Someone who have used Primefaces 4.0-SNAPSHOT may have noticed the following warning.
The appendToBody attribute of the ConfirmDialog will be deprecated in
future versions. Please use appendTo="#(body)" now
Along with Primefaces 4.0 RC1, I have this piece of code.
<h:body>
<h:form prependId="true" id="form">
<p:confirmDialog id="confirmDialog"
widgetVar="confirmDeleteMultiple"
message="Message"
showEffect="true"
hideEffect="true"
header="Header"
severity="alert"
closeOnEscape="true"
appendTo="#(body)" <-----------------
closable="true">
<p:commandButton id="btnYes"
value="Yes"
process="#this"
oncomplete="confirmDeleteMultiple.hide()"/>
<p:commandButton id="btnNo"
value="No"
onclick="confirmDeleteMultiple.hide()"
type="button" />
</p:confirmDialog>
<p:commandButton oncomplete="confirmDeleteMultiple.show()"
update=":form:confirmDialog"
actionListener="#{testManagedBean.insert}"
ajax="true" type="submit" value="Submit"/>
</h:form>
</h:body>
When the only command button on the page is clicked, the dialog appears with the two buttons given.
On pressing any of these buttons, the dialog disappears but leaving the background opacity. The background opacity loses only when the page is reloaded.
Why does this happen with this new version? Any suggestion? In earlier versions, this was just fine.
It is associated with showEffet and hideEffect attributes of confirm dialog - from PrimeFaces Forum.
There is a misuse of effect attributes, "true" is not a valid value,
should be bounce, fade ... 4.x is more strict about wrong attribute
values

I have this code:
<h:form>
<h:button value="SHOW" onclick="PF('myPanel').show()" />
<p:dialog header="MyPanel" widgetVar="myPanel">
<h:outputText value="Resistance to PrimeFaces is futile!" />
</p:dialog>
</h:form>
Clicking the button only flashes the dialog -- opens and immidiatelly closes it. Also tried using JSF commandButton with same result. Using a primefaces button works as expected, so what is JSF button missing here?
use <p:commandButton> instead.
<p:commandButton value="Basic" type="button" onclick="PF('dlg1').show();" />
I need a rich:popup that shows a rich:extendedDataTable, and when the user presses a button, the popup should be shown, and the extendedDataTable must be re-rendered, here is the code:
<rich:popupPanel id="popupId" show="false" modal="true">
<h:form>
<rich:extendedDataTable
value="#{bean.list}"
var="item" rows="5" id="table">
<rich:column>
<h:outputLabel value="#{item}" />
</rich:column>
</rich:extendedDataTable>
<a4j:commandButton value="x" immediate="true"
oncomplete="#{rich:component('popupId')}.hide(); return false;"/>
</h:form>
</rich:popupPanel>
<h:form>
<a4j:commandButton value="show"
oncomplete="#{rich:component('popupId')}.show(); return false;"
render="table" immediate="true" />
</h:form>
The first time I press the show it works fine, but when I close the panel with the X button and press again the show button, the extendedDataTable appears empty (It's rendered but appear empty, see image below).
The problem is fixed if I add an empty extendedDataTable before the popup, like this:
<rich:extendedDataTable />
<rich:popupPanel>
...
With rich:dataTable the problem doesn't exits, but I need a extendedDataTable.
And aditional extrange behaviour is when I resize the browser, the data appears.
Platform
RichFaces: 4.2.2.Final
Spring: 3.1.1.RELEASE
Cheers
Use onclick instead of oncomplete. ExtendedDataTable doesn't render properly inside invisible elements (it's a bug) so the popupPanel has to be made visible before the rerendering.
I had kinda the same issue.
I solved it in a not 100% richface correct way:
<a4j:commandButton
value="show"
action="#{actionForm.setShowEditor('true')}"
oncomplete="javascript:location.reload(true)"/>
<a4j:region layout="block" rendered="#{actionForm.showEditor}" id="panelArea">
<rich:popupPanel id="#{popupID}" modal="true" show="true" domElementAttachment="parent">
....
tabel
buttons
....
</rich:popupPanel>
</a4j:region>
The popup is always shown (show="true") inside the a4j:region.
But the a4j:region is only shown if variable to show the popup = true.
The full page refresh was in my case needed because otherwise my ckeditor had some initialisation errors. It should also work if you only rerender the a4j:region after you set the "#{actionForm.setShowEditor('true')}.
I have a commandButton and a dialog. The problem is after the dialog box appears, it disappears(1-2 miliseconds later). Is there a problem with my commandbutton or its dialog issue?
