Hello,
I have the following problem:
If some user is entering a already used email adress or username I wan't to
let appear a link (s:link/button) to the "forgott password" page in a form?
I'm not sure how to solve it with my custom email validator?
Has someone an idea how I could solve that?
Thx for any help
Best regards
Ben
Validator

validation"));
}

{
String expression = "....@.+\\.[a-z]+";
// Make the comparison case-insensitive.
Pattern pattern = Pattern.compile(expression,
Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(eMail);
