The example demonstrates blocking of <h:form> by <pe:blockUI>.
<h:form id="form" prependId="true">
<pe:blockUI target="form" widgetVar="blockBodyUIWidget">
<h:panelGrid columns="2">
<h:graphicImage library="default" name="images/ajax-loader1.gif" class="block-ui-image"/>
<h:outputText value="#{messages['blockui.panel.message']}" class="block-ui-text"/>
</h:panelGrid>
</pe:blockUI>
<p:commandButton id="btnSubmit"
onstart="PF('blockBodyUIWidget').block()"
oncomplete="PF('blockBodyUIWidget').unblock();}"
update=":form:dataGrid" actionListener="#{bean.listener}"
icon="ui-icon-check"
value="Save">
</h:form>
This blocks <h:form> but there is a template with a header and a left side bar which are not blocked by doing so.
I have tried to block <h:body id="body"> <pe:blockUI target="body"... on the template page but that didn't work ending with an exception indicating, "Cannot find component with the id body in the view."
So, how to target the entire page?
Although I'm using <pe:blockUI> of PrimeFaces extension, the same thing can be demonstrated by <p:blockUI> of PrimeFaces
Give an id to your body and then reference it on the block argument of the <p:blockUI> component.
Example:
<h:body id="entirePage"/>
and
<p:blockUI id="blockUI" widgetVar="blockBodyUIWidget" block=":entirePage"/>

My page contains a login header that i include via ui:include. The included page contains a dialog with a p:commandButton. When the user logs in, the include page is refreshed properly according to the #form in the update attribute. I also want to update a component outside the included page, that shall display a button when the user is logged in. The include page refreshes and the name of the logged in user is displayed. But the button in the main page is not shown. It is displayed if I refresh the page though. I can't figure out what I'm doing wrong here. Anyone have any ideas.
The header page also displays the commandLink component properly. But when clicking the logout link, the button in the main page is not removed. Since the commandLink does not use ajax, I assume that a normal page POST is done. Which should reload the whole page. Doesn't this work from a page that have been referenced with ui:include?
The login page is using a session scoped backing bean. The main page is view scoped.
Here's the included xhtml (login.xhtml):

