Hi Trent,

Thank you report.
Recently there was an issue submitted for similar situation when trigger of postback was not a "submit" button which triggers form onsubmit event, but a control which uses __doPostBack(...).
Javascript in Ifragistics.Web.UI was adjusted to support that scenario. If your application also had triggers with __doPostBack, then I expect that coming service releases will support original application without "work around" which you applied.
