TestObject List issues

Hello everyone,

I have got following following two public classes:

public class TestObjectContainer{
public ArrayList<TestObject>ChangeOrderList=new ArrayList<TestObject>();
}

Then I have got:

public class ReadTestData
{

public TestObjectContainer fillData()
{

Object ChangeOrderTxt;

TestObjectContainer result=new TestObjectContainer();
int n=0;

List<TestObject>iList=new ArrayList<TestObject>();
iList=(desktop.findAll("//RumbaLabel[@caption='D-******']"));

for(TestObject label: iList) {
ChangeOrderTxt=(label.getProperty("caption")); //my String 

//This is what I have tried with below:

System.out.println(ChangeOrderTxt);
result.ChangeOrderList.addAll(n++, iList); 

// END

}

}

}

I get error this methot must return a result of type TestObjectContainer

Could someone help me?

Thank you in advance

Regards
