Description

Accessing a page with a Border component and a nested body fails due to NullpointerException. Seems to be working with new Wicket version 8.0.0-M7.

WicketMessage: Error attaching this container for rendering: [Page class = com.mycompany.front.wicket.TestPage, id = 0, render count = 1]

Caused by: java.lang.NullPointerException
