David,

  See if this helps:

...
        classDef.breakCount = 5;
        classDef.classificationMethod = "quantile";
        classDef.type = "classBreaksDef";
        if(this.selectNorm.get('value')){
          classDef.normalizationType = "field"
          classDef.normalizationField = this.selectNorm.get('value');
        }
...

David,

   Give these changes a try. Basically you where refreshing and trying to recreate the legend before the new renderer was applied.

I can't figure out why the legend will not refresh until I change the view or navigate.

startup: function() {
   this.own(on(this.selectField, "change", lang.hitch(this, this.onFieldChange, this.legendRefresh)));

.......

legendRefresh: function(evt){
   this.legend.refresh();
},

I tried to add this.legend.refresh(); to the end of onFieldChange, but it doesn't make sense having to call legend.refresh() right after legend.startup() runs within the createLegend function.

David,

   Have you tried a layer refresh?

I have, and the layer does refresh on the map:

this.map.getLayer("tracts").refresh();

But the legend does not refresh.

David,

  I think you attached the wrong Widget.js. That one you attached is for Google Earth or something.

Very helpful.  It won't let me mark this as the answer, maybe because I branched the discussion from one of your posts?  Anyway, if you ever get to Chicago, I need to buy you a drink!
