Wicket Date Field Validation
Hi,
I am working on date fields and have problems with the validation. I
have referred to the link below which helped me.
http://www.nabble.com/Strict-4-digit-year-for-DateTextField--td18656889.
html
So I have subclassed the PatternDateConverter and have set the pattern
as,
dateFormat = ^(\\d{1,2})/(\\d{1,2})/(\\d{4})$;
I have 2 date fields, start_date and end_date. The start_date is a
required field and the end_date is not.
some code
pdc = new
StrictPatternDateConverter(DateUtil.getDateFormatOnLocale(getLocale()),
false);
more code
startDateField = DateTextField.withConverter(startDate, new
PropertyModel(this, startDate), pdc);
startDateField.add(new TMPDatePicker());
form.add(startDateField);
endDateField = DateTextField.withConverter(endDate, new
PropertyModel(this, endDate), pdc);
endDateField.add(new TMPDatePicker());
form.add(endDateField);
more code
This works fine ie it does not allow entry of 03/03/09 or
03/03/-2009
BUT, the end_date becomes a required field. I have to enter the end_date
to click 'Save'. Else it complains that an invalid date has been
entered.
But my end_date is not a required field.
So if I replace it with,
endDateField = DateTextField.forDatePattern(endDate,
DateUtil.getDateFormatOnLocale(getLocale()));
endDateField.withConverter(endDate, pdc);
endDateField.add(new TMPDatePicker());
It allows, 03/03/-2009 and 03/03/09. Why does it allow the '-' sign.
It computes it to a value and displays a year.
My application has several date fields and I need to validate them.
I am a newbie to Wicket and have looked up the archive quite a bit to
find a solution.
Can someone please tell me a solution to my date validation problem?
Thanks very much

Possibly the simplest approach would be to use a regular expression that
allows an empty string like making the whole expression optional by
surrounding it with paranthesis and adding the optional operator '?'
after it. This allows the empty string OR a valid date but nothing else:
dateFormat = ^((\\d{1,2})/(\\d{1,2})/(\\d{4}))?$;