This one is included in the following main page:
...
<ui:include src="login.xhtml" />
<h:form id="createform">
<h:panelGroup id="createbutton" layout="block">
<p:commandButton id="createnew"
ajax="false"
action="#{recepieController.createNewRecipes}"
value="Create new recipe"
rendered="#{recepieController.loggedIn and !recepieController.create and !recepieController.viewOnly and !recepieController.edit}"
accesskey="s">
</p:commandButton>
</h:panelGroup>
</h:form>
You cannot rerender a non-rendered component. If you partially render a button, and the button is not rendered, you cannot call an update on that button, because it does not exist in the DOM.
You have to call the AJAX update on the parent naming container, that is ALWAYS rendered. Thus, update the :createform rather than the button inside. The form is always rendered, no matter what.
I found the issue. In my commandButton "createnew", I used the wrong value to render on.
<p:commandButton id="createnew"
ajax="false"
action="#{recepieController.createNewRecipes}"
value="Create new recipe"
rendered="#{recepieController.loggedIn and !recepieController.create and !recepieController.viewOnly and !recepieController.edit}"
accesskey="s">
</p:commandButton>
It should use my session scoped bean (loginController) to check if the user is logged in. Changing to the following works.
<h:panelGroup id="createbutton">
<p:commandButton id="createnew"
ajax="false"
action="#{recepieController.createNewRecipes}"
value="Create new recipe"
rendered="#{loginController.loggedIn and !recepieController.create and !recepieController.viewOnly and !recepieController.edit}"
accesskey="s">
</p:commandButton>
</h:panelGroup>
Note the difference rendered="#{loginController.login ...} instead of rendered="#{recepieController.loggedIn}"
The recepieController also has a loggedIn attribute which I set, but since the page is not re-posted I guess the value is not changed for the attribute when I login.
However, I believe I tested to use ajax="false" in the p:commandButton for the login dialog which I guess should reset the view scoped version of my loggedIn attribute. I don't fully understand why that didn't work.
I have the maven dependency for omnifaces for version 1.11 (as my target is JDK 1.6). Richfaces 4.5.6 final, myfaces 2.2.8. And, against a viewscoped bean I have got this xhtml:
<ui:define name="content">
<f:loadBundle basename="au.com.erb.facility.ui.facility"
var="property" />
<o:highlight styleClass="error" />
<h:panelGrid columns="2">
<rich:validator event="change">
<o:outputLabel value="#{property.absClientNumber}" for="input1" />
<h:inputText id="input1"
value="#{facilityBean.facilityForEdit.alternateKey.absClientNumber}"
label="ABS Client Number" />
<o:outputLabel value="#{property.facilityid}" />
<h:inputText
value="#{facilityBean.facilityForEdit.alternateKey.facilityId}"
label="Facility Id" />
<h:outputLabel value="#{property.rfsAccountGroup}" />
<h:inputText value="#{facilityBean.facilityForEdit.rfsAccountGroup}"
label="RFS Account Group" />
<h:outputLabel value="#{property.rfsAcctCustomerNumber}" />
<h:inputText
value="#{facilityBean.facilityForEdit.rfsAcctCustomerNumber}"
label="RFS Account Customer Number" />
<h:outputLabel value="#{property.rfsAcctLedger}" />
<h:inputText value="#{facilityBean.facilityForEdit.rfsAcctLedger}"
label="RFS Account Ledger" />
</rich:validator>
</h:panelGrid>
</ui:define>
<!-- Buttons that performs actions on a selected record -->
<!-- or navigate to a relevant screen -->
<ui:define name="buttons">
<h:commandButton id="submitButton" value="#{property.submitLabel}"
action="#{facilityBean.save}" styleClass="wideButton"
onclick="#{rich:component('progressWaitModalPanel')}.show()" />
<h:commandButton id="closeButton" value="#{property.closeLabel}"
action="#{facilityBean.close}" styleClass="wideButton"
immediate="true" />
<rich:popupPanel id="progressWaitModalPanel" modal="true">
<f:facet name="header">
<h:outputText value="Processing your request ...." />
</f:facet>
<h:panelGrid columns="1"
style="width: 100%; border-width: 0px; text-align: center;">
<h:outputText value="Please wait..." styleClass="dataValueStyle" />
</h:panelGrid>
</rich:popupPanel>
</ui:define>
The result is nothing. No higlight. No clue what's going on. Have I missed any installation step? I have the css and xmlnamespace in place. Anything else?
I tried to add required="true" as it was shown in the example, but that did not work either. Not sure whether it is due to richfaces bean validation issue.
The <o:highlight> works server side, based on a.o. UIInput#isValid() in JSF component tree. The <rich:validator> works client side and doesn't manipulate JSF component tree.
This indeed doesn't go well together.
I briefly looked into the HTML/JS code of the <rich:validator> showcase and it appears that they don't add a marker style class to the input elements when it's invalid (e.g. PrimeFaces does), so it's going to be hard to write a workaround when continuing the <rich:validator> approach.
You've basically following options:
Maunally write an oncomplete script which finds the validation error messages and then finds the associated inputs and then set the desired marker style class on it.
Report an issue to RichFaces guys and ask them to add a marker style class to invalid inputs via <rich:validator>, so you could style them individually.
Drop <rich:validator> and replace it by server side validation via <f:ajax>.
I have a p:dialog and there is a panel inside it. The problem is "Save" button's action method is not working. It doesn't even calls the method. I can reach the method def. with ctrl+lm so there is no problem with method name.
<h:body>
<h:form id="createAppUserForm" prependId="false">
....
<p:dialog id="newRoleDialogId"
header="Add New Role"
resizable="true"
draggable="true"
widgetVar="newRoleDetailsDialog"
appendToBody="true"
>
<p:panel id="newRoleDialogPanel">
<p:panelGrid id="newRoleDialogPanelGrid" columns="2" style="width: 100%" styleClass="panelGridWithoutBorder">
<h:outputText value="Role Name :"/>
<p:inputText value="#{createAppUserController.selectedRole.name}"/>
<h:outputText value="Role Desc :"/>
<p:inputText value="#{createAppUserController.selectedRole.description}"/>
</p:panelGrid>
<center>
<p:commandButton value="Save"
update="roleListDataTable newRoleDialogPanelGrid growlCreateAppUser"
oncomplete="if (!args.validationFailed) newRoleDetailsDialog.hide()"
action="#{createAppUserController.saveNewRole()}"/>
<p:commandButton value="Cancel"
immediate="true"
onclick="newRoleDetailsDialog.hide()" />
</center>
</p:panel>
</p:dialog>
</h:form>
</h:body>
The dialog, when used with an appendToBody/appendTo="#Body" must have its own form.
<p:dialog>
<h:form>
...
</h:form>
</p:dialog>
Because, when the dialog is generated into HTML output, it's by JavaScript relocated to the end of HTML <body> which causes it to not be sitting in any form anymore. The generated HTML DOM tree ends up to look like this (use webbrowser's dev tools to see it):
<body>
...
<form id="createAppUserForm">
...
</form>
...
<div id="newRoleDialogId" class="ui-dialog ...">
...
</div>
</body>
The appendToBody="true" plays a role in here. The end of body ensures easy and best cross browser compatibility of displaying a modal dialog by JavaScript.
The same is true by the way for a p:overlayPanel with an appendTo...
But also make sure there is, before 'moving' the p:dialog, there is not a nested h:form. So prevent
<h:form>
...
<p:dialog>
<h:form>
...
</h:form>
</p:dialog>
...
</h:form>
Since although it ends up like
<body>
...
<form id="createAppUserForm">
...
</form>
...
<div id="newRoleDialogId" class="ui-dialog ...">
<form>
...
</form>
</div>
</body>
it is initially invalid html

