I have a problem with my Mojarra 2.1.6 web-application, I’m developing it using @ViewScoped

  • 0

I have a problem with my Mojarra 2.1.6 web-application, I’m developing it using @ViewScoped managed beans and each bean is attached to an xhtml page. This page is receiving some view params and after initializing the bean in that way:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:p="http://primefaces.org/ui"
template="/templates/general_template.xhtml">

<ui:define name="metadata">
    <f:metadata>
        <f:viewParam id="user" name="user"
            value="#{navegableUserData._ParamUser}" />

        <f:viewParam id="NavIndex" name="NavIndex"
            value="#{navegableUserData._QueueIndex}" />
        <f:event type="preRenderView"
            listener="#{navegableUserData.initialize}" />
    </f:metadata>
    <h:message for="user" />
</ui:define>

<ui:define name="general_content">
    <p:outputPanel autoUpdate="false" id="Datos_Loged" name="Datos_Loged"
        layout="block">
        <h:form id="SystemUserForm">
            <ui:include
                src="/system/manage_user/content/edit_user/system_user_data/system_user.xhtml">
                <ui:param name="manager" value="#{navegableUserData}" />
            </ui:include>
        </h:form>
    </p:outputPanel>
</ui:define>

As you can see, I have my pages nested into a general template which looks like that:

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html 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:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:p="http://primefaces.org/ui" xmlns:o="http://omnifaces.org/ui">

    <h:outputScript library="js" name="prime_translations.js" />
</h:head>

<h:body>
    <ui:insert name="metadata" />
    <o:importConstants
        type="com.company.system.view.beans.NavigationResults" />

<!-- More stuff -->

Problem comes when I make an ajax request such as a Primefaces table filtering. Although my backing bean is not being created again, <f:event type="preRenderView" listener="#{navegableUserData.initialize}" /> is being called again.

I’m doing a data loading based into view params and need that method to execute only when the page is rendered first time. I have been very careful using <c:xxx> tags and think that’s not the problem because I used them only in general template and my view beans properties are not attached to them. Also I have this problem with all my pages, so I think it is not an issue of an specific backing bean.

    If this occur only during ajax request, try the following:

    public void initialize() {
    if (!FacesContext.getCurrentInstance().isPostback()) {
        // -----------
        // -----------
    }
}
