I want to apply the 'dd/mm/yyyy' in project settings-->edit language-->custom date and time formatting --> date format * to override the 'mm/dd/yyyy' of english united states ,but it does not work ! does not work means that I expect the date format for all date widgets or fields either in data-grid or data-view should be shown like for example (24/5/2011) but it is still shown as (5/24/2011)
This issue has been fixed in 2.5.5, from the release notes:
"Ticket 7648: Fixed: a datepicker in a dataview didn't pick up the custom format settings specified on language level."
Beware that the setting should read dd/MM/yyyy and not dd/mm/yyyy.
