Oracle ADF Data Control With Java List

Question

Hello
I have a question regarding Data Controls that are based on Application Modules functions. In short I created function:
public List getListOfTest() {
List allTests = new ArrayList();
allTests.add("test1");
allTests.add("test2");
allTests.add("test3");
return allTests;
inside AppModuleImp.java
I tested this implementation through AppModule Oracle ADF Model Tester and it returns test1,test2,test3. So this is OK. Now I publisher function through Client Interfaces, and I can see it know in DataControl.
So I drag and drop function on my jsf page, and render it as a button. Also i drag and droped "return"(hierarchically beeneth/inside function getListOfTest in DataControll) from Data Control and rendered it as ADF table. I was hoping that this will show: test1,test2,test3 in ADF table.
But now when I run jsf page and it is displayed in browser I get:
Object java.util of type ApplicationModule is not found
What I am doing wroong. Please help. Thx
I use JDeveloper Studio Edition Version 11.1.2.2.0

The solution is
public List<String> getListOfTest() {
List<String> allTests = new ArrayList<String>();
allTests.add("test1");
allTests.add("test2");
allTests.add("test3");
return allTests;
Problem was in generic List
