Wicket DateTimeField dd/MM/yy Date Validation

Question

I have a DateTimeField that I am trying to allow for 2 types of formats based on the user's preferences: MM/dd/yy or dd/MM/yy. When a user clicks DatePicker and selects a date, I am able to display the date in a DateTextField with the correct formatting. However, when I try to submit the form, I get "'date' is not a valid Date" alert, which is the default alert for the DateTimeField. Is there a way I can set, not just the pattern of the date, but the validation pattern too? I've tried implementing my own IValidator and IConverter as other posts have mentioned, but I am having no luck.

Here is the code for how I am altering the way the picked date is displayed in the DateTextField:

   DateTimeField fromDate = new DateTimeField("fromDate") { 

   private static final long serialVersionUID = 1L;

        @Override 
        protected DatePicker newDatePicker() { 
            DatePicker datePicker = new DatePicker(){ 

                private static final long serialVersionUID = 1L;

                @Override 
                protected String getDatePattern() { 
                     return ((String) getSession()
                            .getAttribute("dateFormat")).replace("yyyy", "yy"); 
                } 

         }; 
         return datePicker; 
    }

You should use a dateTextField with a custom converter:

new DateTimeField(..) {
    protected DateTextField newDateTextField(String id, PropertyModel<Date> dateFieldModel)
    {
        return new DateTextField(id, model, yourCustomConverter);
    }
}