<p:commandButton id="showDetailsButton"
title="Details"
onclick="details.show();"
process="#this"
update=":tabView:myForm:myDialogId"
icon="ui-icon-search">
</p:commandButton>
<p:dialog id="myDialogId"
header="Details"
widgetVar="details"
resizable="false"
height="600"
width="450"
>
//some stuff
</p:dialog>
Changed onclick to oncomplete and now It's working perfectly.
<p:commandButton id="showDetailsButton"
title="Details"
oncomplete="details.show();"
process="#this"
update=":tabView:myForm:myDialogId"
icon="ui-icon-search">
By default a <p:commandButton> is rendered as
<button type="submit" ....> ... </button>
EDIT: Iff you've disabled ajax behavior by specifying ajax=false, please read comments below.
and hence it will trigger a Post Back. So your page makes a POST request to server and refreshes.
Btw, you don't need a PrimeFaces commandButton here, simply use
<input type="button" onclick="details.show()" value="Details"/>
remove the process and update from your commandbutton. They refresh the page/section. And you don't want that.
I have the following code inside a registration form. Basically the button calls an action (an Ejb method and an Action listener which is an utility method).
When the user submits the registration form, a primefaces dialog should appear telling the user that registration is being processed. The same dialog disappears once the form is submitted. This can be achieved by Primefaces UIBlock; however, it requires the commandButton to be ajax enabled.
I thought about using : onstart = display some modal dialog & onsuccess or on complete = hide this dialog (<p:dialog widgetVar="dialog" ...) but this solution requires ajax to be enabled for primefaces commandButton.
Any clues on how I could achieve this while setting ajax to false inside a PrimeFaces commandButton?
Thanks
<h:form id="form_register">
<p:panel id="panel_register">
<div align="center" style="padding: 5px;">
<p:commandButton id="register" ajax="true"
actionListener="#{mailBean.deliverEmail(newMember.email,newMember.name, newMember.username, newMember.password, newMember.isadmin)}"
action="#{memberController.register}" value="Register"
label="Register">
<f:setPropertyActionListener target="#{requestScope.wait}"
value="#{true}" />
</p:commandButton>
</div>
<p:blockUI block="panel_register" trigger="register">
<h:outputText value="Please wait..." />
<br />
<p:graphicImage value="#{resource['gfx/gif.gif']}" />
</p:blockUI>
EDIT: Thanks guys. I was mis-using the update the attribute in commandButton. Now things work fine.
You should use the onstart and oncomplete actions to display/hide the dialog.
<p:commandButton id="register" onstart="dlg.show()" oncomplete="dlg.hide()" />
I have a dialog that contains no content on page load and I'm dynamically setting the content of a dialog box based on the link that a user clicks on.
<p:dialog widgetVar="dlg" modal="true" id="dialog">
<p:panel id="fullArticle">
<h:outputText value="#{content.newsArticle}" escape="false" />
</p:panel>
</p:dialog>
...
...
<p:commandLink value="Read more" actionListener="#{content.getFullArticle}" onclick='dlg.show();' update=":fullArticle">
<f:attribute name="contentId" value="#{news.contentId}" />
</p:commandLink>
The problem i'm having is that when you click the "Read More" link, it shows the dialog, but the dialog is not centered on the page. If i change the udpate attribute on the commandLink to update=":dialog", the dialog flashes as if it's opening and then closing right away.
How can I update the dialog and have it be centered with dynamic content?
The onclick is executed before the ajax request. You need to open the dialog in oncomplete instead. This will be executed after the ajax request and update. The <p:dialog> is namely by default hidden unless its visible attribute evaluates true.
<p:commandLink value="Read more" actionListener="#{content.getFullArticle}"
update=":dialog" oncomplete="dlg.show()">
Unrelated to the concrete problem, are you aware that you can pass fullworthy objects as method arguments since EL 2.2? This makes the <f:attribute> and actionListener "hack" superfluous:
<p:commandLink value="Read more" action="#{content.getFullArticle(news)}"
update=":dialog" oncomplete="dlg.show()" />
I had the same problem.
Updating the dialog makes it disappear and reappear (and forget its position).
To solve it, I created a wrapper tag around the dialog content.
<p:commandLink update=":playerViewDialogHeader,:playerViewDialogContent"
oncomplete='playerViewDialogJS.show()' value='#{item.name}' />
<p:dialog id='playerViewDialog' widgetVar='playerViewDialogJS'>
<f:facet name="header">
<h:outputText id="playerViewDialogHeader" value="#{playerController.objectView.name}" />
</f:facet>
<h:form id='playerViewDialogContent'>
<!-- CONTENT GOES HERE -->
</h:form>
</p:dialog>
