Setter never get called in selectManyCheckbox!!

Question

Hello
I posted a topic about selectManyCheckbox / selectItems , but I didnt receive any reply , so
I reviewed earlier threads talking about the same problem:
* setter method NOT CALLED* for selectManyCheckbox :
http://forum.java.sun.com/thread.jsp?forum=427&thread=398097
" ....My page is rendered with all of the correct checkboxes I require.
One for each object in the problemOptions list.
Once I check the boxes I want and submit the form,
I am losing my choices when I come back to the same page.
I noticed that I never see my setter being called.... "
http://forum.java.sun.com/thread.jsp?forum=427&thread=401926
"..if one ore more items are selected, ..... ,
after it called the getter 3 times and the setter not at all.
there is no error message and no stack in any of the logs...."
this is sample of my JSP/backing bean :
JSP :
  <h:selectManyCheckbox  id="foodType" value="#{productBean.foodType}">
        <f:selectItems value="#{productBean.foodTypes}" />
  </h:selectManyCheckbox>
Backing bean class ProductBean :
  private ArrayList foodType = new ArrayList();
  private ArrayList foodTypes = new ArrayList();
public ProductBean()  {
    foodTypes.add(new SelectItem("Sweet","Dweet label","Sweets"));
    foodTypes.add(new SelectItem("desert","Desert label","Deserts"));     
    foodTypes.add(new SelectItem("seeFood","SeeFood label","SeeFoods"));   
  public Object[] getFoodType() {
      try {
        return foodType.toArray(); }
      catch (Exception ex) { return null;  }
  public void setFoodType(Object[] newFoodType) {
    // NEVER GET CALLED !!!
    int len=0;
    if (null == newFoodType || ( len = newFoodType.length)==0 ) {    return; }
    foodType.clear();
    foodType = new ArrayList(len);
    for ( int i=0;i<len;i++) {   foodType.add(newFoodType); }
public ArrayList getFoodTypes() {
return this.foodTypes;
public void setFoodTypes(ArrayList foodTypes) {
this.foodTypes = foodTypes;
what am I doing wrong ? , I'm really stuck , what may be the reason for JSF not to call setter for setFoodType??
I saw a reply for Adam.winner stating that it is not suitable to use Object[] type as setter argument ,
and to use String[] instead, but this was in EA4 .
is this still applicable for JSF 1.0 FR ?
I appreciate any help

The data type of the SelectItem itemValue properties must be the same basic type (primitive or the corresponding boxed type) as the data type of the UISelectMany/UISelectOne value.
In this example, the SelectItem itemValue properties are of type String, but the UISelectMany value is of type Object. Change it to String, and it should work.