Adding (process="#this") to commandButton worked for me.
try this p:remoteCommand

this is my example
<h:commandButton value="Aceptar" type="button" onclick="irAConf()" class="art-button">
</h:commandButton>

action="#{configuracionBean.irAConfiguracion}"/>
The appendToBody="true" plays a role in here. This attribute have been removed from in latest version. Please look for other alternative
I'm having a issue with JSF / Primefaces to display the popup.
As a background, I'm using JSF templates to generate my pages:
The inline works to show the datatable but when I click the button to show the dialog nothing happens. I don't see any error in the logs.

I'm following the oficial primafaces showcase PrimeFaces datatable
I'm current setup is Netbeans 7.3 RC1 / Apache 7.0.34.0 / Mojarra 2.1.13
I'll appreacite if someone could point me to the right direction to solve this :)
EDIT: After taking account the answer inline nothing works.
Maybe I should had checked first the brower console, and in this case it's weird cause it complains that it does not recognize the widgedVar.
I already tried to put the Dialog outsite the form and the result is the same error. :/
Your bttAdd button is ordinary push button (you set it explicitly with type="button" attribute). This means it just do some JavaScript, without any AJAX requests. To do an AJAX request, and update your panel remove type="button" and try than.
I would change 2 things (first maybe not important):
Add 2 forms: one with data table inside and another inside dialog
change widgetVar="userDialog" to something unique. widgetVar="userDialogWidget"
Found the issue ...
After lots of tests and digging and taking into account the previous answers. The problem was two things:
1st. The diagonal height and width cannot have px in it.
2nd. And as per previous answers, it has to be outside as
here explained.
The p:dialog cannot have px in the sizes.
I'm working with jsf2 and want to use the ajax-functionality of it. Problem: I've already seen some ajax refresh things. But nothing to refresh a whole div...
I have a xhtml page with data from my bean, and i don't really want to refresh all fields of it, it would be easier to refresh the whole ui:include...
does anybody knows a solution? Or do I have to refresh all fields manually?
best regards
Just put them in some container component with an ID and use it in render attribute of f:ajax.
<h:form>
<h:commandButton value="submit" action="#{bean.submit}">
<f:ajax render=":foo" />
</h:commandButton>
</h:form>
<h:panelGroup id="foo" layout="block">
<ui:include src="include.xhtml" />
</h:panelGroup>
Note that <h:panelGroup layout="block"> renders a <div>. If you omit the layout attribute, it defaults to <span> (only whenever there are any attributes which needs to be rendered to HTML, like id).
Okay BalusC, but I'm still having a problem with the includes and ajax.
my index.xhtml includes a search.xhtml and a results.xhtml
the ajax-part is in search.xhtml and the toRender-id is in results.xhtml...
so at rendering the jsf-tags there's the problem that there's no toRender-Id at this time...
EDIT:
Okay the problem was not the arrangement of the includes, it was that the ajax-parts must be in the same form tag like this:
<h:form>
<div id="search" class="search">
<ui:insert name="search" >
<ui:include src="search.xhtml" />
</ui:insert>
</div>
<h:panelGroup id="ajaxResult" layout="block">
<ui:insert name="searchResults" >
<ui:include src="searchResults.xhtml" />
</ui:insert>
</h:panelGroup>
</h:form>
search contains f:ajax tag, ajaxResult is toRenderId
