Currently wicket-spring 1.5 depends on spring 2.5 (specifically org.springframework:spring:2.5.x:jar) which collides when folks are upgrading to spring 3, since spring 3 doesn't have an aggregate library any more.
If we chose to upgrade to spring 3, should we depend on spring-web or spring-core? Martijn -- Become a Wicket expert, learn from the best: http://wicketinaction.com
