new Navigation object throwing error

whenever I'm instantiating a new Navigation object I'm getting an error: 
Cannot read property 'query' of null


upon inspection of the objects everything looks correct but it fails every time.  Has anyone else experienced this?

I'm using ArcGIS js version 3.6

Here's my instantiation call: 
require(['esri/map', 'esri/layers/ArcGISTiledMapServiceLayer', 'esri/layers/ArcGISDynamicMapServiceLayer', 'esri/symbols/PictureMarkerSymbol', 'esri/renderers/SimpleRenderer', 'esri/toolbars/navigation', 'esri/dijit/Scalebar'], function(Map, ArcGISTiledMapServiceLayer, Navigation, Scalebar) {       nsmap.map = new Map(mapID, {         basemap: 'gray', //valid options: "streets" , "satellite" , "hybrid", "topo", "gray", "osm"         center: [-84.858, 37.388],         zoom: initLevel,         lods: lod,         slider: false       });        nsmap.nav = new Navigation(nsmap.map);      });


Thanks

Correct Answer
Your require classes does not match with the function arguments order......
require([  "esri/toolbars/Navigation", "dijit/registry", ...  ], function( Navigation, registry, ... ) {


Order must be followed when creating a function with require. Your navigation object is taking reference of 'esri/layers/ArcGISDynamicMapServiceLayer'
