Identify Service pass back object

Hi,

I'm trying to start several Identify tasks simultaneously, the results of each must be associated with a predetermined object. The issue is how to know what object to assign which response to?

In silverlight I used the 'userToken' object which did a round trip and was passed back with the results. How is this achieved in JavaScript against the REST API?

Assuming there is no pass back facility exists I looked at using the deferred functionailty of DOJO:

LOOP N = 1 to Query.count
   var OBJ = Query(N); //OBJ to be attached to results is known here
   idfyParams.geometry = OBJ.geometry
   var idfyTask = new esri.tasks.IdentifyTask(url);
   idfyTask.execute(idfyParams).then(function(results){
      //Use results and OBJ or QUERY(N)
   });
END LOOP

So will OBJ, N or QUERY(N) be correct when identify resolves each time? Do I need to hitch the OBJ? I wonder if OBJ will just be the last value it was set to i.e. QUERY(QUERY.count).

Thanks,

Matthew

Take a look at this post over in GIS.StackExchange that uses a DeferredList to process multiple Identify tasks
