Is MyFaces 4.0.2 h:commandScript still supposed to function?

I created a minimalistic test to see if commandScript still passes the arguments to the bean but it does not seem to do so anymore. Am I reading them from the wrong place?

When I press the button in the example I created the backend is called but the requestParameterMap does not contain my submitted value.

The button calls the javascript function and that function calls the commandScript. Somhow I thought this was more clear :)

See https://github.com/MilovdZee/myfaces-minimal-test for the example. And down here the relevant snippets.

@Log4j2
@Named
@SessionScoped
public class CommandScriptBean implements Serializable {
    public String getButtonName() {
        log.info("getButtonName");

        return "button";
    }

    public void commandScript() {
        log.info("CommandScriptBean");

        FacesContext fc = FacesContext.getCurrentInstance();
        ExternalContext ec = fc.getExternalContext();
        Map<String, String> requestParameterMap = ec.getRequestParameterMap();
        log.info("Passed value: 'test'='{}'", requestParameterMap.get("test"));
    }
}

and

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="jakarta.faces.html"
>
<h:head>
    <title>Minimal test</title>
</h:head>
<h:body>
    <h:form id="form1">
        <h:commandScript id="jsFunction"
                         name="jsFunction"
                         actionListener="#{commandScriptBean.commandScript}"
        />
        <script>
            function testFunction() {
                console.log("testFunction");
                jsFunction({"test": "value"});
            }
        </script>
        This is a form<br/>
        <h:commandButton id="button" onclick="testFunction(); return false;" value="#{commandScriptBean.buttonName}"/>
    </h:form>
</h:body>
</html>

Hi I am the implementer of the myfaces ajax scripts, this could be related to a problem I am investigating atm https://issues.apache.org/jira/browse/MYFACES-4710 It looks closely like it, the parameters get lost along the way. I am looking into the issue, please also check the bug report for updates on this, it should be fixed the next few days!
