[jira] [Commented] (WICKET-4347) renderHead not called in an IAjaxCallDecorator that implements IComponentAwareHeaderContributor

["Thomas Götz (Commented JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-4347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13189155#comment-13189155 ] 

Thomas Götz commented on WICKET-4347:
-------------------------------------

The JavaDoc in IAjaxCallDecorator is not up to date:
"Ajax call decorators are potential contributors to the page header by implementing {@link IHeaderContributor}.", should read: {@link IComponentAwareHeaderContributor}.

> See quickstart, the JS ResourceReference is not included. Problem is in AbstractDefaultAjaxBehavior, line 93: ajaxCallDecorator is of type CancelEventIfNoAjaxDecorator, and my CallDecorator is it's delegate and thus not checked (if instanceof IComponentAwareHeaderContributor).
