>                 URL: https://issues.apache.org/jira/browse/WICKET-278
>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket
>    Affects Versions: 1.3
>            Reporter: Alastair Maw
>             Fix For: 1.3

> This manifests itself with lots of java.io.NotSerializableException: wicket.response.StringResponse and errors like this:
> 08:58:09,083  WARN Objects:1287 - Size of failed of object: wicket.markup.html.HeaderPartContainer
> Al says:
> The errors are caused by the Wicket exception page (which is why there  are a million components - they're all the Labels for the various components/traces/whatever).
> This is what I think goes wrong:
> HtmlHeaderContainer throws an exception while rendering, or something, such that its onDetach() is never called on it. This causes the reference it has to headerResponse to never be set to null. It therefore has a ref to a HeaderResponse, which has a ref to the Response object itself.
> We need to fix it so that onDetach() is always called, I guess. Probably need to work out where to put the try {} finally {}, essentially.
