p commandbutton action does not fire but oncomplete fires

I am using jsf 2. One part of my code is this:
<h:panelGrid id="jobDetail" columns="3" cellpadding="7">
<p:outputLabel value="#{msg['content.jobList.JobName']}" />
<p:inputText id="jobName" styleClass="BIC_search_textbox" value="#{timerConfigurationBean.selectedTimerConfigurationJob.jobName}" required="true" requiredMessage="#{msg['content.jobNew.requiredfield.errormsg']}"/>
<p:message for="jobName" styleClass="error"/>
</h:panelGrid>
<p:commandButton id="update" value="Update_Button" action="#{timerConfigurationBean.updateExportJob}" styleClass="bottomButtonsAfterFirst" update="jobDetail" oncomplete="PF('updatejobpopup').show()"/>
This is only a section of the code. What happens is that when I click on the command button "Update_Button" one of the following two things happen:
1) I enter a value in inputText "jobName" and click the command button. First the function in action="#{timerConfigurationBean.updateExportJob}" runs and then the oncomplete="PF('updatejobpopup').show()" runs. This is how it was intended to be so that is okay.
2) I don't enter anything in inputtext (it is a required field), then click on the commandbutton. I see an error message on the webpage next to the Inputtext field (this happens because I have update="jobDetail" in my commandButton) and action="#{timerConfigurationBean.updateExportJob}" is not run however the oncomplete="PF('updatejobpopup').show()" still runs. This is a problem.
I want the oncomplete to only run when there are no errors on the page just like the function in action="#{timerConfigurationBean.updateExportJob}".
Can someone please help.

You can use the callback of primefaces to give a feedback to the view.
So, in your action method yo can do:
context.addCallbackParam("ok", true);
And in the onComplete:
oncomplete ="if ( args.ok ) { PF('updatejobpopup').show(); }"

How to delay a commandLink in jsf with javascript or primefaces?

I have a commandLink which calls a backend page bean method. but I want to make a delay before it calls that method. How to do this using javascipt or primefaces?

PrimeFaces offers p:remoteCommand. It can be called via javascript and execute, do action and ajax process and updates. Use the p:commandLink to call a javascript function with a timeout. In short
<p:commandLink onclick="delayIt()" />
<p:remoteCommand name="remoteCommandName" ... action ... update ... process/>
<script type="text/javascript">
var delayIt = function(){
setTimeout( remoteCommandName,5000) //don't write () as it would execute it immediately
}
</script>

In primefaces try 'delay' as attribute. delay is null as default.
<p:commandLink id="clid" actionListener="#{buttonView.buttonAction}" delay="1000">
<h:outputText value="text" />
</p:commandLink>

How do I conditionally display a Javascript alert() that blocks the page from submitting until the user clicks "OK"?

I have a commandButton like this:
<p:commandButton value="Save" actionListener="#{bean.checkDetails}" action="#{bean.save}" />
My checkDetails() method checks some fields on the page and if they are not filled in, uses RequestContext to trigger a Javascript alert() which I want to use to block bean.save from being called until the user clicks "OK". The RequestContext piece looks like this:
RequestContext context = RequestContext.getCurrentInstance();
context.execute("alert('Details are not Complete.')");
My problem is I am not seeing the alert() dialog and bean.save is being called regardless of the state of the checkDetails() method.
Am I going about this completely the wrong way? I have spent three hours on this so far and I am plain stuck. If I remove the action method, the alert() pops up just fine.
Please, any input would be greatly appreciated.

My checkDetails() method checks some fields on the page and if they are not filled in...
As BalusC said, this can very easily be solved by adding required="true" to those fields, no need to write Java for this.
If you want to mix this up with the 'old-scool' alert() you can use the validationFailed callback parameter:
<h:form>
<p:inputText required="true" />
<p:commandButton value="submit" oncomplete="handleValidation(xhr, status, args)" />
</h:form>
<script type="text/javascript">
function handleValidation(xhr, status, args)
{
if(args.validationFailed)
{
alert('Details are not Complete.');
}
}
</script>

How to generate click event of panelgrid through jquery or javascript?

I am using JSF 2.0 and primefaces 3.0. I have a rowtoggler and rowexpansion. Since I am using primefaces old version so I dont have rowToggle event. And I need to call a method on server side through ajax at the time of row expansion. So I have put div tag around rowtoggler and calling a javascript function. Now I want to initiate ajax call through click event of panelgrid which is inside rowexpansion. If this happen then it would look like 3.4 rowToggle event.

You can use jQuery's event binding to execute Javascript when clicking on the row toggler.
<h:form id="form">
<p:dataTable id="dt" value="[1,2]">
<p:column>
<p:rowToggler />
</p:column>
</p:dataTable>
<p:remoteCommand name="remotecommand"
oncomplete="alert('remote command fired')" />
</h:form>
<script type="text/javascript">
$("[id='form:dt'] .ui-row-toggler").on("click", function() { remotecommand(); });
</script>
Explanation of Javascript:
The $("[id='form:dt'] .ui-row-toggler") selects the datatable by id (form:dt) and then selects all descendants that have the style class ui-row-toggler.
The .on("click", function() { remotecommand(); }) binds an anonymous function to a click event which fires a Javascript function declared by p:remoteCommand.
You can use the p:remoteCommand to execute bean methods with it's action or actionListener. ;-)
Note that this I don't find this to be a long term solution. Upgrading to PrimeFaces 3.4 would be a better solution.

I have put commandLink arround rowtoggler and I make ajax call through commandlink and I can also pass value through it using EL2.2
<p:commandLink action="#{myBean.doSomething(foo)}" >
<p:rowToggler/>
</p:commandLink>

I guess you'd something like
<p:panelGrid>
<p:ajax event="click" listener="#{bean.onclick}" />
...
the rest of the grid here
...
<p:panelGrid>
I haven't tested it but it works for other components

Except solution of siebz0r I found one more solution.
<p:commandLink action="#{bean.abcFunction}"> <p:rowToggler/> </p:commandLink>
it also works and simple too :-)

Javascript calling JSF handler method

I am reading an xml file using javascript and then I need to submit my form so that it calls a particular method in my JSF handler. Usually this can be done on a jsp when user clicks a button by having an actionlistener like so:
<h:commandLink styleClass="button" action="#{myHandler.outcome}" actionListener="#{myHandler.doNext}">
<span><h:outputText value="#{text.button_submit}" /></span> </h:commandLink>
I am not sure how to call a method like 'doNext' above in the handler from javascript. I cannot do a simple:
document.form.submit();
as it then repeats the processing i have already done. I want to read values from an xml file and then call a particular method in handler. Any ideas much appreciated.

I found a solution to this. I added a hidden button to my jsp like:
<p id="hiddenButton" style="display:none;" >
<h:commandLink id="hiddenRegButton" styleClass="button" action="#{myHandler.doNext}" />
</p>
and in my javascript I used jQuery to execute the click which leads t the "doNext" method in my Handler to get executed.
jQuery('#hiddenRegButton').click();
this was easier than I thought.
