----------------------------------
Attachment: update_problem_ie6.zip
> AbstractAjaxTimerBehavior adds header-contribution to every ajax response
> -------------------------------------------------------------------------
>
> Key: WICKET-1405
> URL: https://issues.apache.org/jira/browse/WICKET-1405
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.1
> Reporter: Jani Väisänen
> Attachments: update_problem_ie6.zip
>
>
> The method renderHead in AbstractAjaxTimerBehavior calls super.renderHead
> (AbstractDefaultAjaxBehavior), which adds lines:
> - response.renderJavascriptReference(WicketEventReference.INSTANCE);
> - response.renderJavascriptReference(WicketAjaxReference.INSTANCE);
> to every response.
> This behavior causes at least usability problems in IE6.
> Selected components lose focus on every update even if it is not updated.
> If the page have a list which is updated on every second and a dropdown which
> isn't updated at all, user has to do his selection from the dropdown within
> that update interval. The dropdown list is closed on every update in IE6.
> This problem doesn't occur with wicket 1.2.6.
> Sample code: https://download.syncrontech.com/public/update_problem_ie6.zip
> Ajax debug:
