Description

AbstractTransformerBehavior#originalResponse is not serializable what causes the following exception while trying to use DebugBar component (sizeOf(object)).

WARN - WicketObjects - Unable to determine object size: [Page class = com.mycompany.HomePage, id = 0, render count = 1]

The simplest solution would be to add 'transient'

private transient Response originalResponse;
