Hi! It sounds like you are not referencing the correct wicket-request dependency.
Did you check your maven dependency tree to ensure there are no old (or duplicate/multiple) versions of wicket dependencies being resolved?

I created a new pom.xml using your Quick Start Wizard, checked the old dependencies for new versions, inserted the dependencies to the new pom.xml and fixed the compile errors. But deploying the war-file to tomcat 8, I'm receiving the following error: java.lang.NoSuchMethodError: org.apache.wicket.request.mapper.ParentPathReferenceRewriter.<init>(Lorg/apache/wicket/request/IRequestMapper;Ljava/util/function/Supplier;)V I would be grateful for any tip on where the mistake might be or to debug this problem.
