GWT Arraylist

Question

I have two different model class,

public class ModelDto implements IsSerializable{
     public ModelDto {}
     private Integer id;
     private String name;
     private ArrayList<Test> name;
}

public class Test implements IsSerializable{
     public Test {}
     private Integer id;
     private String name;
     private ArrayList<Test> name;
}

I want to make a RPC call like

ModelDto getModel();

How to achieve this? I know that the issue is basic serialization. but I want to know that how to pass a ArrayList in RPC If not posible any alternatives?.

Which bit of the GWT RPC demo is giving you a problem? https://developers.google.com/web-toolkit/doc/latest/tutorial/RPC — John3136, Mar 06 '13 at 02:03
I use same tutorial but I cant pass a ArrayList on client side there always null — Mayank Pandya, Mar 06 '13 at 02:13
There should not be any issue in serializing ArrayList. Can you post the code that reproduces the problem? — Ganesh Kumar, Mar 06 '13 at 03:21
Passing an ArrayList should work just fine. Could the problem be somewhere else? Can you include the code for your remote service implementation in your question? — David Levesque, Mar 06 '13 at 03:22

Sounds like problem with your implements IsSerializable I suspect your class not implement com.google.gwt.user.client.rpc.IsSerializable.

It should implements either java.io.Serializable or GWT com.google.gwt.user.client.rpc.IsSerializable.(No problem with both together).

And about your default constructor .It should an empty constructor. e.g

 public ModelDto() {

}

Most of the problems raises with these two points only if you still facing the issue after made the above changes like package structures...etc please refer this.
