    Description

      Border components extended from a custom border component with <wicket:extend> fail to render in 7.7.0 (see stacktrace) and 8.0.0-M5. It renders fine with 7.6.0. The upgrade to 7.7.0 is necessary to get the fix for https://issues.apache.org/jira/browse/WICKET-6303.

      The class hierarchy is as follows:

      class MyBorder extends Border
class MyExtendedBorder extends MyBorder

      MyBorder uses <wicket:border> and includes <wicket:body/> and <wicket:child/>. MyExtendedBorder uses <wicket:extend> and is used on the page.
