I have this button in a .xhtml:
<p:commandButton id="openDialog"
value="#{msg.CreateMultiple}"
onclick="PF('dialogLocations').show();" title="View"
type="button">
</p:commandButton>
What it is supposed to do, is to open the dialog dialogLocations which has the next code:
<p:dialog header="#{msg.CreateMultiple}" id="dialogLocations"
widgetVar="dialogLocations" modal="true"closable="true"
dynamic="true" closeOnEscape="true">
<h:form>
<p:commandButton id="acceptMultiple_button" value="#{msg.Create}"
action="#{locationCreateBean.createMultiple(true)}"
styleClass="btn-green internal-margin-left" update="#form">
</p:commandButton>
<p:commandButton id="cancelMultiple_button"
styleClass="btn-red internal-margin-left"
onclick="PF('dialogLocations').hide();" value="#{msg.Cancel}"
title="View" type="button">
</p:commandButton>
</div>
</h:panelGroup>
</h:form>
</p:dialog>
The dialog has some inputs also to use in the bean.
My problem is that, when I click the button "openDialog" the dialog opens and the method locationBean.createMultiple(true) is being called, which is the action of the button "acceptMultiple_button" .
Shouldn't the action of the button be triggered when I click the button?
Thanks.

Solved it. It was a comment on the xhtml surrounded by <!-- --> that has the call to the method. I thought that in a comment wouldn't call the function. But it seems sometimes it calls a comment anyway.
Thanks for the comments.

I'm using PrimeFaces 5.3 with the following code:
<p:dialog id="dlg1" appendTo="#(body)" header="Confirm Dialog" widgetVar="dlg1" modal="true">
<h:form id="dialogform">
<h:outputText id="confirmlabel" value="Are you Sure you want to #{reportRunnerNamedBean.currentCommand} ?" />
<br/>
<center>
Check to send only missed emails:<p:selectBooleanCheckbox id="sendOnlyMissedBox" value="#{reportRunnerNamedBean.sendMissedOnly}"></p:selectBooleanCheckbox><br/>
<p:commandButton id="yesButton" value="Yes" action="#{reportRunnerNamedBean.runCurrentCommand()}" onstart="startWait();PF('waitDialog').show();" oncomplete="PF('waitDialog').hide();stopWait();" onclick="PF('dlg1').hide();" process="#form"/>
<p:commandButton id="noButton" process="#this" value="No" onclick="PF('dlg1').hide();"/>
</center>
</h:form>
</p:dialog>
No matter what, the backing bean value for the sendMissedOnly is set to false. I have confirmed this by attaching a debugger. I have even tried adding ajax to the box, it is still false every time, no matter if it is checked or not. Does p:selectBooleanCheckbox just not work in a dialog?
I figured this out. It was because the dialog was in an form. It seems that when a dialog is in a form , and you have a form within the dialog itself, the component will not be processed. It seems JSF/primefaces does not like multiple layers of forms or dialogs defined within forms. If you are having a similar issue, makes sure your dialog is defined outside any form. Moving a dialog can cause paths to components to change. the easiest way to resolve that is to use the primefaces handy p:component tag like this update=":#{p:component('compoment_name')}" > that will make it find it no matter where in the tree the component occurs.

Primefaces commandLink works but not commandButton [duplicate]

This question already has answers here:
Differences between action and actionListener
(4 answers)
Closed 6 years ago.
I have identical actions for commandLink and commandButton. However, commandLink works as expected. But with commandButton no action occurs. Am I missing syntax?
<p:commandLink value="Submit" action="#{beanController.getStr(strSearch)}" ajax="false"/>
<p:commandButton value="Submit" actionListener="#{beanController.getStr(strSearch)}" ajax="false"/>
If you intend for navigation to occur you should use action not actionListener in your commandButton, so:
<p:commandButton value="Submit" action="#{beanController.getStr(strSearch)}" ajax="false"/>
commandButton button generates a HTML <input type="submit"> element and the commandLink generates a HTML <a> and comandButton is using to submit the form whereas commandlink is used to submit a link,so your form is not submitting i'll suggest you to check if there is any nested form is present or not or if there is multiple forms in your code or any other issue which is causing in form submit, if you can then post your code.

a4j:commandButton's action is never triggered when it's inside a rich:panel with rendered tag [duplicate]

