The problem appears with the following HTML-code:
with autolinking set to true like this:
This leads to the following exception:
org.apache.wicket.markup.MarkupException: Unable to find component with id 'top' in [WebMarkupContainer [Component id = _autolink_-335431082]] Expected: 'autolink-335431082:top'.
This happens since the the fix of
WICKET-6289. The bugfix in this issue was to create a WebMarkupContainer as default autocomponent. It was and ExternalLink before, which didn't cause any trouble in this case.
But is it really correct that AutoLinkResolver even tries to replace an anchor link?
I also created a quickstart project to reproduce the problem:
