Ever used the Table API (TAPI) with object type in the DB?

Question

Hi all,
We are trying to generate the table API of a table that has a column defined by an object type. It works without problems if that column always has a value (is instantiated in object term). The problem is when we update a row where the column is null (all attributes of the object are null thus the object is not instantiated).
The "before update row" trigger of the Table API fails with error "ora-30625-method dispath on NULL SELF argument is disallowed".
Any of you guys made it work? If so, how?
Thanks

Hi friends,
I have a procedure with object type IN OUT parameters which is used for fetching status. We are calling this from Java. But I want to call it from oracle for testing purpose. I am trying from my end but not able to do it as of now. This is the first time I am dealing with object type.We need more information. What is wrong? Your code looked okay and you did not mention any Oracle errors. What is happening that should not be or not happening that should be?
You can call the procedure with a simple call in PL/SQL but will not be able to use it in SQL because 1) it is a procedure and 2) it has an OUT argument. A sample call should look something like (untested)
declare
   x rec2;
   y rec3;
begin
  --use the arguments rru was defined with as the arguments in the same order: types rec2 (x), rec3 (y)
  rru(x,y);
end;>
Any help would be appreciated.
Details are given below.
CREATE OR REPLACE TYPE REC1 AS OBJECT
(RELAY_USAGE VARCHAR2(30)
,STATE VARCHAR2(1)
TYPE REC AS TABLE OF REC1;
CREATE OR REPLACE TYPE REC2 AS OBJECT
(GSRN VARCHAR2(18)
,METERING_POINT_NAME VARCHAR2(80)
,RELAYS REC)
CREATE OR REPLACE TYPE REC3 AS OBJECT
(INFO VARCHAR2(2000)
,STATUS NUMBER
PROCEDURE RRU(
rcRelayControl IN OUT REC2
, rcResp IN OUT REC3)
IS
BEGIN
APKG.GetDetails(rcRelayControl, rcResp);
IF rcResp.Status = BPKG.iStatusFailure THEN
rcResp.Info := BPKG.Get_Message('20889', rcResp.Info);
END IF;
END RRU;
How to call this procedure in oracle?
Thanks.
