checkbox widget with datatype vector

[Andrew]

Hi,
I have a shopping cart system which enables a user to select a number of items from their cart and delete them at the same time. This was working perfectly before I chnaged everything to widgets because I need to use ajax. What is happening now is that no matter how many items you select to delete, only one item is ever deleted at a time. Now I suspect that the problem lays with the datatype being used in fd:

    <fd:field id="delItem" required="true|false">
      <fd:datatype base="string"/> // I tried boolean and nothing was being deleted
    </fd:field>

widget definition is:

     <ft:widget id= "delItem">
        <fi:styling value="${orderitem.getID()}" type="checkbox"/>
     </ft:widget>

flow:

        delItems = bizData.delItem ;
        var items = new java.util.Vector();
       
        if (parseInt(bizData.quantity) || delItems != null) {
            try {
             
                if (delItems != null) {
               
                   if (delItems.iterator) { // A list of delItems have been selected to be deleted.
                      items.addAll(delItems);
                      deleteOrderItem2(items);
                   } else { //A single delItem has been selected to be deleted.
                      items.add(delItems);
                      deleteOrderItem2(items);
                   }
                }

Any ideas what I am missing here?

Andrew
