Validation for non-required field

jsf-2, primefaces, validation

Solution

your `inputText` value is being validated against your `<f:validateRegex pattern=".+@.+\.[a-zA-Z]+" />` and if its value not valid you getting the error , so you need to improve your regex so it will match your pattern or accept empty string...

So wrapping it with `()` and adding a `?` should do the job

Try

<f:validateRegex pattern="(.+@.+\.[a-zA-Z]+)?"/>

Problem

I have these lines of code to validate for an e-mail address: ``` <h:outputText value="#{labels.eMail}: " /> <p:inputText size="30" maxlength="50" validatorMessage="Please provide a valid e-mail address" value="#{personelView.eMail}"> <f:validateRegex pattern=".+@.+\.[a-zA-Z]+" /> </p:inputText> ``` When I leave the e-mail address field empty and submit the form it gives validation error. Why JSf is doing this? Isn't it supposed to just validate e-mail field with the above code? I even tried adding: ``` required="false" ``` still no good. Does anyone have any idea about this case?
