The problem is that you are not sending any data from Flex. You have
remoteObj.userData.send()
on creationComplete but you do not have any parameters for that function so no
data is sent. The CF code requires the username and password parameters but
does not get them.
You obviously want to send this data with your call but you can't if you invoke
the remoteObject call on creationComplete.
So, the first thing to do is remove the invocation from creationComplete. Next,
you should add a button to your form and create a function to run on click of
the button.
<mx:Button label="Login" click="doLogin()"/>
private function doLogin():void
{
remoteObj.userData.send();
}
<mx:RemoteObject id="remoteObj" destination="ColdFusion"
source="example3.cfc.log">
<mx:method name="userData" result="concernOriginalReceived(event)"
fault="Alert.show(event.fault.faultString,'Error');">
<username>{username}</username>
<password>{password}</password>
</mx:method>
</mx:RemoteObject>
This is only one way of doing it. There are others.
I would recommend using Charles (http://www.charlesproxy.com) to debug these
kinds of errors. You would see very quickly that Flex did not send any data.
