Apex 3.2
I have a field called P14_START_DATE.
The display as type is Date Picker (DD.MM.YYYY).
Now if the user uses the pop up calendar, the field is populated with eg 07.12.2013.
I have 2 standard validations, not null and item specified is a valid date.
If the user decides to type in the date, they can use a different format, eg 07/12/2013, which I do not want to happen.
How can I validate the field, so they get an error if they do not use format dd.mm.yyyy
