jsf - commandButton action method not invoked in Liferay -

i've below portlet view.xhtml:

 <?xml version="1.0"?>     <f:view xmlns="http://www.w3.org/1999/xhtml"         xmlns:c="http://java.sun.com/jsp/jstl/core"         xmlns:f="http://java.sun.com/jsf/core"         xmlns:h="http://java.sun.com/jsf/html"         xmlns:ui="http://java.sun.com/jsf/facelets"         xmlns:p="http://primefaces.org/ui">              <h:body>                  <h:form>                     <h:commandbutton value="testbutton" action="#{navigationviewbean.submit}" />                     <h:outputtext value="testgetter: #{navigationviewbean.testfield}" />                 </h:form>             </h:body>     </f:view> 

and managed bean:

import javax.faces.bean.managedbean; import javax.faces.bean.requestscoped;  @managedbean(name = "navigationviewbean") @requestscoped public class navigationviewbean {     private string testfield;     public boolean lol = false;      public void submit() {         system.out.print("test button invoked");     }      public string gettestfield() {         system.out.print("test getter invokedx");         return testfield;     }      public void settestfield(string testfield) {         this.testfield = testfield;     }  } 

the thing try do, call method prints console. problem no matter do, action method never invoked. getter method called.

what doing wrong?

im not sure why, after adding line liferay-portlet.xml fixed it.

<requires-namespaced-parameters>false</requires-namespaced-parameters> 

and here whole block:

<portlet>         <portlet-name>test1</portlet-name>         <icon>/icon.png</icon>         <requires-namespaced-parameters>false</requires-namespaced-parameters>         <header-portlet-css>/css/main.css</header-portlet-css> </portlet>
