If a FilteringSelect dijit contains a comma in the value clause, things don't work as expected. Consider the following code:
<option value="value one">one</option>
<option value="comma, test">two</option>
<option value="value three">three</option>
</select>
You'd expect that the option with the label "two" would be selected. In Firefox 3, nothing gets selected, but Firebug reports no errors. In IE 6, an error is thrown: '0.oper' is null or not an object.
