Maybe I didn't explain it precise enough, the subclass ain't the right place
to do that cause my usecase is like:
class Super {
onBeforeRender() {
if (!isValid()) {
throw Abort...Exception(404);
}
}
abstract boolean isValid();
}
class Sub extends Super{
boolean isValid() {
return false;
}
}
to see it "in action" take a look at the quickstart attached to the jira
issue :)
