BasemapGallery with DynamicMapService

[Anonymous User]

I am using a dynamic map service as my operational layer which is in a UTM (meters) projection. I am trying to implement the BasemapGallery. A couple issues:

1.) The initial basemap (topo) does not appear when loading the application.

2.) When choosing a difference basemap, the operational layer disappears and the basemap does not appear...blank screen. Code snippet is below.

Any ideas?

Thanks in advance,

map = new esri.Map("map",{
     infoWindow:popup,
     basemap: "topo",
     logo: false,
     extent: new esri.geometry.Extent({xmin:705766,ymin:4341305,xmax:706059,ymax:4341504,spatialReference:{wkid:26914}}),
     sliderStyle:"small"
        });

var basemapGallery = new esri.dijit.BasemapGallery({
          showArcGISBasemaps: true,
          map: map
        }, "basemapGallery");
        basemapGallery.startup();       
        dojo.connect(basemapGallery, "onError", function(msg) {console.log(msg)});


layer = new esri.layers.ArcGISDynamicMapServiceLayer("http://myDirectory/rest/services/myService/MapServer", {"imageParameters":imageParameters, id:"dynamicLayer"});

map.addLayer(layer);

I think this may be the problem, I read this from esri sample:

You can add additional basemaps to the gallery, however all basemaps added to the BasemapGallery need to be in the same projection. If you are displaying basemaps from ArcGIS.com by setting showArcGISBasemaps = true then the additional basemaps must be in the Web Mercator projection.

So try to change the projection of your map service to "Web Mercator".
