>
> Key: WICKET-188
> URL: http://issues.apache.org/jira/browse/WICKET-188
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.2.4, 1.2.3
> Environment: Tomcat 5.5.20, jdk 1.5.0_09, wicket 1.2.4
> Reporter: Robert Novotny
> Assigned To: Igor Vaynberg
> Fix For: 1.2.5, 1.3, 2.0
>
> Attachments: AbstractBehavior-patched.java, sample-project.zip
>
>
> The header contributions seem to be appearing and disappearing randomly. Let
> us have a simple webpage containing a link and a StringContributor. If I
> click on the link, the page refreshes and contributions appear normally.
> However, in the subsequent refreshes of that page in the browser (using the
> browser's refresh button) the contributions are not appearing.
> There was already some fix in the HeaderContribution issue in Wicket 1.2.3.
> Does this problem have something in common with the fixed HeaderContribution
> issue in the Wicket 1.2.3? This problem does not occur with Wicket 1.2.1.
> After a little bit of debugging, I am suspecting that the ,,entries" Set in
> the AbstractHeaderContributor is not properly cleaned up between the requests.
> I have tried to blindly patch the AbstractBehavior according to the latest
> version in the trunk (there is some additional cleanup in this latest
> version) and this seems to have solved the problem (however I am not sure,
> whether this is sufficient).
