Problems in sending nested arraylists of complex data type through soap model.

[Muddy Mind]

I am having a trouble with sending nested arraylists of complex data types through ksoap library in android. The problem in that I get the response and can parse it fine but when I want to send the model back to service it contains nested arraylists and when sending it puts them to null. I have tried every way and trick but it haven't worked. Below is the example code for what I am trying to share. 

public class ExampleModelA implements Parcelable,KvmSerializable {
 public int Id;
 public int C;
 public int D;
 public String E;
 public int G;
 public String E;
 public Date G;
 public int Y;
 public Date H;
 public int U;
 public ArrayList<NewModel> abc= new ArrayList<>();
 public ArrayList<Enumerations.TestTypes> abcd= new ArrayList<>(); 



Now inside NewModel I am sending this list:

public class NewModel implements Parcelable, KvmSerializable{
 
 public int Id ;
 public int Q;
 public int W;
 public int E;
 public String R;
 public int T;
 public String Y;
 public boolean U;
 public int I;
 public ArrayList<AnotherModel> NewModel2;
 public String O;
 public Date P;
 public int A;
 public Date S;
 public int D;


    
Now inside AnotherModel it's another list:

public class AnotherModel implements Parcelable,KvmSerializable, Marshal {

 public int Id ;
 public String Name ;
 public String Purpose ;
 public String Threshold ;
 public String Sources ;


And now when I send this list in service the newModel turns null so I am unable to send the request. Kindly help me in this regard.

thanks;
