Re: Help with regular expression
Thanks but I don't want to do that because if validation fails for both cases
(regular expression and length vaildator) then two error messages will be
displayed and I just want to have a single error message (e.g. "Email
address must be of the form ... and between 1 and x characters long.")

Are you using h:message or h:messages to display the error message? If you
should use h:message I think only one message will be displayed.

there are several options for handling this.
1) If you use two validators and only want one message to be displayed, you
can use a phase listener to detect the condition and remove the extra
message
2) You can use a validator method in your backing bean to handle both
validations and display the appropriate error message.
3) You can write your own custom validator to do both validations. With this
approach, the validator could be used easily in multiple pages.
