Why my commandButton from JSF is not executing and returning an error ?

Question

I have a form submited with ajax which normally must execute the removeArticle function. The problem is when I'm clicking the button, the function is never called and a beautiful error message is returned (displayed with alert) telling me : "serverError: class javax.ejb.NoSuchEJBException CORBA OBJECT_NOT_EXIST 9998 Maybe; nested exception is: org.omg.CORBA.OBJECT_NOT_EXIST: vmcid: 0x2000 minor code: 1806 completed: Maybe". I'm using in another part a similar (almost) form for adding a cocktail. When I place my removeArticle calling into this other form it's executed ...

My code is the following :

HTML Elements IDs shouldn't have "-" like in your: <h:form id="cocktail-panier"> AND <div id="cart-component">, this causes Problems in js. replace all these ids with underscore cart_component, or use Java Style like cartComponent

use commandButton like this:

<h:commandButton
                title=""
                value="Supprimer les articles "
                type="button">
                <f:ajax execute="@form" render="@all" listener="#{dataManagedBean.removeArticle(item)}"/>
</h:commandButton>

Ajax-Listener method like:

public final void removeArticle(final YourItemClass item){

you use jstl components. JSTL will run on build time, and if your Bean is requestScoped, then the render / action of commandbutton will not fire.

change your bean (if not) to ViewScope or SessionScope, and use rendered instead of <c:if...

somthing like:

replace this <c:if test="#{dataManagedBean.cartLength > 0}">

width this:

<h:panelGroup display="block" rendered="#{dataManagedBean.cartLength > 0}">
.....

ADDITIONALY: you use templates. your template should somthing like this:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      >
<h:head>
    <meta charset="UTF-8" />
    <meta http-equiv="content-type" content="text/html; charset=UTF-8" />
    <h:outputStylesheet name="stylesheet.css"/>

    <title>${pageTitle}</title>

In your XHTML Page where you use this template, you don't need to declare XML or HTML docType, and use your template directly:

<ui:composition template="template/common/commonLayout.xhtml"
....

Use <h:head> in your template instead of the <head>, else JSF will not include the jsf.js in the document

The problem was the nested ui:repeat ! I replaced my 2 ui:repeat by 2 c:forEach and everything is working fine !
