SUPStorage api in SUP 2.1 to store array or structure

Question

Hi,
I am using below code to store key value pair using SUP api for offline storage in workflow apps:
SUPStorage.prototype.setItem(j, airlineId);
Example: var j = 1;
              var airlineid = "lufthansa";
  This works fine, but I want to store an array or at least a structure (single row) which has multiple items. How can we do that?
I tried passing MBO value data directly, but it gives exception while I try to read:
var mvc = getCurrentMessageValueCollection();
      var fData = mvc.getData("flightmbo");
      var values = fData.getValue();
     var i = 1;
     SUPStorage.prototype.setItem(i, values);
   This does not give any exception, but when I try to read by using code:
var  i = 1;
    airlineKey =  SUPStorage.prototype.key(i);
    values =  SUPStorage.prototype.getItem(airlineKey);
var j = 0;
   var theItems = values[j];
This gives exception saying "Type Error: Result of expression 'values' [null] is not an object".
Any workarounds to store a structure/array with the same key (such as airline id, text, time, availability).
Thanks,
Rohit

Have you tried converting the array/structure to a string using JSON (or some similar technique) and storing it that way?
