Description

The error occures in the tobago.js in the overlay.overlay("destroy") call. In the given case the overlay variable is not an overlay.

      case Tobago.Updater.CODE_NOT_MODIFIED:
        if (typeof this.afterDoUpdateNotModified == 'function') {
          this.afterDoUpdateNotModified();
        }
        overlay.overlay("destroy");
        break;

Resolution: checking the existence of an overlay with

overlay.data("tobagoOverlay") != null
