Description

Currently if you have an InputTExt with no `value` the MyFaces BeanValidator logs a WARN.

        ValueExpression valueExpression = component.getValueExpression("value");
        if (valueExpression == null)
        {
            log.warning("cannot validate component with empty value: " 
                    + component.getClientId(context));
            return;
        }

PrimeFaces always throws this when using Custom Filters that have no `value` attribute like on the Showcase here: https://www.primefaces.org/showcase/ui/data/datatable/filter.xhtml

 <f:facet name="filter">
    <p:selectOneMenu onchange="PF('customersTable').filter()" styleClass="ui-custom-filter">
         <f:selectItem itemLabel="All" itemValue="#{null}" noSelectionOption="true" />
          <f:selectItems value="#{dtFilterView.representatives}" />
    </p:selectOneMenu>
</f:facet>

I wonder if we should only LOG.WAR if in JSF Stage Development but just let it go in PRODUCTION mode
