Is it possible to set bind variable for picklist?? for messageChoice

Question

we are trying to develop one new page in local JDeveloper.
we have requirement for passing a bind variable to a picklist. is it possible?
Item Type : messageChoice
Query:
SELECT DISTINCT TO_CHAR (effective_date, 'YYYY') TYPE
FROM pay_assignment_actions a, pay_payroll_actions b
WHERE a.payroll_action_id = b.payroll_action_id
AND assignment_id =
(SELECT assignment_id
FROM per_assignments_x
WHERE person_id = :person_id AND primary_flag = 'Y'
AND assignment_type = 'E')
AND a.action_status = 'C'
AND b.payroll_action_id IN (SELECT payroll_action_id
FROM pay_payroll_actions_v
WHERE action_type IN ('P'))
AND b.payroll_action_id IN (SELECT payroll_action_id
FROM xxilo_pre_payments)
ORDER BY 1 DESC
processRequest() code:
PayslipAMImpl am=(PayslipAMImpl)pageContext.getApplicationModule(webBean);
YearPicklistVOImpl yvo=(YearPicklistVOImpl)am.getYearPicklistVO1();
Number t = new Number(pageContext.getEmployeeId());
yvo.setWhereClauseParams(null);
yvo.setWhereClauseParam(0,t);
for this query & code we are getting
ERROR:
java.sql.SQLException: Missing IN or OUT parameter at index:: 1
if we hardcoded person_id in query to some value then we are getting results without any error.

user603084 ,
In the query you have specifies bind variable as :person_id , but in your VO execution code you are setting value for bind variable :1
yvo.setWhereClauseParam(0,t);
You need to change the bind variable in query , like :1
and then execute the query of VO, as you have done. Also do executeQuery, after setting bind variables.
