Hello,
I'm currently migrating a wicket / brix application from wicket 1.4 to wicket
6.23; So far most seems well, but there is a thing I'm really stuck at. My code
uses FeedbackPanel regularly like this (on many many pages/ tiles):
loginForm.add(new FeedbackPanel("feedBack") {
private static final long serialVersionUID = -2594094600209896717L;
@Override
public boolean isVisible() {
return loginForm.hasError();
}
}.setEscapeModelStrings(false));
and this worked fine in wicket 1.4; With wicket 6 now if I access a page
containing this I get
[2016-05-14T13:14:48.163+0200] [Payara 4.1] [WARNING] [] [javax.enterprise.web]

.... repeating the error dozens of times;
Did anything change here that makes the good old isVisible() not usable anymore?
Best,
Korbinian
