Error pages for HeaderContributor errors are broken
---------------------------------------------------
Key: WICKET-278
URL: https://issues.apache.org/jira/browse/WICKET-278
Project: Wicket
Issue Type: Bug
Affects Versions: 1.3
Reporter: Alastair Maw
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.
