Yes! this helps a lot!

What is the field datatype in the database table and
also what is the field base data type of the
multi-value widget?

thanks

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

  <fd:item value="bold"/>
  <fd:item value="italic"/>

</fd:multivaluefield>

BINDING
<fb:value id="style" path="style"/>

BEAN
private Object[] style;
public Object[] getStyle() {
       return style;
}
public void setStyle(Object[] style) {
       this.style = style;
}


Does this help you ?
