JSF does not call action in managed bean

[Stefan Meier]

Hi *,

I am trying to migrate a small web application to JSF. The app will run on WAS 6.1, I decided to use JSF RI 1.1.01.

I have a main JSF view from which the user can navigate to other pages. The problem is that the main JSF does not call any action on the associated managed bean as soon as I add an

  <h:selectOneMenu binding="#{Main_Backing.advertSelectOneMenu}"/>

element. I also tried to use value-binding

  <h:selectOneMenu value="#{Main_Backing.advert}">
    <f:selectItems value="#{Main_Backing.advertList}" />
  </h:selectOneMenu>

but without success. As soon as this selectOneMenu resides on the form in the view, nothing (except of a roundtrip) happens... I inserted <h:messages/> but did not get any validation errors. No output to the console or runtime errors as well...

Here are some fragments:
main.jsf

<h:form>
  <h:messages />		
  <h:commandButton image="../../images/log_anzeigen.gif" value="#{res[\'login.main.logView\']}" action="#{Main_Backing.logView}" />
  <h:commandButton image="../../images/download.gif" value="#{res[\'login.main.logDownload\']}" action="#{Main_Backing.logDownload}" />
  <h:selectOneMenu binding="#{Main_Backing.advertSelectOneMenu}"/>
  <h:commandButton image="../../images/content_bearbeiten.gif" value="#{res[\'login.main.contentEdit\']}" action="#{Main_Backing.contentEdit}" />
 <h:commandButton image="../../images/abmelden.gif" value="#{res[\'login.main.logoff\']}" action="#{Login_Backing.logout}" />
</h:form>

Main_Backing (Main.java)

    private HtmlSelectOneMenu advertSelectOneMenu;

    public HtmlSelectOneMenu getAdvertSelectOneMenu() {
        if (advertSelectOneMenu == null)
            advertSelectOneMenu = new HtmlSelectOneMenu();
        
        final Collection list = new ArrayList();

            list.add(new SelectItem("1", "first entry"));
            list.add(new SelectItem("2", "second entry"));
                
            final UISelectItems items = new UISelectItems();
            items.setValue(list);
            advertSelectOneMenu.getChildren().add(items);
            
        return advertSelectOneMenu;
        
    }

    public String logDownload() {
        return "success";
    }

    public String logView() {
        return "success";
    }
    
    public void setAdvertSelectOneMenu(HtmlSelectOneMenu advertSelectOneMenu) {
        this.advertSelectOneMenu = advertSelectOneMenu;
    }

Thanks a lot for your help!
