Nino,
It looks like the message you are getting is misleading; probably the refactoring out of the Wicket IOC module (which both Wicket's Guice and Spring modules sit on top of now) missed changing that exception's text. "InjectorHolder has not been assigned" is caused by Wicket's Guice integration not setting it the way Spring does. (((Application.get()).getMetaData(GuiceInjectorHolder.INJECTOR_KEY)).getInjector().injectMembers(this); would probably be the right Guice equivalent of your InjectorHolder.getInjector().inject(this); If you have taken copies of the LegUp's [1] make sure you are using the latest version. If one of us finds more time later and you're still having a problem (please let us know), we can debug the Wicket code and submit a patch, or it may be that the Guice integration just isn't supposed to work exactly like the Wicket Spring integration yet t (Igor?) but I haven't had a chance to take a good look through Jira yet, but it may be covered already in a related issue [2]. Then, we should also see how the JEE contrib (and James' stuff for CDI etc) works to keep things consistent across the board for people using IOC with Wicket.
