The jQuery UI date picker for DateFields is working as expected with the following exception: IE 7, IE 8 and IE 9 are ignoring the dateformat setting and selecting dates result in the following US format: 12/23/2012. This fails to validate upon submit. Have tested in other browsers and the dateformat is entering correctly: eg 23 Dec 2012.
I have tried stripping out all other JS from the template as a basic test and problem persists.
I have tried setting the dateformat config for the DateField manually, and problem persists.
I have tried setting the DateField locale manually, and problem persists.
I have tried setting the DateField::set_default_config('dateformat'), and problem persists.
I have confirmed i18n::set_locale('en_GB').
Having tried all above, I cannot locate the problem, and have reverted to using a simple text field in place of the date field.
I'm running into the same issue and will have to resort to using a textfield instead of a datefield as well.
I take it nobody has found a solution yet?
