title: How do I set the default value for a Dojo FilteringSelect using a JsonRest Store
body: <p>I've successfully setup my FilteringSelect to query my server for items dynamically using the JsonRest store. My problem is when I try to initially set the dropdown with specific value.</p>
  
  <pre>
  &ltdiv id="ddThings"&gt&lt/div&gt
  &ltscript type="text/javascript"&gt
  
      dojo.ready(function () {
  
              var storeThings = new dojo.store.JsonRest({ target: "/Things/" });
              var ddThings = new dijit.form.FilteringSelect({
                  name: "thingId",
                  searchAttr: "name",
                  autoComplete: true,
                  value: "5",
                  missingMessage: "This is required",
                  placeHolder: "Select a Thing",
                  store: dojo.data.ObjectStore({ objectStore: storeThings })
          }, "ddThings");
  
          ddThings.startup();
  
          //ddThings.set("value", "5");
  
      });
  </pre>
  
  <p>When I set value to "5" or using ddThings.set I can see the filteringselect querying my server and passing in an "id" value. I return a collection of things with the single item in it. I expected it to populated the filteringselect with the item I returned. But, instead nothing happens.</p>
  
  <p>The returned JSON looks like this</p>
  
  <pre>
  [
     {
        "id":"5",
        "name":"Example"
     }
  ]
  </pre>
  
  <p>One interesting note is that if I set "displayedValue" to "Example" (whatever the name is) then I can see it hit the server, find a match and return it and it actually populates the dropdown with the matching item. I want this behavior but by using the value/id of the item, not the display/name of it.</p>
