DGrid error - not refreshing

Since the feature table widget isn't ready yet, I'm using dgrid to display results of a query, as show in the "highlight features by geometry" example.  However it only works when I do a unique search.  If I do a search and it brings back feature 1, 2 and 3, then the grid shows.  I can do a second search, and it bring back features 3, 4 and 5, and the grid shows.  But if I redo the first search, and it gets the same result set - features 1, 2 and 3 - then it fails, and gives the error "TypeError: Cannot read propery 'element' of undefined, at _StoreMixin.js:2; which implies the error has to do with the datastore.  I've tried resetting the datastore, setting it to a blank array then back to the result set, etc; nothing works.  Does anyone have any ideas?  Code below:


function populateResultGrid(resultArray){
   document.getElementById("gridDisplay").style.display = "block";
   document.getElementById("featureCount").innerHTML = "<b>Showing attributes for " + resultArray.length + "    features</b>"
   function(OnDemandGrid, Memory, StoreAdapter, Selection){
      var dataStore = new StoreAdapter({
         objectStore: new Memory({
         idProperty: "AssetID"
   }); = resultArray;
   var grid = new(OnDemandGrid.createSubclass([]))({
      columns: getColumns()
   }, "grid")
   grid.set("collection", dataStore);
