How to get join results using backbeam Android SDK? -

-

i using backbeam back-end , implementing backbeam's android sdk.

i want performing joins results. using below code documentation getting join results: 

backbeam.select("place") .setquery("join last 10 events") .fetch(100, 0, new fetchcallback() {    @override   public void success(list<backbeamobject> objects,     int totalcount, boolean fromcache) {     // pick place (in real code check objects.size() first)     backbeamobject place = objects.get(0);     joinresult join = place.getjoinresult("events");      list<backbeamobject> events = join.getresults();     int count = join.getcount();   } });

i'm getting exact count of join relationship using getcount(). issue is, join result's list size returned '0' in getresults().
