p:remoteCommand does not invoke the declared action method
Question
Web page:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<h:body>
<ui:composition template="../../Template/template.xhtml">
<ui:define name="content">
<h:form>
<h:outputText id="montest" value="#{ProviderLogin.i}"/>
<button class="ZWButtonActionIntervention pfButtonWhite" type="button" onclick="testpageRC()"/>
<span>TESTING</span>
</button>
<p:remoteCommand name="testpageRC" process="@this" update="montest" action="#{ProviderLogin.TESTING()}"/>
<p:commandButton styleClass="ZWButtonActionIntervention pfButtonOrange" value="#{GestionIntervention.m_typeNonTraitee}" action="#{ProviderLogin.TESTING()}"/>
</h:form>
</ui:define>
</ui:composition>
</h:body>
My java class (Bean)
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
@SessionScoped
@ManagedBean(name="ProviderLogin")
public class ProviderLogin implements Serializable
{
private int i;
public int getI(){return i;}
public void TESTING(){i++;}
}
I have a breakpoint in the function 'TESTING()'
When I press the 'p:commandButton', the breakpoint is reached
When I press the 'button' ( p:remoteCommand is called), the breakpoint is NOT reached
What is really strange, is that the 'p:remoteCommand' works for this: update="montest" But, the method in the bean is not fired.
By the way, when I start to write #{... I have access to my bean (variable and methods)
I use Primefaces 6.2

Problem found.
Every web pages defines the content of a template. In this template there is the section "content" that cointained 2 <h:form> . One is renderer when the user is not logged. The other one is rendered when the user is logged correctly.
In each page that re-define the content (when user is logged), i had a second section of <h:form> . It seems that action of the <p:remoteCommand> doesn't manage this well while <p:button> does. I just deleted that form on each pages and my problem was solved.
My template (content part)
<div id="content" style="padding: 10px">
<h:form rendered="#{!ProviderLogin.m_User.m_bLogged}">
<h:button value="Connexion" outcome="/Gestion/Connexion.xhtml"/>
</h:form>
<h:form id="formContent" rendered="#{ProviderLogin.m_User.m_bLogged}">
<ui:insert name="content" >
<ui:include src="content.xhtml" />
</ui:insert>
</h:form>
</div>
One page that re-define the content part (with 2nd form that gave me errors)
<h:body>
<ui:composition template="../Template/template.xhtml">
<ui:define name="content">
<h:form id="formInterventions">
PAGE CONTENT
</h:form>
</ui:define>
</ui:composition>
</h:body>
The same page that re-define the content part (without 2nd form) then, my action of the <p:remoteCommand> works !
<h:body>
<ui:composition template="../Template/template.xhtml">
<ui:define name="content">
PAGE CONTENT
</ui:define>
</ui:composition>
</h:body>
I also give you this informations:
i use update of some controls like this showcase:
https://www.primefaces.org/showcase/ui/ajax/poll.xhtml
You need to give the id of the control you want to update
When you are using <h:form> , sometimes you need to also specify the id of the form like this:
update="formID:controlID"
Because of that <h:form> defined in my template (which i forgot), it wasn't working because i didn't expect that at all and i didn't give that form an ID, so basically, a default id (j_idt27) was given.
This means my update functionnality couldn't find the specified control id
