[daisy] Help setting multivalue link field

[Derek Coffman]

Hi,

I am writing an "wizard" type extension to allow users to create and
"InstrumentDefinition" document. The document contains a multivalue link
field of "InstrumentTypes" (i.e., a list of documents of type
"InstrumentType"). In the wizard, the user is presented with a
double-listbox multivalue field and required to select at least one
type. The types are show as the name of the InstrumentType. Once the
user submits the completed form, I am trying to use getValue() of that
widget which should return an array of Strings if I understand
correctly. In order to set the multivalue link field, I need to turn
those names into an array of VariantKey...correct?

My question: what is the best way to do this in javascript? Here's one
iteration I've tried...

     var types = form.getChild("def_inst_types").getValue();

     var ids = new Array();

     for (i=1; i<types.length; i++) {
         var type_str = types[i].toString();

         searchresults = queryManager.performQuery("select id where
documentType='InstrumentType' and name='"+type_str+"'",locale.getDefault());

          rows =
searchresults.getSearchResult().getRows().getRowArray();

                var typeid = rows[0].getValueArray(0);

                var typedoc =
daisy.getRepository().getDocument(typeid,false);
                ids[i] = typedoc.getVariantKey();

      }

      var repository2 = daisy.getRepository();
      var document = repository2.createDocument(title.toString(),
"InstrumentDefinition");
            document.setField("InstrumentTypes",ids);


Am I completely off track here? When I run this, I get an error that says:

Wrapped org.outerj.daisy.repository.DocumentTypeInconsistencyException:
The value for the multivalue-field "InstrumentTypes" should be an array.
(file:/home/web/acglocal/daisy/acgwikidata/sites/cocoon/instrument/instrument.js#566)
The value for the multivalue-field "InstrumentTypes" should be an array.


Thanks for any advice you can give,
Derek
