Also, I advise against using lastResult. This property is intended for use in binding expressions, and you cannot depend on its value when you access it in AS code (though it usually works). Instead, use event.result:
... var xmlResult:XML = XML(event.result); trace(xmlResult.toXMLString()); //So you know how to write the xmllist expression var xlJobs:XMLList = xmlResult.job; trace(xlJobs.length()); //is this number what you expect? datagrid.dataProvider = xlJobs; Note that if you ever decide to use binding instead of directly assigning the dataProvider, do not use XMLList because it is not bindable. Wrapt that in an XMLListCollection instead. Tracy ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Clinton D.
