validate h:textInput only if any value is entered

[nikh123123]

Hey guys,

I'm trying to add regex validation to an optional field

<h:inputText
            id="txtContact" 
            value="#{user.contact}"
            required="false"
            validatorMessage="Invalid phone number"
            maxlength="10">
              <f:validateRegex pattern="\d{10}" />
              <rich:validator/>
</h:inputText>

This valides the text field even if its kept empty. I want it to be validated only if user enters something. How to achieve this?

Hi Nikhil, it seems like an issue (validation should not be processed when @required=false and input is empty), could you please fire RichFaces JIRA issue [1]?

But as a workaround, you can fix your pattern to state something like ^(|\d{10})$ - it means "empty or 10 decimals".

I think that http://andyschwartz.wordpress.com/2009/07/31/whats-new-in-jsf-2/#validation-empty-fields also should be considered. I will comment the issue accordingly.
