ricotero cordoes commented on TRINIDAD-1028:
--------------------------------------------

friend this working fine to me(sorry for the bad english).

I tink you need make a class call Person with the method getkids.

I am 2 classes, Person and Test, with a method getModel and a "TreeModel model; " attribute. 

Remember this in Person 

 public String toString()
 {
     
     return this.getName();
     }

god luck
