5.4 List inside form is failing Could not find a coercion from type java.lang.String

[George Christman]

Hello, I'm creating a loop with a list of dates for presentation inside a
form. When I submit the form, it fails with the following exception.

org.apache.tapestry5.ioc.util.UnknownValueException

*Could not find a coercion from type java.lang.String to type
java.util.Date.*
availableValues

Configured coercions:

I'm using the following code.

<t:Loop source="workDates" value="workDate">
     <div class="col-xs-15"><div><t:output format="literal:MM-dd"
value="workDate"/></div></div>
</t:Loop>


    @Property
    private List<Date> workDates;

    @Property
    private Date workDate;

Object onActivate(TimeSheetEntity timeSheetEntity) throws Exception {
     workDates = getWorkDates(timeSheetEntity)
}


public List<Date> getWorkDates(TimeSheetEntity timeSheetEntity) {
        List<Date> workDates = new ArrayList<>();

        for (int i = -13; i <= 0; i++) {
            Calendar cal = Calendar.getInstance();
            cal.setTime(timeSheetEntity.getEndDate());
            cal.add(Calendar.DAY_OF_MONTH, i);
            workDates.add(cal.getTime());
        }
        return workDates;
    }
