not serializable exception

Hello,

After upgrading to wicket 6.21.0 I've get a strange serialization error
when adding the debug bar to ajax target. I do this on every ajax event in
development and it worked until today. The stacktrace extras:

Caused by: java.lang.RuntimeException: An error occurred while getting the
model object for Component: [Component id = data, page =
ro.emp.wicket.StandaloneHomePage, path =

Re: not serializable exception

Posted by Martin Grigorov <mg...@apache.org>.

Hi,

It seems to be caused by
https://github.com/apache/wicket/commit/562d43ccdd7f305f8ca641817f4b63a07ee8b6a6
As the commit message says this container should be removed before the end
of the request cycle, so it won't lead to such problem in the normal cases.
But combined with the DebugBar it breaks...
Please open a ticket. With a quickstart / test case would be perfect!
