I incorporated an AJAX-based page into the PrimeFaces tab, but unfortunately, it is not functioning correctly

I've added different pages within prime faces tabs and used ID-based forms on each page. However, when I enable AJAX for each page it doesn't work properly within the tab.

Here is a snippet of my primary index.xhtml page:

index.xhtml

<?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">
<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:p="http://primefaces.org/ui"
  xmlns:f="http://java.sun.com/jsf/core"
  xmlns:c="http://java.sun.com/jsp/jstl/core"
  xmlns:ui="http://java.sun.com/jsf/facelets">
<ui:composition template="templet.xhtml">
    <ui:define name="top">
... (content truncated for brevity)
    </ui:define>
</ui:composition>

Below are some other pages:

institute/Create.xhtml

<?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">
<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:ui="http://java.sun.com/jsf/facelets"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:f="http://java.sun.com/jsf/core">

<ui:composition template="/template.xhtml">
    <ui:define name="title">
... (content truncated for brevity)
    </ui:define>
</ui:composition>

department/Create.xhtml

<?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">
<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:ui="http://java.sun.com/jsf/facelets"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:f="http://java.sun.com/jsf/core">

<ui:composition template="/template.xhtml">
    <ui:define name="title">
... (content truncated for brevity)
    </ui:define>
</ui:composition>

When running these pages individually, the AJAX can find the form ID. But when including them on the index.xhtml page within a tab by clicking on a menu item, an error message is displayed:

<f:ajax> contains an unknown id 'departmentsetupform' - cannot locate it in the context of the component j_idt266

If anyone has any insight or assistance on how to resolve this issue, it would be greatly appreciated.

Answer №1

When mentioning the departmentsetupform form within itself, switch to referencing @form. Also, instead of using formname:messagePanel, simply refer to messagePanel directly as shown below:

<f:ajax execute="@form" render="messagePanel"/>
