.getConversationID());
> 10. cart.updateItem("Avis", 1);
> 11. assertNotNull(cartRef.getConversation());
> 12. assertNotNull(cartRef.getConversationID()); // conversationID should not be null.
> 13. }
> From Line 1 - 11, all things work correctly. But LI 12 fails. cartRef.getConversationID() should return a non-null value since the conversation has been started.
> The component:
> <component name="CartComponent">
> <implementation.java class="samples.hex.cart.impl.CartImpl"/>
> </component>
> The Interface:
> package samples.hex.cart.services;
> import java.util.Map;
> import org.osoa.sca.annotations.Conversational;
> import org.osoa.sca.annotations.EndsConversation;
> @Conversational
> public interface CartService{
> public void updateItem(String itemID, int quantity);
> @EndsConversation
> public void empty();
> public Map<String, Integer> getItems();
> }
> The Implementation:
> package samples.hex.cart.impl;
> import java.util.HashMap;
> import java.util.Map;
> import org.osoa.sca.annotations.ConversationAttributes;
> import org.osoa.sca.annotations.ConversationID;
> import org.osoa.sca.annotations.Destroy;
> import org.osoa.sca.annotations.Init;
> import org.osoa.sca.annotations.Scope;
> import org.osoa.sca.annotations.Service;
> import samples.hex.cart.services.CartService;
> @Scope("CONVERSATION")
> @Service(CartService.class)
> @ConversationAttributes(maxIdleTime="1 seconds",
> maxAge="2 seconds",
> singlePrincipal=false)
> public class CartImpl implements CartService {
>
> @ConversationID
> protected String conversationID;
> private Map<String, Integer> cart;
> @Init
> protected void init(){
> if(cart==null)
> cart = new HashMap<String, Integer>();
> }
>
> public void empty() {
> System.out.println("[empty] "+conversationID + ":" + this);
> }
> public Map<String, Integer> getItems() {
> return cart;
> }
> public void updateItem(String itemID, int quantity) {
> if(quantity<=0)
> cart.remove(itemID);
> cart.put(itemID, quantity);
> System.out.println(conversationID + ":" + this);
> }
> @Destroy
> protected void destroy(){
> empty();
> }
> }
