Description

This issue effects only spring-boot.

<tc:in label="Name" value="#{helloSpring.name}" required="true">
  <f:facet name="after">
    <tc:button label="Submit" defaultCommand="true" action="#{helloSpring.sayHello}"/>
  </f:facet>
</tc:in>
<tc:file/>

public String sayHello() {
  LOG.info("Action was called, name is '{}'", name);
  return "/result.xhtml";
}

Solution:
put this code in the Application.java

  @Bean
  public ServletContextInitializer multipartServletContextInitializer(MultipartConfigElement multipartConfigElement) {
    return servletContext -> {
      ServletRegistration servletRegistration = servletContext.getServletRegistration(FACES_SERVLET_NAME);
      if (servletRegistration instanceof ServletRegistration.Dynamic) {
        ((ServletRegistration.Dynamic) servletRegistration).setMultipartConfig(multipartConfigElement);
      }
    };
  }

The FacesServlet needs to support <multipart-config> usually set in the web.xml.

(its now as example in the sping-boot demo)
