Emond Papegaaij created WICKET-5264:
---------------------------------------
Summary: CDI Injection no longer working on anonymous classes
Key: WICKET-5264
URL: https://issues.apache.org/jira/browse/WICKET-5264
Project: Wicket
Issue Type: Bug
Components: wicket-cdi
Affects Versions: 6.9.0
Reporter: Emond Papegaaij
Priority: Blocker
The changes made for WICKET-5226 (no longer injecting anonymous inner classes)
breaks our applications badly, and I suspect we are not the only one. The
following pattern is quite common:
add(new Link<Void>("rest") {
@Inject
private AccountRestResourceClient accountClient;
@Override
public void onClick() {....}
}
In Wicket 6.9.0, this no longer works: accountClient will not get injected
because the Link is an anonymous inner class. To make things worse, even in
concrete classes, you can't rely on injection to work, because someone could
subclass your class as an anonymous inner class and injection will again not
work.
This change was made because Weld 2.0 throws an exception when trying to create
an InjectionTarget for anonymous classes. This will be reduced to a log-warning
in 2.0.2: https://issues.jboss.org/browse/WELD-1441
