[date-picker] Allow 2-digit years (i.e. dates before year 100)

[zanonmark]

Description

When (Enhanced)DatePicker is set to use "dd/MM/yyyy" as pattern and "dd/MM/yyyy", "dd/MM/yy" as parsers, inputting a year before 100 will result in a wrong date being reformatted.

i.e.: 13/01/0040 or 13/01/40 (13th January 40, not 1940 or 2040)
-> result: 1940-01-13

Expected outcome

The string should be parsed properly as 0040-01-13.

At this point, this component is unable to handle dates before year 100.

Thanks,

I read this CookBook recipe: instead of initializing the JavaScript Date() object as a (year, month, day) triple in i18n.formatDate(), shouldn't it use an ISO-8601-formatted date string?
I tried it at home and it works...

Thanks,

If the issue is about how the Enhanced Date Picker parses the date string, and not about vaadin-date-picker specifically, please report the issue in https://github.com/vaadin-component-factory/enhanced-date-picker

No, it's also for DatePicker: try https://vaadin.com/components/vaadin-date-picker/java-examples, pick the first example and enter 3/17/0084 (US locale), it will become 3/17/1984.

EnhancedDatePicker just inherits this issue.

@web-padawan (I think the "waiting for author" tag is wrong here...)

Sorry about the lack of response since the last comment.
This is now supported with the custom date format feature available in Vaadin 22:

https://vaadin.com/docs/latest/ds/components/date-picker/#date-format

Closing as fixed.
