The Employee class must implement Serializable,
that's missing, try that and see if it fixes your
problem.

Subject: [flexcoders] Error: Cannot invoke method
triffling thing is that there is not problem with the way code is
written and i cannot find any configuration issues. Moreover i do not
know how to get to the exact error.
It is a simple code in which i am using a VO there's a corressponding
AS file which registers with the java VO. i have configured the
whitelist properly. i tried configuring NetConnectionDebugger the way
its given in Macromedia's site, but even that is not getting configured.
I cannot see anythin in the panel.
I have been into this weird problem for sometime now. I replicated the
code and tried to run it by building a seperate war, the same example
got executed. i want to know how to debug these kind of problems. Is
there any way to know the exact error.
because "Error: Cannot invoke method 'methodName'" doesn't help me in
any way.
Kindly respond soon.
i'm putting the code blocks here:
1. SimpleForm.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
initialize="initApp()">
<mx:Script>
import mx.managers.CursorManager;
import mx.core.UIObject;
import sample.data.*;
var emp: Employee;
var inputBlocker;
function initApp() {
emp=new Employee();
}
function update() {
setBlockingCursor();
//applyChanges();
emp.firstName=firstName.text;
emp.lastName=lastName.text;
srv.addEmployee(emp);
}
function addEmp_result(event) {
setBlockingCursor();
}
function faultHandler(event) {
removeBlockingCursor();
mx.controls.Alert.show(event.fault.faultstring, 'Error');
}
function applyChanges(){
emp.firstName=firstName.text;
emp.lastName=lastName.text;
}
function setBlockingCursor() {
inputBlocker = popupWindow(UIObject);
CursorManager.setBusyCursor();
}
// Remove our blocking popup
function removeBlockingCursor() {
inputBlocker.deletePopUp();
CursorManager.removeBusyCursor();
}
</mx:Script>
<mx:RemoteObject id="srv" source="sample.data.SimpleService">
<mx:method name="addEmployee" result="addEmp_result(event)"
fault="faultHandler(event)"/>
