TypeError: this.spatialReference is undefined

MatthewBorr — Wed, 28 May 2014 16:36:44 GMT

I am calling two services, but getting this error in firebug: "TypeError: this.spatialReference is undefined"

 var it = new InfoTemplate();
    it.setTitle("Low Income Housing Information");
    it.setContent("<b>Score:</b>${Score}<br/>" +
                            "<b>Name: </b>${Name}<br/>" +
        "<br><b>Address:</b> ${Address}<br>"  );
                         

  
 var a = new FeatureLayer("http://gis-server.cc.wmich.edu/harcgis/rest/services/hdream/house/MapServer/0",
  { mode: FeatureLayer.MODE_SNAPSHOT,
 infoTemplate: it,
 } );
    
 var b = new FeatureLayer("http://gis-server.cc.wmich.edu/harcgis/rest/services/hdream/kcountyborder/MapServer/1" );
 
  
  

    map.addLayer(a)
   map.addLayer(b)

Puzzled as to what this error is, and how to fix it?

Also "Unexpected value NaN parsing x attribute." Are these errors related. Is there a problem in the service(s) itself or the code?

I have seen this error too. Frequently is was from trying to use a map right away, instead of waiting for the onload event to fire
