Here's one quick example:

package org.ahs.jsf.controls;

import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.faces.component.UIComponent;
import javax.faces.component.UIInput;
import javax.faces.component.UIViewRoot;
import javax.faces.context.FacesContext;

public class ControlMapBean {

   public String save() {
     UIViewRoot viewRoot =
       FacesContext.getCurrentInstance().getViewRoot();
     Map<String, Object> controlMap =
       new HashMap<String, Object>();

     analyzeComponent(viewRoot, controlMap);

     // do stuff with loaded control map

     return null;
   }

   private void analyzeComponent(UIComponent uic,
       Map<String, Object> controlMap) {
     if (uic instanceof UIInput) {
       controlMap.put(uic.getId(),
         ((UIInput)uic).getValue());
     }

     if (uic.getChildCount() > 0) {
       List<UIComponent> children = uic.getChildren();
       for (UIComponent child : children) {
         analyzeComponent(child, controlMap);
       }
     }
   }

}

This is barebones. Once you have the control map it's up to you to
interpret the map values, but presumably that's where your logic comes
in, because at a minimum you need to know what the ID's correspond to.
In general they will be single values or arrays
(object.getClass().isArray() will help you here).
