Here is my code:
String referrer = referrerField.getValue();
if (referrer != null) {
setRedirect(referrer); <===============================
} else {
setRedirect(HomePage.class);
}
return true;
Thanks in advance,
Gilberto

Yes, you're correct! One exception two line before was causing
(referrerField) it.
Sorry, sometimes the error is on your face but you don't see anything!
Thanks,

I think what happens here is referrerField returns an empty string "".
Probably not where you would like to redirect to.
You should probably change the code slightly to redirect to HomePage
if the referrer is null or empty:
String referrer = referrerField.getValue();
if (StringUtils.isNotBlank(referrer)) {
setRedirect(referrer);
...
kind regards
