Hi,
        I have a Scontrol that updates a lead's LeadSource picklist value at the click of a button. The function is as follows:
        function changeLeadStatus() {
                var lead = new Sforce.Dynabean("lead");

                var list = document.getElementById("select1");

                lead.set("id", list.options[list.selectedIndex].value);

                lead.set("leadSource", "Lead Assigned");

                var saveResult = sforceClient.update([lead]);

                 for (var i=0;i<saveResult.length;i++) {

                         if (saveResult[i].success == true) {

                               alert("Yay!! I updated the lead souce successfully: " + saveResult[i].Id);

                         } else {

                          alert("Rats!  There was a problem and I think the problem is: " +                                  saveResult[i].errors[0].message);

                        }
                  }
      }

           The code runs just fine, after execution, I checked the Lead table via the appexchange plugin for eclipse, and could see the LeadSource field is indeed updated. But when I checked the lead information at saleforce.com, the leadSource field value just doesn't reflect the change.
           What is happening? Thanks for your input!
