Validate Pattern Not Working for Reg Expression

Hi,

Wishing you all a very happy & prosperous new year.

I am trying to put a validation on one of the attribute for Email. Following the manual , expression I am using is :

!d2:validatePattern(#{email},’^\w+([.-]?\w+)@\w+([.-]?\w+)(.\w{2,3})+$’)

Which is not working as it validate false every time even if we enter a valid email i.e: sourabh@gmail.com

However I have checked d2:validatePattern for other expressions like :

!d2:validatePattern(A{name},’[^\d]*’)

Which is working fine for not contain numbers.

The Reg Expression I am using for email is working fine on normal html.

Has anyone used the validate pattern for email before?
