Hi guys, where does AccessDeniedException exist?
I guess it was just one fictional example . ..
Thiago, love the mixin
approach, not entirely sure how to create one though.
To begin with, if you haven't yet, you need to understand what a Tapestry
mixin is, how it works and what can it do. It's a little bit surprising at
first, but it's very, very powerful. Take a look at the documentation and
the JumpStart examples.
The mixin itself is just copying your code to a new class under the mixins
subpackage:
public class HandleAccessDeniedException {
Object onException(Throwable cause) {
if (cause.getCause() instanceof AccessDeniedException) {
if (request.isXHR()) {
return loginPage;
}
}
return null;
}
}
