Hi Gavin, can U answer for my questions abous Seam IceFaces? First. I have Seam app and sometimes when I clicking on action links got error "User session expired", but session not expireds. First I thougth this is my code problem but I made simple app, like this. | Main Page | <s:link value="ONE" action="#{homeAction.testOne}"/> | <s:link value="TWO" action="#{homeAction.testTwo}"/> | <br/> | <ice:form> | <ice:panelGrid styleClass="contentLayoutGridStyle" columns="1" border="0"> | <ice:panelTabSet tabPlacement="top" styleClass="componentPanelTabSetLayout"> | <ice:panelTab label="Panel A">AAA</ice:panelTab> | <ice:panelTab label="Panel B">BBB</ice:panelTab> | <ice:panelTab label="Panel C">CCC</ice:panelTab> | <ice:panelTab label="Panel D">DDD</ice:panelTab> | </ice:panelTabSet> | </ice:panelGrid> | </ice:form> | and stateful bean, | @Stateful | @Name("homeAction") | @Scope(ScopeType.SESSION) | public class HomeAction implements HomeConsole { | public HomeAction() {} | | @PersistenceContext | private EntityManager em; | | @SuppressWarnings("unchecked") | public String testOne() { | System.out.println("TestONE"); | try { | Query questionsListQuery = em.createQuery("FROM Category c"); | List<Category> questionsListSize = questionsListQuery.getResultList(); | System.out.println("Query Size:" + questionsListSize.size()); | } | catch(EJBException e) { e.printStackTrace(); } | return "/home.xhtml"; | } | public String testTwo() { | System.out.println("TestTWO"); | return "/home.xhtml"; | } | @Destroy @Remove | public void destroy() { System.out.println("homeAction - destroy"); } | } | when I clicking link like testOne,testTwo,...etc. sometimes maybe after 5-15 click-times and GO TO SWITCH TAB this error is thrown again! this is happen to when have those links and ice:dataTable connected to dataPaginator and try to switch page in paginator. Question is why? There's no source error. (I think) TEST II When I removed try {} block from testOne() and leaved ony system.out... (thought "user eror.." is thrown, by db) problem is not resoled. Test III I added those source code to your's booking-example (seam-icefaces app), to main page, error is still thrown. Can U tell me what I do wrong, and how to resolve it? In some post here on forum U said that seam/Icefaces apps need SeamVariableResolver to work clear. Can U tel me why, and why those SeamVariableResolver isnt' in Seam-Booking faces-config.xml? Regards! P.S. Can anyone check those simple example by clicking few times link and switch tab, or maybe this is only my problem.
