[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-685) JSF postback doesn't include conversation identifier

JSF postback doesn't include conversation identifier ---------------------------------------------------- Key: JBSEAM-685 URL: http://jira.jboss.com/jira/browse/JBSEAM-685 Project: JBoss Seam Issue Type: Bug Components: Core, JSF Affects Versions: 1.1.1.GA Reporter: Christian Bauer Assigned To: Gavin King Fix For: 1.1.5.GA I'm at a point where I'm almost certain I have found a bug. It's difficult to reproduce and isolating it more would cost too much time. Take a seam-gen project and create a new entity, name it 'Foo'. Add a page called 'fooDisplay.xhtml' that shows a single Foo object: Name: <h:outputText value="#{currentFoo.name}"/> <s:link styleClass="button" value="Edit Foo" action="edit"/> Add the outcome to pages.xml: <page view-id="/fooDisplay.xhtml" action="#{fooDisplay.resolveFoo}"> <param name="fooId" value="#{fooDisplay.fooId}" converterId="javax.faces.Long"/> <navigation from-action="edit"> <render view-id="/foo.xhtml"/> </navigation> </page> So I can call this page now with /docDisplay.xhtml?fooId=123 and I will see the object. This is the job of the FooDisplay backing bean: @Name("fooDisplay") public class FooDisplay { private Long fooId; public Long getFooId() { return fooId; } public void setFooId(Long fooId) { this.fooId = fooId; } @In(create = true) private EntityManager entityManager; @Out(scope = ScopeType.EVENT, required = false) private Foo currentFoo; @Transactional public void resolveFoo() { entityManager.joinTransaction(); currentFoo = entityManager.find(Foo.class, getFooId()); } } The problem occurs when rendering the edit page, foo.xhtml. The processing after a click on Edit is as follows: - Restore View /fooDisplay.xhtml - Run FooDisplay.resolveFoo(), @Out(Event) currentFoo - Render Response /foo.xhtml, triggers FooHome.create(), @Begin I've made no changes to this seam-gen produced page, only adapted the Home manager to accept not a request parameter, but injection: @Name("fooHome") public class FooHome extends EntityHome<Foo> { @In @Out Foo currentFoo; @Override public Object getId() { if (currentFoo==null) { return super.getId(); } else { return currentFoo.getId(); } } @Override @Begin public void create() { super.create(); } } (I know that the injection/outjection here is not complete.) The issue: The long-running conversation identifier is not rendered into the Edit page, and a click on "Save" or "Update" breaks. The following request does not contain a conversation identifier. If I modify the Edit page and use s:button or s:link and not h:commandButton, the conversation identifier is rendered into the submit and everything works.
