Query vCloud vApp by name from vCO

Hello,

I have been using the following discussion as a reference to query a vCloud vApp object from vCO using a name string.

http://communities.vmware.com/thread/391401

My code looks like:

var queryService = vcloudServer.getQueryService()
var expression = new VclExpression(VclQueryVAppField.NAME, vAppName, VclExpressionType.EQUALS);
var filter = new VclFilter(expression);
var params = new VclQueryParams();
params.setFilter(filter);
var vApp = new Array();
var resultSet = queryService.queryRecords(VclQueryRecordType.VAPP, params);
while (resultSet != null)  {
    var records = resultSet.getRecords(new VclQueryResultVAppRecord());
    System.log(records.length + " records found");
    for each (var record in records) {
        if (record.vdc == vdc.getReference().href) {
            var vAppRef = new VclReference();
            vAppRef.href = record.href;
            vAppRef.name = record.name;
            vAppRef.type = record.type;
            vAppRef.push(vdc.getHost().getEntityByReference(VclEntityType.VAPP, vAppRef));
            }
        }
    resultSet = resultSet.getNextPage();
}
System.log("vApp(s) found:"+vApp.length)

Where vcloudServer is of the type vCloud:Host and vAppName is the name of the vApp I am looking for (string type).

The workflow runs but it never finds anything.

Any clue what is the problem here?

(vCO 5.1, vCloud director 5.1)

Thanks,

Juan.
