RequestContext.getCurrentInstance().openDialog não abre Dialog

Front-end

Pessoal, estou usando primefaces 6.0 e quando clico no botão para abrir o dialog a pagina carrega, ele acessa o metodo do actionListener no entanto não abre o Dialog, alguém pode me ajudar?

    </h:head>
     
    <h:body>
 
		<h:form>
		    <p:commandButton value="View1" icon="ui-icon-extlink" actionListener="#{EadBean.viewCars()}" ajax="false" immediate="true"/>
		</h:form>

    </h:body>          
</html>

Método:

public void viewCars() {
    System.out.println("ABRIR CFG");
    Map<String, Object> options = new HashMap<String, Object>();
    options.put("modal", true);
    options.put("draggable", true);
    options.put("resizable", false);
    options.put("contentHeight", 300);
    options.put("contentWidth", 400);
    RequestContext.getCurrentInstance().openDialog("QuestionarioRealizado.xhtml", options, null);  
    System.out.println("ABRIR CFG - fim");
}

QuestionarioRealizado.xhtml
