Igor Vaynberg resolved WICKET-1130. ----------------------------------- Resolution: Won't Fix Assignee: Igor Vaynberg no easy way to fix this. > 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 > Assignee: Igor Vaynberg > > 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.