This question already has answers here:
commandButton/commandLink/ajax action/listener method not invoked or input value not set/updated
(12 answers)
Closed 8 years ago.
Here is the simplified version of my xhtml code, I can't figure out why my save1 commandButton doesn't work while save2 works:
<rich:panel id="table_panel">
<h:form>
<rich:panel rendered="#{bean.showPanel}">
<a4j:commandButton id="save1" value="Save"
action="#{bean.executeAction()}">
</rich:panel>
<rich:panel>
<a4j:commandButton id="save2" value="Save2"
action="#{bean.executeAction()}">
</rich:panel>
</h:form>
</rich:panel>
When click a button, it will update showPanel value to true in backend and re-render *table_panel*,
then commandButton save1 will show up, but even if it show up, the action executeAction()
will never be invoked after click (never enter into my breakpoint in the method). However, the commandbutton save2 can always act normally.
The only difference for those two buttons is their wrapper rich:panel, one is always there while
another is displayed after some UI action as it has rendered="#{bean.showPanel}" attribute. I didn't see any javascript errors on firebug.
I would appreciate any ideas, thanks in advance!
Try putting execute="#this" explicitly in the commandButton.
Have you tried immediate="true", it might narrow down the issue in my opinion:
<a4j:commandButton id="save1" value="Save" immediate="true"
action="#{bean.executeAction()}">

I'm getting wrong or what, the same code for p:fileUpload works fine, but when I put p:fileUpload into p:dialog, it is not working.
<p:dialog id="confirmDialog" appendToBody="true"
header="MAJ Fichier FMD" widgetVar="confirmation">
<h:form enctype="multipart/form-data" >
<h:panelGrid columns="1" cellpadding="5">
<p:fileUpload
auto="true"
fileUploadListener="#{parserXls.handleFileUploadFMD()}"
sizeLimit="2097152"
label="Choose"
allowTypes="/(\.|\/)(pdf)$/"
description="Images"/>
<p:commandButton id="OK" value="OK" onclick="confirmation.hide()" type="button" />
</h:panelGrid>
</h:form>
</p:dialog>
What is the problem here?
The situation looks like a nested forms problem - if it is so, remove the inner form and try again.
Well i had the same problem and it wasn't nested forms problem. I was using action instead of actionListner.
For those who still have the problem, check if you not forget to put (
enctype="multipart/form-data") inside the form.

JSF Delete entity on DataTable with p:dialog [duplicate]

This question already has answers here:
p:commandbutton action doesn't work inside p:dialog
(4 answers)
Closed 6 years ago.
I'm currently working on a CRUD form and is now working on the last part which should be the most easiest - delete. But I want to show a dialog before the user can do the actual deletion. And this is where I'm having problem with Primefaces 3.4. For some reason I cannot set the action in the button inside the p:dialog, ajax=false failed. So here's what I did:
<p:column headerText="#{msgs['action.delete']}"
styleClass="a-center">
<p:commandButton icon="ui-icon-trash"
oncomplete="confirmation.show()">
<f:setPropertyActionListener
target="#{marketingCodeBean.marketingCode}" value="#{code}"></f:setPropertyActionListener>
</p:commandButton>
</p:column>
The Dialog:
<p:confirmDialog id="confirmDialog"
message="#{msgs['message.marketingCode.confirmDelete']}"
header="#{msgs['common.confirmDelete']}" severity="alert"
widgetVar="confirmation">
<p:commandButton id="confirm" value="#{msgs['common.yes']}"
oncomplete="confirmation.hide()" update=":form:mktgCodeTable"
actionListener="#{marketingCodeBean.remove}" />
<p:commandButton id="decline" value="#{msgs['common.no']}"
onclick="confirmation.hide()" type="button" />
</p:confirmDialog>
I'm aware that the actionListener should not be use for business action, but I can't think of a workaround given the datatable and the dialog. Any idea on how I can make ajax=false in p:commandButton inside p:confirmDialog?
Once rendered, the dialog's HTML output is by some onload JavaScript relocated to end of HTML <body> in order to achieve the best cross-browser compatible overlay/positioning. However, this thus means that if it was placed inside a <form>, it would not be in a <form> anymore and synchronous (non-ajax) requests would then not work anymore. This is not exactly an action vs actionListener issue.
The <p:dialog> (and <p:confirmDialog> as you seem to be actually using) should have its own <h:form> component.
<h:form>
<p:dataTable>
...
</p:dataTable>
</h:form>
...
<p:confirmDialog>
<h:form>
...
</h:form>
</p:confirmDialog>
