Bug in @Datamodel ?!?
dexjam Dec 29, 2007 6:45 PMMaybe here some one can answer this.
I am running on
- JbossAS 4.2.2
- Seam 2.0.0.GA
Either it's abug in @Datamodel, or it's stupid me ...
Why is this working
--- BEGIN DOES work (TM) --- @Stateful @Name("admin") public class AdminUserBean implements Serializable, AdminUser { @PersistenceContext() private EntityManager entityManager; // @DataModel() // private List<User> userList; @Logger Log log; /*@Factory("userList") public void fetchUserList() { userList = entityManager.createNamedQuery("User.findAll").getResultList(); }*/ @Factory("userList") public List<User> getUserList() { return entityManager.createNamedQuery("User.findAll").getResultList(); } @Remove public void destroy() { //No special treatment } } --- END DOES work (TM) ---
And this isn't?
--- BEGIN DOESn't work (TM) --- @Stateful @Name("admin") public class AdminUserBean implements Serializable, AdminUser { @PersistenceContext() private EntityManager entityManager; @DataModel() private List<User> userList; @Logger Log log; @Factory("userList") public void fetchUserList() { userList = entityManager.createNamedQuery("User.findAll").getResultList(); } /* @Factory("userList") public List<User> getUserList() { return entityManager.createNamedQuery("User.findAll").getResultList(); } */ @Remove public void destroy() { //No special treatment } } --- END DOESn't work (TM) ---
The facelets page for this code is pretty straight forward:
<?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:s="http://jboss.com/products/seam/taglib" xmlns:rich="http://richfaces.org/rich" xmlns:f="http://java.sun.com/jsf/core" template="../templates/myTemplate.xhtml"> <ui:define name="content"> <h:messages/> <h2>User list size: #{userList.size()}</h2> <h:dataTable value="#{userList}" var="singleUser"> <h:column> <h:outputText value="#{singleUser.id}"/> </h:column> </h:dataTable> </ui:define> </ui:composition>
Somebody, please enlighten me how i can make the @Datamodel example work correctly or what is actually happening, that prevents it from working.
