ORA-06531: Reference to uninitialized collection

[prasannakhapli]

I am invoking one Package Procedure in a PLSQL Block.The Procedure is

PROCEDURE createFault(
reportedBy IN varchar2,
reportedDate IN date,
description IN varchar2,
priority IN number,
workgroup IN WorkgroupID,--Subtype as varchar2(20)
creatingUser IN UserID,--subtype as varchar2(40)
faultAttributes IN AttributesList,--collectiontype MAY BE NULL
initialClassifi cations IN AttributesList,--collectiontype MAY BE NULL
createdFaultId OUT FaultID, subtype number
returnStatus OUT CallStatus);


Invoking Block:



declare
v_reportedBy varchar2(40):=' Prasanna';
v_reportedDate date:= sysdate ;
v_description varchar2(80):=' Test';
v_priority number:=1;
v_workgroup varchar2(20):=' UNIT_1';
v_creatingUser varchar2(40):=' CLARITY_DEMO';
returnstatus CallStatus;
v_faultAttribut es AttributesList := NULL;
v_initialClassi fications AttributesList := NULL;
v_createdFaultI d number;

begin
P_FAULTMGR_API. createFault(v_r eportedBy,v_rep ortedDate,v_des cription,v_prio rity,v_workgrou p,v_creatingUse r,
v_faultAttribut es,v_initialCla ssifications,v_ createdFaultId, returnstatus );

DBMS_OUTPUT.PUT _LINE('Fault NUMBER :' ||v_createdFaul tId);
DBMS_OUTPUT.PUT _LINE('Response Code : ' ||returnstatus. CODE);
DBMS_OUTPUT.PUT _LINE('Response Text :' || returnstatus.MS G);
DBMS_OUTPUT.PUT _LINE('Response Type :' || returnstatus.CO DETYPE);
END;


After Execution in SQL Plus:

Error in p_faultmgr_api. createFault ORA-06531: Reference to uninitialized
collection
