Userforms datefield in locale that doesn't use en_US format doesn't validate

[guy_van_bael]

Userforms datefield is never validated if sitelocale is set different to en_US (e.g. i18n::set_locale(‘nl_BE’) When using this the datefield in Userforms never validates. You always get the error_message that the date is not valid.
Can somebody help me out?

Another issue with this that IE and Safari don’t support native html5 Datepicker. Is it possible to use the old jquery datepicker instead of the nativ html5 one?

thanks

I read all the GitHub discussion about this and it seemed that things were added in some SS4 releases and were then changed and removed in later versions. What’s the trick please? $dateField = new DateField(‘FromDate’); //$dat…

Sorry can’t help with your locale validation.
