Unfinished Stubbing Detected in Mockito

I am getting following exception while running the tests. I am using Mockito for mocking. The hints mentioned by Mockito library are not helping.

org.mockito.exceptions.misusing.UnfinishedStubbingException: 
Unfinished stubbing detected here:
    -> at com.a.b.DomainTestFactory.myTest(DomainTestFactory.java:355)

    E.g. thenReturn() may be missing.
    Examples of correct stubbing:
        when(mock.isOk()).thenReturn(true);
        when(mock.isOk()).thenThrow(exception);
        doThrow(exception).when(mock).someVoidMethod();
    Hints:
     1. missing thenReturn()
     2. you are trying to stub a final method, you naughty developer!

        at a.b.DomainTestFactory.myTest(DomainTestFactory.java:276)
        ..........

Test Code from DomainTestFactory. When I run the following test, I see the exception.

@Test
public myTest(){
    MyMainModel mainModel =  Mockito.mock(MyMainModel.class);
    Mockito.when(mainModel.getList()).thenReturn(getSomeList()); // Line 355
}

private List<SomeModel> getSomeList() {
    SomeModel model = Mockito.mock(SomeModel.class);
    Mockito.when(model.getName()).thenReturn("SomeName"); // Line 276
    Mockito.when(model.getAddress()).thenReturn("Address");
    return Arrays.asList(model);
}

public class SomeModel extends SomeInputModel{
    protected String address;
    protected List<SomeClass> properties;

    public SomeModel() {
        this.Properties = new java.util.ArrayList<SomeClass>(); 
    }

    public String getAddress() {
        return this.address;
    }

}

public class SomeInputModel{

    public NetworkInputModel() {
        this.Properties = new java.util.ArrayList<SomeClass>(); 
    }

    protected String Name;
    protected List<SomeClass> properties;

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

    public void setName(String value) {
        this.Name = value;
    }
}
