Hi
Trying to build out the Ray Ryan best practices sample in GWT 2.0 ,
having trouble with the action(command)/response objects, containing
array list instances. This is Ray's sample........
package com.play.client;
import java.util.ArrayList;
public class GetDetails implements Action<GetDetailsResponse> {
private final ArrayList<ContactDetailId> ids;
public GetDetails(ArrayList<ContactDetailId> ids){
this.ids = ids;
}
public ArrayList<ContactDetailId> getIds(){
return ids;
}
}
This is my latest try..........
public class GetDetailsAction implements Action<GetDetailsResponse>,
IsSerializable {
private ArrayList<ContactDetailId> ids;
public GetDetailsAction(){
}
public GetDetailsAction(ArrayList<ContactDetailId> ids){
this.ids = ids;
}
public ArrayList<ContactDetailId> getIds(){
return ids;
}
}
public class ContactDetailId implements IsSerializable{
private String id;
public ContactDetailId(String id){
this.id = id;
}
public String getId(){
return id;
}
}
To Explain my changes, I have:-
* Changed the name because I felt like it
* Added a no-parameter constructor because "[ERROR] [testgwt]
com.play.client.Action<T> has no available instantiable subtypes.
(reached via com.play.client.Action<T>)"
* Removed the final modifier from the id's intance member because
'[WARN] [testgwt] Field 'private final
java.util.ArrayList<com.play.client.ContactDetailId> ids' will not be
serialized because it is final'
My sample runs but I now get a
com.google.gwt.user.client.rpc.SerializationException when I try to
pass an action instance via RPC as per the talk...
Any Clues? Have I missed some embarrassing and obvious point? All of
the 'reference' implementations pass simple types and skirt the
ArrayList thing.
