Answer 1

Setting command parameters by setParam(key,value) can be done like that:

In your menu generating bean:

DefaultMenuItem item = new DefaultMenuItem("display list");
item.setId("listMenuItem");
item.setCommand("#{myBean.displayList}");
item.setParam("listId", 1l);

---

In your managed bean containing the action:

public String displayList(ActionEvent event) {
    MenuItem menuItem = ((MenuActionEvent) event).getMenuItem();
    Long id = Long.parseLong(menuItem.getParams().get("listId").get(0));
    findListBy(id);
}

Reading parameters seems to be a bit complicated. But ActionListeners aren't supported by Primefaces 4 MenuItems (because they aren't derived from UICommand any more) so params seem to be new new way.

Answer 2

Optimus here, use setParam(key,value). You need to update to trunk code though for this.
