onMapLoaded handler in Router. I do this so that we wait until the map is ready, and THEN dispatch events telling is how to re-hydrate it's state

RouterOnMapLoadedSnipped.js

onMapLoaded:function(){
  //ok, now that we have a map we can link up some events
  Viewer.vent.on('FireLayer:ConfigChanged',this.setYear);
  //and if we have values passed in on the url, raise events
  if(this.urlValues){
      Viewer.vent.trigger('FireLayer:ConfigChanged', this.urlValues.yearData);
      Viewer.vent.trigger('Map:ShowPerimeters',this.urlValues.yearData);
      Viewer.vent.trigger('Navbar:ChangeItemName',this.urlValues.yearData.model.name);
      Viewer.vent.trigger('Map:CenterAtLatLongAndZoom', {
          x:this.urlValues.x, 
          y:this.urlValues.y, 
          l:this.urlValues.l
      });
  }else{
      //do the defaults - this is essentially what starts the app
      //with the active fires
      Viewer.vent.trigger('FireLayer:ConfigChanged', this.active);
      Viewer.vent.trigger('Map:ShowPerimeters',this.active);
      Viewer.vent.trigger('Navbar:ChangeItemName',this.active.model.name);
  }
}
