Error when passing Date to ViewObject

Question

I am capturing Date and 1 string on form and passing as bind variables to a query in Vo.
I get error oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation.
The Vo executes fine if the query has only date parameter as a bind variable
but it fails when there are 2 or more bind variables along with date as a bind variable.
I am capturing the date in Co as -
String runDate = pageContext.getParameter("Rundate");
And executing VO in AM as -
vo.setWhereClauseParams(null);
vo.setWhereClauseParam(0,runDate);
vo.setWhereClauseParam(1,interface_code);
vo.executeQuery();
and VO query is
select a, b, c
from table where interface_id = (select interface_id from table where interface_code = :2) and
(payroll_id like 'XX' or payroll_id = 'HEADER') and output_rec_type in (select distinct output_rec_type from table
where interface_id=(select interface_id from table where interface_code = :2) and payroll_id like 'XX') and
run_date = TO_DATE((to_char(trunc(to_date(:1)),'DD-MON-YYYY') ),'DD-MON-YYYY')
The strange thing is that , the VO executes fine if I hard code value for bind variable :2 ,but if fails otherwise.
Are there any limitations in using date as bind variable or I am doing something wrong way.
Thanks in Advance,

By the way instead of using date format directly in query, u can pass java date object in bind variables, it will make your code safe, even if user enters date in some other format by changing his user level preference.
