[JBoss Seam] - Re: rendered problem for commandButton
by margielm
Hi,
I am facing the same problem, and I have no idea how I can resolve it.
Quick view on something like my application:
I have xhtml:
|
| <h:form>
| <h:commandButton action="#{myControler.addNewItem}" value="add" rendered="#{param.mode == 'create'}" />
| <h:commandButton action="#{myControler.updateItem}" value="update" rendered="#{param.mode == 'update'}" />
|
| </h:form>
|
and controler:
| @Stateful
| @Name("myControler")
| public class MyControlerBean implements MyControler {
| public void addNewItem(){
| logger.debug("entering adnewitem");
| //rest of the method body
| }
| public void updateItem(){
| logger.debug("entering updateitem");
| //rest of the method body
| }
| }
|
And when mode parameter value is create or update on generated site everything seems to be ok, one button is displayed another is not- so exactly what I wanted to get.
BUT!!! When I click button no action is invoke. I don't see any log on jboss console.
What is wondering - when I write true/false explicate to rendered attribute everything is ok. Prefered action is invoked.
I am using jboss seam 1.2.1GA, Jboss AS 4.2.1 and JSF 1.2
Please help :)

[JBoss Seam] - Base is null
by w17chm4n
I`m having a problem while trying to run my application (Seam 1.2.1) on JBoss 4.0.5.
Let the code explain...
controllertest.jsp (jsf)
| <%@page contentType="text/html"%>
| <%@page pageEncoding="UTF-8"%>
|
| <%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
| <%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
|
| <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
|
| <html>
| <body>
| <f:view>
| <h:form id="controller">
| <p>
| <h:commandButton value="Add new category (QuestionCategoryManger)" action="#{QuestionCategoryManager.test}"/>
| </p>
| </h:form>
| </f:view>
| </body>
| </html>
|
QuestionCategoryManager
| import java.util.List;
| import javax.ejb.Local;
|
| @Local
| public interface QuestionCategoryManager {
| String test();
| void addCategory(String categoryName);
| void removeCategory(long id, boolean withQuestions);
| void removeCategory(String categoryName, boolean withQuestions);
| QuestionCategory getQuestionCategoryById(long id);
| QuestionCategory getQuestionCategoryByName(String categoryName);
| List<QuestionCategory> getAllQuestionsCategories();
| }
|
QuestionCategoryControllerBean
| mport javax.ejb.Stateless;
| import javax.persistence.EntityManager;
| import javax.persistence.PersistenceContext;
|
|
| /**
| *
| * @author W17chM4n
| */
|
| @Stateless(name="QuestionCategoryManger")
| public class QuestionCategoryManagerBean implements QuestionCategoryManager {
|
| @PersistenceContext
| private EntityManager em;
|
| public String test() {
| return "success";
| }
|
| public void addCategory(String categoryName) {
| em.persist(new QuestionCategory(categoryName));
| }
|
| public void removeCategory(long id, boolean withQuestions) {
| }
|
| public void removeCategory(String categoryName, boolean withQuestions) {
| }
|
| public QuestionCategory getQuestionCategoryByName(String categoryName) {
| return (QuestionCategory)em.createQuery("from QuestionCategory q where q.categoryName='" + categoryName + "'").getSingleResult();
| }
|
| public QuestionCategory getQuestionCategoryById(long id) {
| return (QuestionCategory)em.createQuery("from QuestionCategory q where q.id="+String.valueOf(id)).getSingleResult();
| }
|
| public List<QuestionCategory> getAllQuestionsCategories() {
| return em.createQuery("from QuestionCategory q").getResultList();
| }
| }
|
So here it is. I`m building it with maven, and while deploying, everything is allright. But when i push the button i get this:

I don`t know why seam can`t find ejb bean. Is there a way to test if SeamInterceptor is running ?
JNDI Namespace tells that the bean exists:
| +- Inquisitor (class: org.jnp.interfaces.NamingContext)
| | +- QuestionCategoryManger (class: org.jnp.interfaces.NamingContext)
| | | +- local (proxy: $Proxy191 implements interface com.blstream.inquisitor.ejb3.interfaces.QuestionCategoryManager,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
|
Can anybody help me ?
