[xwiki-users] Using Validation RegEx in Class Properties

Hello, Looking for help on getting the Class Properties fields to validate in a form using regular expressions. I went through the “Creating a form with Validation and Tooltips” tutorial, but cant seem to get my own example working. I have added the regex to the class property, but where exactly does the $doc.validate() and *<input* type="hidden" name="xvalidate" value="1" */> * code go? If I add them to the ClassSheet it just shows up as text and doesn’t seem to be running. What am I missing here? Any help is appreciated! Thank you, Alena
