Thanks but still not working i made them private now. I'm totally lost with action script and object mapping. Do i need to use action script for the value objects i have, if that so is there any easy way to write action scripts same as the java objects.
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"; initialize="initApp()" xmlns:i2view="view" pageTitle="Test Application"> <mx:Script> import src.com.flex.form.*; var users: Array; var upForm: UserProfileForm; var closerResultsForm: CloserResultsForm; var userList: Array; var resultList: Array; function initApp() { ro.getResults(); // returns CloserResultsForm as a collection } function getUserList_result(event) { userList=event.result; } function getResultList_result(event) { resultList=event.result; } </mx:Script> <mx:RemoteObject id="ro" source="com.chl.dataaccess.CloserDataAccess"> <mx:method name="getResults" result="getResultList_result (event)"/> </mx:RemoteObject> <mx:DataGrid id="dg" dataProvider="{resultList}" width="838" editable="true" showHeaders="true"> <mx:columns> <mx:Array> <mx:DataGridColumn columnName="firstname" headerText="Firstname"/> <mx:DataGridColumn columnName="lastname" headerText="Lastname"/> </mx:Array> </mx:columns> </mx:DataGrid> ** This is the situation i'm in now, we're going to develop new apps using RIA technology, we don't have time to learn action scripts or any other vedor specific scripts. so i'm trying to convince that flex is the best solution, but it looks like flex dev is not rapid as what i saw from demo, still lots of manual coding has to be done. May be i'm not understanding fully about flex. So can you guys tell me whether i should use flex or coldfushion or ajax with struts as i did before.
