You have a model class in your action to populate, one of the property is a java.util.Date. You register your own DateConverter (for i18n purpose ...) When WW2 populates the Action after a form submission, you have 2 cases : 1/ The string represent a date, and the converter can parse it and store it in the model class. No pb. 2/ The string doesn't represent a date, your converter surely returns a NULL value. The date property in the model class is set to NULL. You can always validate that the property MUST be not null, but the main aim is to warn the user it is an invalid date.
So my question is : if validation triggers after populating the model class, how can you validate an input parameter is not in a bad format ? Cheers.

The validators just validate the properties.
