JSF h:messages render global message is not rerendered

Question

I'm trying to display global error messages which are sent from EJB with:

FacesContext.getCurrentInstance().addMessage(
                    null,
                    new FacesMessage(FacesMessage.SEVERITY_ERROR,
                            "Please select a path first", "title"));

right now the JSF has the following code:

<h:messages globalOnly="true"/>

The above however doesn't work because the JSF page is not rerendered. Notice I am able to make the above work using primefaces, if I substitute the JSF code with the following:

<p:messages globalOnly="true" showDetail="true" autoUpdate="true" closable="true" />

However I don't want to use primefaces and I want a pure JSF solution. Notice also I don't want the h:messages to be inside a form as there's no button to click, I want the h:messages to be auto updated from the EJB but without using primefaces.

Just in case, you can also use a `` with `AJAX` to update a `` which does not contain `autoupdate="true"` — alexander, Aug 18 '15 at 07:41

You have to render the <h:messages /> else it wont show. You can achive this by rendering the message from the managedbean.

<h:messages id="globalMessage" />

And in your managedBean you place a code to render the messages after your

FacesContext.getCurrentInstance().addMessage(
                null,
                new FacesMessage(FacesMessage.SEVERITY_ERROR,
                        "Please select a path first", "title"));

FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds()
.add("globalMessage");

But be sure you have the correct Id to be rendered.
