makes sense to me - FWIW by default Guice considers injection of null to be an error, but you can allow this by marking the field as @Nullable (you can actually use any annotation type, as long as its simple name is Nullable - this means you can "re-use" IntelliJ and JSR305 annotations) > Cheers > Niclas > > _______________________________________________ > qi4j-dev mailing list > [email protected] > http://lists.ops4j.org/mailman/listinfo/qi4j-dev > -- Cheers, Stuart
