<rich:messages> not shown.

[rart3001_1]

Greetings,

I have the following problem. my base template has a section to display messages, but these shows sometimes, and sometimes not. My backend beam inherit from a base class that contains methods to display the following messages:

    public static void addInfoMessage(String msg) {
        addInfoMessage(null, msg, null);
    }

     public static void addInfoMessage(String clientId, String msg, String detalles) {
        FacesContext.getCurrentInstance().addMessage(clientId, new FacesMessage(FacesMessage.SEVERITY_INFO, msg, detalles));
    }

    public static void addErrorMessage(String msg) {
        addErrorMessage(null, msg, null);
    }

    public static void addErrorMessage(String clientId, String msg, String detalles) {
        FacesContext.getCurrentInstance().addMessage(clientId, new FacesMessage(FacesMessage.SEVERITY_ERROR, msg, detalles));
    }

and in my file. xhtm I have the following code:

<rich:messages globalOnly="true" layout="table" errorClass="error2" infoClass="info" warnClass="notice" >
<f:facet name="header">
<h:outputText value="Entered Data Status:"></h:outputText>
</f:facet>
<f:facet name="passedMarker">
<h:graphicImage value="/imagenes/iconos/accept.png" />
</f:facet>
<f:facet name="errorMarker">
<h:graphicImage value="/imagenes/iconos/cancel.png" />
</f:facet>
<f:facet name="infoMarker">
<h:graphicImage value="/imagenes/iconos/information.png" />
</f:facet>
</rich:messages>

and my business method of beam backen use the following call:

        //We set the success message
        addInfoMessage("ok update record");

in some pages that shows me info messages, and other pages also shows me the error messages. I can give some help to determine what might cause this behavior.

                                Thanks for your help and excuse my English
