SQL*PLUS VS HTML IGU APEX (Application Express 3.2.1.00.12)

Question

Hello,
Could anybody gives me a clue about the following?
Thanks for any help.
Claude
A did this:
CREATE OR REPLACE TYPE "A" AS OBJECT (v_a NUMBER) NOT FINAL;
CREATE OR REPLACE TYPE "B" UNDER A (v_b NUMBER);
CREATE TABLE "TA" OF "A";
INSERT INTO TA VALUES(A(1));
...some other similar inserts...
INSERT INTO TA VALUES(B(1,2));
Till now all is ok...but after I try to launch the following simple command:
SELECT REF(p) FROM TA p;
If I launch it from the SQL*PLUS the result is OK ->
REF(P)
000028020981708518CF81BCD2E040007F01011CDB81717581F4E5C8A9E040007F010109B1010000

Answer 1

the problem is reproducoble on apex.oracle.com (current version 4.0.0.00.46)
Who can say that it is BUG or FEATURE?
