Was debugging some code that was broken due to jquery 1.6 update, and found this call for Jquery dropdown.val
$("#dropDownSelect option[text=" + myText +"]").attr("selected","selected") ;
Not working anymore but a simple fix of changing it to
$("#dropDownSelect option[text=" + myText +"]").prop("selected",true) ;
This does the trick, for more on prop take a look at the api of jquery http://api.jquery.com/prop/
