Description

Because at org.apache.wicket.util.lang.PropertyResolver.getGetAndSetter(PropertyResolver.java:439) throws a WicketException, the component location etc are not shown which makes it hard to track down. This patch causes the component detail to be shown shown, to help track down problems.
