RE: [flexcoders] Error: Cannot invoke method
The Employee class must implement Serializable,
that's missing, try that and see if it fixes your
problem.

I get this error when trying to use Remote Object via AMF. The
mosttriffling thing is that there is not problem with the way code
iswritten and i cannot find any configuration issues. Moreover i do
notknow how to get to the exact error. It is a simple code in which i am
using a VO there's a corresspondingAS file which registers with the java VO.
i have configured thewhitelist properly. i tried configuring
NetConnectionDebugger the wayits 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 thecode and
tried to run it by building a seperate war, the same examplegot executed. i
want to know how to debug these kind of problems. Isthere any way to know
the exact error. because "Error: Cannot invoke method
'methodName'" doesn't help me inany way.Kindly respond
soon.i'm putting the code blocks here:1.

[flexcoders] Error: Cannot invoke method
Guys
I don't know what else to do with this error. The problem is that flex
do not recognize the mapping between a VO Client Class and the Server
VO. In fact I get the following message using the Alert PopUp Window:
"The expected argument types are (vo.VOEmpleado) but the supplied
types were (flashgateway.io.ASObject) and converted to (null)"
Let me show you my code:
At CLIENT Side.
class vo.VOEmployee {
public var id:Number;
public var nombre:String;
public var cargo:String;
public var superior:Number;
public var ingreso:Date;
public var sueldo:Number;
public var comision:Number;
public var iddepto:Number;
public static var regClass =
Object.registerClass("vo.VOEmpleado",vo.VOEmployee);
public function VOEmployee() {
}
}
At SERVER Side..
package vo;
import java.io.Serializable;
import java.util.Date;
/**
* @author mwt00222
*
* TODO To change the template for this generated type comment go to
* Window - Preferences - Java - Code Style - Code Templates
*/
public class VOEmpleado implements Serializable{
public int id;
public String nombre;
public String cargo;
public double superior;
public Date ingreso;
public double sueldo;
public double comision;
public int iddepto;
public VOEmpleado() {
}
/* (non-Javadoc)
* @see java.lang.Object#toString()
*/
public String toString() {
return this.id + "-" + this.nombre + "-" + this.cargo;
}
}
The METHOD at the Remote Obejct
public int createEmployee(VOEmpleado vo) {
System.out.println("createEmployee:");
return 0;
}
Any IDEA ??

RE: [flexcoders] Error: Cannot invoke method when using a VO
Does the Java version of Group have a public no args constructor? -Original Message- From: cazzaran [mailto:[EMAIL PROTECTED] Sent: Monday, March 28, 2005 3:50 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Error: Cannot invoke method when using a VO I have a delegate class on my server called GroupDelegate, and it has a method addGroup(Group group). When I try and call this method on my remote object, I get the error: Error: Cannot invoke method addGroup However, if I switch my method's signature to addGroup(String groupName), the method executes, and the group is added to the DB. Group is just a POJO, and obviously the second method wont work because there is a lot more information than just the groupName that needs to be recorded... Interestingly, when I do a getGroups I get back an array of the correct objects, and in my client side model of my Group class I have correctly done the Object.registerClass. The only time I seem to have an issue is when I pass it BACK to my server as a Group. Any ideas? -Josh Yahoo! Groups Links Yahoo!
