3 Levels Master Detail View Object with Java class interface

Question

Hi Developers,
I've created 3 tables with one to many relations as below
BOARD ------<- APPLICANT ------<- QUALIFICATION
a board includes many applicants and an applicant includes many qualifications.
When I add these tables to a Fusion Project, JDeveloper 11g helps me to add the Entity Links and View Associations automatically.
Then, I defined these relations in an ApplicantModule's Data Model as below.
[+] BoardVO1
      |
      |--[+] ApplicantVO1
               |
               |--[+] QualificationVO1The problem is: I cannot write any function in QualificationVO and publish it by client interface.
I created a simple function with a single line (System.out.println(...) ) in QualificationVOImpl.java. and selected it in Client Interface. But when I execute it from the ApplicantionModel for testing, an oracle.jbo.NoObjException JBO-25003 is raised. with message: Object ... ApplicantVO1 of type ApplicationModule not found.
Has anyone tried to implement some coding in the third level of a master details view structure as my example? How do you make it works?
I'm using JDeveloper 11.1.1.3 with ADF BC.

Samson,
Looks like a bug (probably with the application module tester). I created your tables:
create table board(board_id number primary key not null);
create table applicant(applicant_id number primary key not null, board_id number not null);
create table qualification(qualification_id number primary key not null, aplicant_id number not null);
alter table applicant add a_fk foreign key(board_id) references board;
alter table qualification add q_fk foreign key(aplicant_id) references applicant;I created a JDev project and got the same results. I've e-mailed a test case off to Frank.
Frank - the method is indeed exposed on the VO instance, and I tried testing that way, but the AM tester gives the error as if it is looking for an AM instance with the VO's name.
