I think just using an fd:multivaluefield should work;

No. Unfortunately this does not work, as it seems that at least one instance

selection list box which is not what I want at all. I used the following:


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

    <fd:multivaluefield id="delItem">
      <fd:datatype base="string"/>

allows me to repeat a number of other widgets an unspecified amount of
