Have you managed to turn on debugging for remote-object in /WEB-INF/flex/flex-config.xml and looked at the trace of the AMF error in the NetConnection Debugger? There may be more information on the fault object in the rootcause property.
If you have access to the server locally, you can also try turning on Debug level logging for the AMF Gateway in /WEB-INF/flex/gateway-config.xml and checking your Flex logs (or possibly just watching the console output if you manually launch JRun and have console logging enabled for Flex). This will show you what data type was being deserialized for your input parameter and it will also let you see the raw response going back with information similar to that shown in the NetConnection Debugger (though the server side is more accurate as the NCD is an old Flash Remoting tool that has a few issues - mainly that it doesn't show objects typed with Object.registerClass). -----Original Message----- From: cazzaran [mailto:[EMAIL PROTECTED] Sent: Monday, March 28, 2005 4:58 PM To: [email protected] Subject: [flexcoders] Re: Error: Cannot invoke method when using a VO Peter, Here's my whitelist: <whitelist> <unnamed> <source>*</source> </unnamed> <named> <object name="userDelegate"> <source>businessdelegates.UserDelegate</source> <type>stateful-class</type> <allow-unnamed-access>false</allow-unnamed-access> </object> <object name="groupDelegate"> <source>businessdelegates.GroupDelegate</source> <type>stateful-class</type> <allow-unnamed-access>false</allow-unnamed-access> </object> </named> </whitelist> -Josh --- In [email protected], "Peter Farland" <[EMAIL PROTECTED]> wrote: > Ah, what does the unnamed whitelist in the remote-object section look > like?
