Parameter type conflict from Toplink 11g when passing ArrayList as input

Question

When passing ArrayList as an input to a StoredProcedureCall, I am getting the following stacktrace:
t] Exception [TOPLINK-4002] (Oracle TopLink - 11g Release 1 (11.1.1.0.0) (Build 080121)): oracle.toplink.exceptions.DatabaseException
[junit] Internal Exception: java.sql.SQLException: Parameter Type Conflict
[junit] Error Code: 17012
[junit] Call: BEGIN XL_SP_ASSIGN_EVENTLIST(?, usrName=>?, assignUsrkey=>?, assignGrpkey=>?); END;
[junit] bind => [null => eventIdList, FOO1, 117, 0]

[junit] at oracle.toplink.internal.databaseaccess.DatabaseAccessor.basicExecuteCall(DatabaseAccessor.java:534)
[junit] at oracle.toplink.internal.databaseaccess.DatabaseAccessor.executeCall(DatabaseAccessor.java:467)
Here is my code snippet to pass ArrayList as input parameter :
StoredProcedureCall spc = new StoredProcedureCall();
spc.setProcedureName(procedureName);
spc.addUnamedInOutputArgument("eventIdList", "eventIdList", Types.ARRAY,
"EVENTIDS", ArrayList.class);
String argLoggedInUsrName = "usrName";
String argAssignedUsrKey = "assignUsrkey";
String argAssignedGrpKey = "assignGrpkey";
spc.addNamedArgument(argLoggedInUsrName);
spc.addNamedArgument(argAssignedUsrKey);
spc.addNamedArgument(argAssignedGrpKey);
ValueReadQuery query = new ValueReadQuery();
query.setCall(spc);
query.addArgument("eventIdList");
query.addArgument(argLoggedInUsrName);
query.addArgument(argAssignedUsrKey);
query.addArgument(argAssignedGrpKey);
Vector args = new Vector();
ArrayList eventIdList = new ArrayList();
eventIdList.add(new Long(50000));
args.add(eventIdList);
args.add(loggedInUsrName);
args.add(assignedUsrKey);
args.add(assignedGrpKey);
eventIdList = (ArrayList) session.executeQuery(query, args);
This code chunk was working with an earlier build. Would really appreciate any inputs on the error seen.
Please note - the EVENTIDs type in the pl/sql procedure is defined as a VARRAY(100) of NUMBER

Well I posted a thread several weeks ago...see this thread below
trying to get used to sql*plus, running and creating a simple procedure
and someone made comments about the select query leading to sql injection. Now I am trying to understand the true case behind that. I have an idea made it is because of the first concatenation in the parameter or not. Not sure.
