Returning new address internalid from restlet

Hi all,

At my wits end here trying to accomplish something:

I have a restlet that accepts details to create a new address line in an existing customers addressbook. It works, saves and all - however I need to return the internalId of the freshly created addressbook entry, but I can't seem to figure out how to do it. here is the stripped down code:

   function editCustomerAddress( data ) {      record = nlapiLoadRecord('customer', data.entityId );   record.selectNewLineItem('addressbook');             for( addressfield in data["address"] ) {        value = data["address"][addressfield];    record.setCurrentLineItemValue( 'addressbook', addressfield, value, true);     }    //WHy this doesn't return the id is confuzzling me.   var id = record.commitLineItem('addressbook');   nlapiSubmitRecord( record );      return {id: wtf?};  }
