OWB Can't Import Existing Package with Collection Data Type as Arguments

Question

I created a package and compiled it successfully as the follows:
+++++++++++++++++++++++++++++
CREATE OR REPLACE PACKAGE PACKAGE_TEST AS
TYPE Num_LIST IS TABLE of NUMBER INDEX BY BINARY_INTEGER;
FUNCTION TEST_FUNCTION1 ( arg1 NUMBER, arg2 NUMBER) RETURN NUMBER;
FUNCTION TEST_FUNCTION2 ( args NUM_LIST) RETURN NUMBER;
END PACKAGE_TEST;
CREATE OR REPLACE PACKAGE BODY PACKAGE_TEST AS
FUNCTION TEST_FUNCTION1 ( arg1 NUMBER, arg2 NUMBER) RETURN NUMBER IS
ln_sum NUMBER;
BEGIN
ln_sum := arg1 + arg2;
     RETURN ln_sum;     
EXCEPTION
WHEN OTHERS THEN
RETURN -10000;     
END TEST_FUNCTION1;
FUNCTION TEST_FUNCTION2 ( args NUM_LIST) RETURN NUMBER IS      
     ln_sum NUMBER;
BEGIN
ln_sum :=0;
     FOR i IN 1.. args.COUNT LOOP
     ln_sum := ln_sum + args( i );     
     END LOOP;     
     RETURN ln_sum;     
EXCEPTION
WHEN OTHERS THEN
RETURN -10000;     
END TEST_FUNCTION2;     
END PACKAGE_TEST;
++++++++++++++++++++++++++++++++++++++++
Then I tried to import the package into OWB (9.2). The problem came: all the package body and
the specification of TEST_FUNCTION1 were imported, but the package specification of
TEST_FUNCTION2 couldn't be imported. The IMPORT FILTER gave an error message:
"TEST_FUNCTION2: Argument Data type is not supported".
How to resolve this problem? It is very import for our project, since we have to import some
packages with user_defined collection data types as arguments.
Thank you.

Hi Lushu,
Unfortunately this is indeed not supported and I would not know how to work around this one. The only way I guess that this would work is to not import it, and then use Expressions to call the function with inputs.
