The <p:commandButton> sends by default an ajax request wherein by default the entire form is executed (as in process="@form"), but by default actually nothing will be updated (as in update="").

If you want to update the UI on complete of the ajax request, then you need to explicitly specify the update attribute. For example, this updates the entire form:

<p:commandButton ... update="@form" />

And this updates only a specific component:

<h:messages id="messages" ... />
<p:commandButton ... update="messages" />
<p:messages>
<p:messages ... autoUpdate="true" />
<p:commandButton ... />

The <p:confirmDialog> has already generated its HTML representation on the very first HTTP request returning the page with the form and the dialog. It's merely hidden by CSS and is supposed to be shown/hidden by JS. When you change the confirm message afterwards in a bean action method, then it won't be reflected in the generated HTML output as long as you don't ajax-update it.

So, in order to get the changed message being reflected, you'd need to update the HTML representation of the <p:confirmDialog> in the client side before showing it in the oncomplete. You can for this use the update attribute of the command button which should show the dialog.

<p:commandButton ... update="confirmDialog testPlanetree">

The reason your example only works when pushing the button is that you're updating the growl element.

You can do two things to make sure you keep getting new messages.

When using push the server pushes updates to the client when necessary. PrimeFaces has some examples that may help you realize push. I don't know if this works on all browsers though.

Using polling the client periodically checks for updates (can generate a lot of network traffic). PrimeFaces has a poll element to make things easier, have a look at the example. AFAIK it uses JavaScript so it should work on most modern browsers.

How to display messages from Java buffer in JSF pages using Primefaces...

java jsf jsf-2 primefaces

That gets tricky if the both <p:messages> components have an autoUpdate="true". It would be doable if only the page's <p:messages> is auto-updated. If you can ensure that the page's <p:messages> appears in JSF component tree after the dialog's <p:messages>, then it's a matter of setting the redisplay attribute of page's <p:messages> to false and making sure that each of the dialog's actions updates the dialog's own form with therein the <p:messages>.

<p:dialog>
    <h:form>
        <p:messages />
        ...
        <p:commandButton ... update="@form" />
    </h:form>
</p:dialog>
<p:messages autoUpdate="true" redisplay="false" />

No additional JS is necessary. You may only need to alter your templates to have an <ui:define name="dialogs"> above the page's <p:messages> so that all your dialogs end up there. Or, alternatively, use CSS to position the page's <p:messages> absolutely. Or, maybe, use JS to relocate the page's <p:messages> to there where you'd like to have it in HTML DOM.

Right, that indeed doesn't work if the dialog's <p:messages> has also an autoUpdate="true". Is it acceptable to just put it inside a form and perform update="@form" in any of the dialog's commands? Perhaps you already have those? I've updated the answer.

This is actually a separate problem and not the standard behavior. Perhaps you've a dialogWidgetVar.hide() in oncomplete or so? Or you actually placed the form outside the dialog?

Form must always go inside the dialog, not only for this reason, but also to avoid failing synchronous submits because the dialog is by default by JS relocated to end of the body.

Shouldn't happen. Did you alter the PrimeFaces dialog CSS? Otherwise try if <p:dialog appendToBody="true"> works for your specific problem. If in vain, show an SSCCE.

Note that I've simplified your code in order to avoid using a managedbean.

If you want your managed bean to perform the validation, use RequestContext to conditionally execute the code that will close the dialog and remove the oncomplete from Submit button.

if (success) {
    RequestContext.getCurrentInstance().execute("dlg.hide()");
}else{
    //show all the messages you need here
}

Whenever an UICommand component (<h:commandXxx>, <p:commandXxx>, etc) fails to invoke the associated action method, or an UIInput component (<h:inputXxx>, <p:inputXxxx>, etc) fails to process the submitted values and/or update the model values, and you aren't seeing any googlable exceptions and/or warnings in the server log, also not when you configure an ajax exception handler as per Exception handling in JSF ajax requests, nor when you set below context parameter in web.xml,

<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>

and you are also not seeing any googlable errors and/or warnings in browser's JavaScript console (press F12 in Chrome/Firefox23+/IE9+ to open the web developer toolset and then open the Console tab), then work through below list of possible causes.

