I would like to upgrade a web app I am working on from v2.1 to v3.1 of the Javascript API (I have tried 3.2 but I am getting some very odd rending problems, so I'm settling with 3.1 for now...) One issue I have encountered is that a ComboBox populated with a store does not seem to fully function with 3.1. I was told I can fix this by replacing the ComboBox with a FIlteringSelect widget, but so far I haven't succeeded. Below is my code. I was hoping I wouldn't need to do much more than replace the ComboBox object with the FilteringSelect object, but that apparently isn't sufficient. Can somebody help me see what I am missing? Thanks, Jason

JS (old code:)

      function populateSchoolMenu(results) 
    var schoolName;
    var values = [];
    var testVals = {};

    var features = results.features;
    dojo.forEach(features, function (feature) {
        if ( (schoolLayerFlag == 0) || (schoolLayerFlag == 2) )
            schoolName = feature.attributes.Name;

        else if (schoolLayerFlag == 1)
            schoolName = feature.attributes.Site_name;


        if (!testVals[schoolName]) 
            testVals[schoolName] = true;
            values.push({ name: schoolName });

    var dataItems = {
        identifier: 'name',
        label: 'name',
        items: values
  var menuStore = new{ data: dataItems });

  dijit.byId("schoolMenu").store = menuStore;

HTML (old:)

            <select id = "schoolMenu"
            value = "Select School"
            autoComplete="true" class="comboBoxClass"

Please post the code that associates your store with your ComboBox. If you were previously using = menuStore, you need to use schoolMenu.set("store", menuStore) instead. – Derek Swingley Oct 15 '12 at 22:42
Hi, I think I added my comment below right before you did, with the same information...the code is you ask for is given above...Thanks for the feedback! – JasonBK Oct 16 '12 at 12:20

Your rendering problems with 3.2 are most likely due to ESRIs new requirement that you add a new css file to your code:

 <link rel="stylesheet" type="text/css" href="" />

thank you, that seems correct...but I am still having the problem with the FilteringSelect dropdown menu...I basically just tried replacing ComboBox with FilteringSelect in the code above (and changing the API)...Currently I get this error: "TypeError: is not a function" referencing… Line 2 – JasonBK Oct 15 '12 at 20:42
I did make some progress, by replacing this line : dijit.byId("schoolMenu").store = menuStore; with this: dijit.byId("schoolMenu").set ("store", menuStore); ..... but now I am getting other errors ("Error: Unable to complete operation.", line 34 3.2 API)..I'll keep working at it! – JasonBK Oct 15 '12 at 21:13
Is your combo box working after using set() to specify the store? – Derek Swingley Oct 16 '12 at 14:04
@Craig esri.css does not affect how Dojo dijits are rendered but does impact how the map and widgets provided by Esri (includes the map itself, info window, popup, legend, bookmarks widget, etc.) look. Since we're talking about dijit.form.ComboBox, missing esri.css is not likely to be the source of the problem. – Derek Swingley Oct 16 '12 at 14:09
the Filtering Select drop down is working more or less...I am getting some different errors as noted above; I was previously clearing the ComboBox with a .reset call, but I am now getting some errors when using the same technique with the Filtering Select. Also, I should explain my original problem a bit more clearly...the problem with the ComboBox when I upgraded the API is that the dropdown menu did not populate with the items from the store...I could type in an item hit return and get a result, but there was no populated list to select from..this now works using FilteringSelect and v3.2 – JasonBK Oct 17 '12 at 12:50
