commandButton action method not invoked in Liferay - jsf

Question

I've the 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 this 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 only thing I try to do, is to call a method which prints something to my console. The problem is that no matter what I do, the action method is never invoked. The getter method is properly called.
What am I doing wrong?

Im not sure why, but after adding this line to my liferay-portlet.xml it fixed it.
<requires-namespaced-parameters>false</requires-namespaced-parameters>
And here the 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>
