Convert dateToString | stringToDate

Controller Code:-

Date date = (Date)oaapplicationmodule.findViewObject("AddNewAssignmentVO").first().getAttribute("StartDate");
Date edate = (Date)oaapplicationmodule.findViewObject("AddNewAssignmentVO").first().getAttribute("EndDate");


if (date != null && edate != null)
                       {
                        String Xs11 = oapagecontext.getOANLSServices().dateToString(date);
                        String Xs12 = oapagecontext.getOANLSServices().dateToString(edate);
}

In the same way we can convert String to Date

oapagecontext.getOANLSServices().stringToDate("xxxx");
