I've the below dialog:
<h:form id="r1">
<p:commandButton value="Basic" type="button" onclick="PF('dlg1').show();" />
<p:dialog header="Basic Dialog" widgetVar="dlg1">
<h:outputText id="test" value="Welcome to PrimeFaces" />
</p:dialog>
</h:form>
How can I refresh the JSF page after closing the dialog?
The <p:dialog> supports the ajax close event. This only requires it being placed inside a <h:form> (on contrary to the general recommendation), so you need to make sure that it's already manually poisitioned to the very end of the <h:body> and that you don't make use of appendToBody.
<h:body>
<h:panelGroup id="content" layout="block">
...
</h:panelGroup>
...
<h:form>
<p:dialog>
<p:ajax event="close" update=":content" />
...
</p:dialog>
</h:form>
</h:body>
Use if necessary update="#all" if you intend to update the entire page. But better is to update only the parts which really need to be updated.

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):
<ui:composition

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 a <p:dialog dynamic="true"> which is shown on start of <p:commandButton>.
<h:form id="form">
<p:commandButton value="#{bundleComunes.guardar}" actionListener="#{saveBB.save}" onstart="PF('saveDialog').show()" update="#form" oncomplete="PF('saveDialog').hide()" />
<p:dialog dynamic="true" widgetVar="saveDialog">
Guardando<br></br>
<p:graphicImage value="/img/ajaxloadingbar.gif" />
</p:dialog>
</h:form>
It shows dialog, but never hides on complete. But if I remove dynamic="true", it works.
<h:form>
<p:commandButton ... update="#form" />
<p:dialog dynamic="true">
...
</p:dialog>
</h:form>
You're updating the form the dynamic dialog is sitting in, causing it to get corrupted because it's after the update not the same dialog anymore as when it was opened.
Change update="#form" to something more specific which does not cover the dialog, or, better yet, move the dialog outside the form, preferably to the very bottom of the body.
<h:form>
<p:commandButton ... update="#form" />
</h:form>
...
<p:dialog dynamic="true">
...
</p:dialog>
I have just tested it on glassfish and it works fine.
I think you should have a look on #{saveBB.save} and check if it throws any exception.
I'm trying to open a new window from dataTable using primefaces. I've tried differents options:
h:commandLink
<h:form id="form" target="_blank">
<p:dataTable id="Table" var="var_row" value="#{bean.table}" sortBy="tableId" >
<p:column>
<h:commandLink action="#{bean.goToPage}" value="Open Page"
onblur="this.form.target='_self'">
<f:setPropertyActionListener value="#{var_row}" target="#{bean.rowSelected}" />
</h:commandLink>
</p:column>
</p:dataTable>
</h:form>
2.p:commandLInk
<h:form id="form" target="_blank">
<p:dataTable id="Table" var="var_row" value="#{bean.table}" sortBy="tableId" >
<p:column>
<p:commandLink action="#{bean.goToPage}" value="Open Page"
onblur="this.form.target='_self'"
process="#this" ajax="false" target="_blank">
<f:setPropertyActionListener value="#{var_row}" target="#{bean.rowSelected}" />
</p:commandLink>
</p:column>
</p:dataTable>
</h:form>
It works, but not correctly. I mean, I get the new page open, but the original page becomes useless, all methods in this pages are not invoked when you clicked on them.
Has anyone experimented this before? Any idea to solve this?
I tried and I still couldn't get a 'commandLink' to open in a new window while at the same time using 'setPropertyActionListener'. I think you have to modify the underlying Primefaces javascript to open in a new window (I didn't try that).
You can try passing a parameter argument.
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
http://www.primefaces.org/showcase/ui/ajax/remoteCommand.xhtml
this is my example
<h:commandButton value="Aceptar" type="button" onclick="irAConf()" class="art-button">
</h:commandButton>
<p:remoteCommand name="irAConf"
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 have some weird issue with datatable selection (most likely i'm doing something wrong).
Idea is simple - datatable with selection and a dialog to edit the records. The problem is that if i use <h:inputText> tag (or <p:inputText>) it appears to be blank, though the object in the backing bean (indicatorBean.indicator.code) contains data. Interestingly if i put <h:outputText> instead of input the data is shown.
here are contents of my body
<!-- language: xml -->
<h:body>
<h:form id="form">
<p:growl id="messages" showDetail="true"/>
<p:dataTable id="indicatorsTable" var="ind"
value="#{indicatorBean.indicators}"
selectionMode="single"
selection="#{indicatorBean.indicator}"
rowKey="#{ind.id}">
<p:column headerText="Name" style="width:125px">
#{ind.name}
</p:column>
<p:column headerText="Code" style="width:125px">
#{ind.code}
</p:column>
<f:facet name="footer">
<p:commandButton id="viewButton" value="View"
icon="ui-icon-search" update=":form:display"
oncomplete="indDialog.show()"/>
</f:facet>
</p:dataTable>
<p:dialog id="dialog" header="Indicator Detail"
widgetVar="indDialog" resizable="false"
width="400" showEffect="fade" hideEffect="fade">
<h:panelGrid id="display" columns="2" cellpadding="4">
<h:outputText value="Code:"/>
<!-- PROBLEM IS HERE -->
<h:inputText value="#{indicatorBean.indicator.code}"/>
<h:outputText value="Name:"/>
<h:outputText value="#{indicatorBean.indicator.name}"/>
</h:panelGrid>
<p:commandButton value="Save" onclick="indDialog.hide()"/>
<p:commandButton value="Cancel" onclick="indDialog.hide()"/>
</p:dialog>
</h:form>
</h:body>
Backing bean is nothing other that accessors.
Another thing i spotted is if i replace el expression in <h:inputtext> with a static text (like <h:inputText value="static text"/>), it is shown.
Here are some pictures:
Dialog with inputtext
Dialog with outputtext
Dialog with static text

The problem as you seem to have already figured out is that you are placing the dialog itself inside of a form. This is an issue because of the way the jQuery dialog control works, which is the client side foundation of the Primefaces dialog. Essentially it will move DOM elements associated with the dialog elsewhere, possibly outside of the form that you intend to enclose it.
This problem can be easily solved by putting the dialog outside of the form, and putting a form inside of the dialog body instead.
<p:dialog id="dialogId" ...>
<h:form id="dlgForm">
....
</h:form>
</p:dialog>
In this way when jQuery UI moves the dialog control elsewhere in the DOM, the contents of that DOM, including the form come with it.
