Ajax tree does not load page

Question

I tried to alternate pages using ui:include on click of ajax (PrimeFaces) treenodes. The first page that load by default loads properly with all the components active but when I click on the other treenode to display another page, the latter page loads abnormally like having the dialog box visible below and the page hands.

I feel if I can force the page to reload partially as default on nodeSelect

index.jsf (gets loaded on login)

<p:layoutUnit position="west" size="270" header="Menu" collapsible="false" resizable="true">
    <p:ajaxStatus style="width:16px;height:16px;">
        <f:facet name="start">
            <h:graphicImage value="../design/ajaxloading.gif"/>
        </f:facet>
        <f:facet name="complete">
            <h:outputText value=""/>
        </f:facet>
    </p:ajaxStatus>
    <h:form id="appsMainControl">
        <ui:include src="/ui/appServices.jsf"/>
    </h:form>
</p:layoutUnit>
<p:layoutUnit position="center">
    <h:form id="centerControl">                    
        <ui:include src="/ui/#{amb.appToGet}.jsf"/>                   
    </h:form>
</p:layoutUnit>

The treeview component with the listener action. On node selection I want the child page to load appropriately

<p:layoutUnit position="west" size="270" header="Menu" collapsible="false" resizable="true">
    <p:ajaxStatus style="width:16px;height:16px;">
        <f:facet name="start">
            <h:graphicImage value="../design/ajaxloading.gif"/>
        </f:facet>
        <f:facet name="complete">
            <h:outputText value=""/>
        </f:facet>
    </p:ajaxStatus>
    <h:form id="appsMainControl">
        <ui:include src="/ui/appServices.jsf"/>
    </h:form>
</p:layoutUnit>
<p:layoutUnit position="center">
    <h:form id="centerControl">                    
        <ui:include src="/ui/#{amb.appToGet}.jsf"/>                   
    </h:form>
</p:layoutUnit>

The backing bean:

public void onNodeSelect(NodeSelectEvent event) throws Exception {
    ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();

    try {
        appToGet = appsMainDAO.appToGet(event.getTreeNode().toString());
        // ec.redirect("index.jsf");
        // System.out.println("Got "+appToGet);
        // appSubList = appsMainDAO.appsSubServicesList(appToGet, "Forms");
    } catch (Exception ex) {
        ex.printStackTrace();
        Logger.getLogger(appsMainBean.class.getName()).log(Level.SEVERE, null, ex);
    } finally {

    }

}

Don't do that. You are rubbing JSF the wrong way and thus heading into a major catastrophe.

It's impossible to explain the whole life cycle here, but - until you really know your way around JSF - just assume that facelet pages are _not_supposed_ to work like HTML pages.

Instead, they should work like window applications, where you have a certain number of widgets that don't really appear or disappear - they can be put in tabs, they can become disabled, but they stay where they were from the beginning.

If there is a finite number of things to include, the easiest option is to include them all and add some rendered="#{gui.current=='component1'}", so only one of the components is visible.