In case you still stucks, it's time to debug. In the client side, press F12 in webbrowser to open the web developer toolset. Click the Console tab so see the JavaScript conosle. It should be free of any JavaScript errors. Below screenshot is an example from Chrome which demonstrates the case of submitting an <f:ajax> enabled button while not having <h:head> declared (as described in point 7 above).

Click the Network tab to see the HTTP traffic monitor. Submit the form and investigate if the request headers and form data and the response body are as per expectations. Below screenshot is an example from Chrome which demonstrates a successful ajax submit of a simple form with a single <h:inputText> and a single <h:commandButton> with <f:ajax execute="@form" render="@form">.

In the server side, make sure that server is started in debug mode. Put a debug breakpoint in a method of the JSF component of interest which you expect to be called during processing the form submit. E.g. in case of UICommand component, that would be UICommand#queueEvent() and in case of UIInput component, that would be UIInput#validate(). Just step through the code execution and inspect if the flow and variables are as per expectations. Below screenshot is an example from Eclipse's debugger.

your 2nd point made me think -- for a long while. I just found out that an f:view tag in my main file was the cause of most of my problems. And probably because it renders a form, right?

@pauloguedes I cant find anything that states that f:view renders a form. My understanding is that it is just a container. In my experience, f:view does not render any elements.

@balusc A little clarification on point 4, if the commandLink is not in the dataTable itself, does it still matter?

Your problem does not match 10. Your problem is that the form in the error page is submitting to an invalid URL. Depending on the functional requirement of those command links, better make them plain links instead, for sure if it's for pure page-to-page navigation.

@Kukeltje: that would have thrown an EL exception (already covered by 1st paragraph in the answer)

How exactly does this answer this question? You didn't explain/describe the solution concretely in any way. You've only shown a piece of code which is mostly similar to the OP's one with the only change being that you used actionListener instead of action. Why exactly do you think that this solves OP's concrete problem? Why exactly didn't you explain the solution in any way and do we have to guess it based on comparing the code?

I have developed, lets say a "nasty" way.

<p:dialog widgetVar="dialog" >
   <p:messages autoUpdate="true" />
</p:dialog>
<p:messages autoUpdate="true" />

OR if you want to apply this on all the dialogs.

$(document).ready(function() {
   $('.ui-dialog').each(function() {
       widgetName = 'widget_' + $(this).attr('id').replace(/\:/g, '_');
       dialog = window[widgetName];

       dialog.cfg.onShow = function onShowDialog() {
           $(".ui-messages").not('.ui-dialog .ui-messages').hide()
       }

       dialog.cfg.onHide = function onHideDialog() {
           $(".ui-messages").not('.ui-dialog .ui-messages').show()
       }
   })
})

and the magic happens.

Note: if you update the dialog, you would lose the events, you need to re-run the script.

Thanks but can it be done using a clean way?

Well, since you have two rendered messages in the same time (one in the main, and another in the dialog) this is the only way of hiding while the dialog is opened... at least for me :)

It doesn't work. Id doesn't regonize the dialog variable. Could you give me please the code of the demo you posted here?

If you want to check if user entered data, you could alternatively use the required attribute of an input field in combination with the requiredMessage field, e.g. for an inputField:

<h:inputText value="#{myBean.beansField}" required="true" requiredMessage="Can not be null"/>

If you want to overwrite messages in general you have to edit or overwrite the messages.properties file:

<locale-config><default-locale>en</default-locale></locale-config>
     <message-bundle>/resources/messages</message-bundle>
  • Put a file called messages_en.properties in your resources folder

Add messages you want to overwrite in this manner:
