Reg. changing Default Validation of WebDynpro

Hi xperts,

I have a input field which mapped to date format attribute. Now when i try to enter string in that and press any button in that screen, it throws me with a error message like "Enter the date in the format 11/25/1987".

Is it possbile to change this message via coding??.

Note that i cant keep the input as string as i will not get the calendar next to the input field.

Thanxz
