I'm working on some code where I am trying to do the following: 1. User clicks a link to an action method on a SFSB 2. method is annotated with @Begin, using a custom conversation id 2a. the custom conversation id comes from the following 2a-1. a @Factory method in a SLSB creates a new persistent entity; the id of this entity will be appended to a String to create a custom conversation id 2a-2. the @Factory class would like to use the existing persistent entity if possible (avoid creating new persistent or querying for existing persistent entity) - thus, I have an @In for the entity. 2a-3. here is the class with the @Factory method:
| @Stateless | @Name("draftAccessRequestFinder") | public class DraftAccessRequestFinderBean implements DraftAccessRequestFinder { | | @Logger | private Log log; | | @PersistenceContext(unitName = "accessControlDatabase") | private EntityManager em; | | @In | private Principal userPrincipal; | | @In("#{conversation.id}") | private String conversationId; | | @In(required = false) @Out(scope= ScopeType.CONVERSATION) | private DraftAccessRequestMaster draftAccessRequestMaster; | | @Factory("draftAccessRequestMaster") | public DraftAccessRequestMaster createMaster() { | log.info("DraftAccessRequestFinderBean.createMaster() : conversationId -> "+conversationId); | log.info("DraftAccessRequestFinderBean.createMaster() : draftAccessRequestMaster -> "+draftAccessRequestMaster); | // create or load draftAccessRequest.... | if (conversationId != null && conversationId.indexOf(':')>0 && draftAccessRequestMaster == null) { | long id = Long.valueOf(conversationId.substring(conversationId.indexOf(':')+1)); | draftAccessRequestMaster = em.find( | DraftAccessRequestMaster.class, id | ); | log.info("loaded draftAccessRequestMaster -> "+draftAccessRequestMaster); | } | | if (draftAccessRequestMaster == null) { | if (userPrincipal == null) { | throw new RuntimeException("userPrincipal is null."); | } | if (!(userPrincipal instanceof UserPrincipal)) { | throw new RuntimeException("userPrincipal is not an instance of com.evergreen.jaas.UserPrincipal."); | } | draftAccessRequestMaster = new DraftAccessRequestMaster(); | draftAccessRequestMaster.setUserId( | ((UserPrincipal) userPrincipal).getUserid() | ); | draftAccessRequestMaster.setUserName( | ((UserPrincipal) userPrincipal).getPersonName() | ); | em.persist(draftAccessRequestMaster); | em.flush(); // we need to obtain a PK for this entity now... | } | return draftAccessRequestMaster; | } | } | 3. here is the SFSB that wants the custom conversation id as well as a reference to the persistent entity: | @Stateful | // Seam - defaults to Conversational context... | @Name("accessRequestManager2") | public class AccessRequestManager2Bean implements AccessRequestManager2 { | | @Logger | private Log log; | | @PersistenceContext(unitName = "accessControlDatabase") | private EntityManager em; | | @In | private UserPrincipal userPrincipal; | | // for development purposes only - todo remove this | @In | private Conversation conversation; | | @In(create=true) @Out(scope= ScopeType.CONVERSATION) | private DraftAccessRequestMaster draftAccessRequestMaster; | | @Out | private List<String> errors = new ArrayList<String>(); | | | /** | * Start a new add-access request. This method also generates the conversationId to | * use in the conversation that beans of this class are associated with. | * | * This is complicated - in 1 swoop, we need to | * 1 - create the DraftAccessRequestMaster for the conversation component | * 2 - | */ | @Begin(id = "DraftAccessRequestID:#{draftAccessRequestMaster.id}", join = true) | public void startAddRequest() { | log.info("startAddRequest()"); | log.info(conversation); | log.info("conversation.id = " + conversation.getId()); | log.info("conversation.parentId = " + conversation.getParentId()); | | if (draftAccessRequestMaster == null) { | log.info("draftAccessRequestMaster is null...not expected."); | } | .... | } | } | 4. here is a link that calls the SFSB method: | <s:link action="#{accessRequestManager2.startAddRequest}" value="Add 2" | title="Add entitlements to an application for a user."> | </s:link> | 5. and here is a log of what occurs | First click of link... | | 10:53:32,805 INFO com.evergreen.accesscontrol.impl.DraftAccessRequestFinderBean - DraftAccessRequestFinderBean.createMaster() : conversationId -> 3 | 10:53:32,805 INFO com.evergreen.accesscontrol.impl.DraftAccessRequestFinderBean - DraftAccessRequestFinderBean.createMaster() : draftAccessRequestMaster -> null | 10:53:32,805 INFO com.evergreen.accesscontrol.entity.DraftAccessRequestMaster - new DraftAccessRequestMaster() | 10:53:32,821 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean - startAddRequest() | 10:53:32,821 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean - [EMAIL PROTECTED] | 10:53:32,821 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean - conversation.id = DraftAccessRequestID:50 | 10:53:32,821 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean - conversation.parentId = null | | Second click of link (expecting to find draftAccessRequestMaster in memory for conversation but it's not found...) | | 10:53:36,915 INFO com.evergreen.accesscontrol.impl.DraftAccessRequestFinderBean - DraftAccessRequestFinderBean.createMaster() : conversationId -> DraftAccessRequestID:50 | 10:53:36,915 INFO com.evergreen.accesscontrol.impl.DraftAccessRequestFinderBean - DraftAccessRequestFinderBean.createMaster() : draftAccessRequestMaster -> null | 10:53:36,930 INFO com.evergreen.accesscontrol.entity.DraftAccessRequestMaster - new DraftAccessRequestMaster() | 10:53:36,930 INFO com.evergreen.accesscontrol.impl.DraftAccessRequestFinderBean - loaded draftAccessRequestMaster -> DraftAccessRequestMaster{...} | 10:53:36,930 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean - startAddRequest() | 10:53:36,930 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean - [EMAIL PROTECTED] | 10:53:36,946 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean - conversation.id = DraftAccessRequestID:50 | 10:53:36,946 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean - conversation.parentId = null | So note that I @Out(ject) the entity to Conversation scope, however, when the link is clicked the second time the SLSB and the SFSB don't have an instance of draftAccessRequestMaster injected. So why can't I find my conversational-scoped entity? It looks like the conversation is correctly @Begin(ning) or joining based on whether or not the conversation exists.
