Re: multi-value widget question

[Jorg Heymans]

okay, i have another case that is similar. selectedGroups is a 
collections of Group objects, each group has an "id" and "name". Upon 
loading i grab them from the db, upon saving i reconstruct a collection 
with only the id's (formValue[i]) of the groups.

BINDING
  <fb:javascript id="targetgroups" path="selectedGroups" direction="load">
    <fb:load-form>
     var collection = jxpathPointer.getNode();
     widget.setSelectionList(collection, "id", "name");
    </fb:load-form>
  </fb:javascript>
  <fb:javascript id="targetgroups" path="." direction="save">
    <fb:save-form>
      var formValue = widget.getValue();
      var collection = new java.util.ArrayList();
      for(var i=0; i&lt;formValue.length; i++) {
        collection.add(new java.lang.Integer(formValue[i]));
      }
      var bean = jxpathPointer.getNode();
      bean.setSelectedGroups(collection);
    </fb:save-form>
  </fb:javascript>
Hope this helps :-)

Thank you Jorg, very kind of you to reply.  This is a
good start.
My case differs in that my multiselect list has a
"key-value" setup i.e I have things like 

value=1 label=Worker
value=2 label=Manager
value=3 label=Admin
and so, when I save, I want to save the values and not
the labels.
ie my widget base data type is "integer"
also, I am persisting it to a database, so the set
method has to finally get its value into a db.
thx
