Array undefind error in shindig-container.js

["Shoury Bharadwaj Hosahalli Venkataramana (shosahal)" <sh...@cisco.com>]

Hi,

 

   Sometimes we are hitting "arr is undefined" error when one of our
page loads. Error is occurring in shindig-container.js of
shindig-features-2.0.2.jar in the following location marked in red
colour.

 

function handleJSONResponse(obj) {

    var requiresPubSub2 = false;

    var arr = obj.data.gadgets[0].features;

    for (var i = 0; i < arr.length; i++) {

      if (arr[i] === 'pubsub-2') {

        requiresPubSub2 = true;

        break;

      }

    }

    var subClass = requiresPubSub2 ? shindig.OAAIfrGadget :
shindig.IfrGadget;

    for (var name in subClass) if (subClass.hasOwnProperty(name)) {

      gadget[name] = subClass[name];

    }

  }

};
