How to see refcursor data while debugging

Question

Dear Guru,
I have below procedure.
create or replace
PROCEDURE Main_Proc
RS_1 OUT TMRS_UTIL_PKG.RefCsr
AS
L_Excecution_Status NUMBER;
L_Sql_Code VARCHAR2(1000);
L_Sql_Error VARCHAR2(1000);
a NUMBER;
BEGIN
-- Initialize Execution Status.
G_Excecution_Status := 0;
G_Sql_Code := 'C';
G_Sql_Error := 'E';
DBMS_OUTPUT.PUT_LINE('Entered in Main_Proc.. ');
-- Return Resultset
OPEN RS_1 FOR
SELECT 'This output is from Main_Proc' AS Main_Proc_OP
FROM DUAL;
DBMS_OUTPUT.PUT_LINE('Left Main_Proc.. ');
G_Excecution_Status := L_Excecution_Status;
G_Sql_Code := L_Sql_Code;
G_Sql_Error := L_Sql_Error;
EXCEPTION WHEN OTHERS THEN
G_Excecution_Status := 1;
G_Sql_Code := SQLCODE;
G_Sql_Error := 'In Main_Proc SP => '||SQLERRM;
END Main_Proc;
I just want to see output contain in RS1.
I am using SQL Developer 3.0
Could anybody help me.

When running a procedure with output cursor variable(s) the result is in structured output window (modulo bugs exposed in EA1).
You are asking how to view cursor data during debuging, however, and support of complex datatypes, cursor including, is limited. On the other hand, I can imagine that during debuging session you would step inside the calling procedure, where you would extract cursor data row-by-row into some other data structures. The idea I fail to understand is why somebody is not satisfied watching those data structures themselves. As Java developer, I have never peeked into the content of ResultSet (which is essentially client-side cursor in Java)!
