Injection of Bound Instance Fails with Exception
------------------------------------------------
Key: WICKET-1130
URL: https://issues.apache.org/jira/browse/WICKET-1130
Project: Wicket
Issue Type: Bug
Components: wicket-guice
Affects Versions: 1.3.0-beta4
Reporter: Daniel Spiewak
If I try to inject an explicitly bound instance into a component, injection
fails with an exception in the creation of the CGLIB proxy:
java.lang.IllegalArgumentException: Superclass has no null constructors but no
arguments were given
Stupidly, I forgot to save the whole stack trace and the code is now gone from
my codebase (since I needed it to work). To repeat:
@Override
public void configure() {
bind(EntityManager.class).toInstance(manager);
}
Seems wicket-guice is assuming that it needs to create a new instance of
everything that's injected, and since EntityManager doesn't have a no-args
constructor, such an action fails. Just an assumption anyway...
