substituteDate function doesn't respect date pattern
----------------------------------------------------
Key: WICKET-2427
URL: https://issues.apache.org/jira/browse/WICKET-2427
Project: Wicket
Issue Type: Bug
Components: wicket-datetime
Affects Versions: 1.3.7
Reporter: Reinout van Schouwen
The function Wicket.DateTime.substituteDate in wicket-date.js fails to
correctly format dates.
Example: create a datetextfield like this
DateTextField birthDate = DateTextField.forDateStyle("birthdateFromAndTo",
"M-");
and add a DatePicker to it:
birthDate.add(new DatePicker());
The datetextfield will only validate when the input matches 'd-MMM-yyyy' (for
my locale, at least) as can be verified by executing birthDate.getTextFormat().
This translates to '17-augustus-2009' for today's date.
However, when a date is selected in the datepicker, it puts '17-8-2009' in the
DateTextField. The reason is, I believe, that subsituteDate() assumes that all
fields in the pattern are numbers. Instead, it should execute a proper date
formatting. The function either should call the Wicket side to format the input
date, or it should do it in javascript. On
http://www.timdown.co.uk/code/simpledateformat.js I found an Apache licensed
piece of javascript code that should do the work (it misses l10n though).
