>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket
>    Affects Versions: 7.5.0

> Auto components provided fail to render in certain cases due to changes in 
> https://issues.apache.org/jira/browse/WICKET-6231.
> See attached quickstart.
> Debugging reveals that this is caused by the change to 
> {{Component#getMarkup()}}. The markup that is set for auto-components might 
> not have the same variation as the html file in which it is used. Because of 
> this, the new {{markupHasCurrentVariation()}} returns {{false}}, and we fall 
> through to the end of {{getMarkup()}}. As the auto-component is dynamically 
> added on each render, {{parent.getMarkup(this)}} returns {{null}} - the 
> markup id gets created on the fly by component resolvers.
> In other words: if you use a component resolver in a page which overrides 
> {{getVariation()}}, but the html file for that page is the "default" one 
> (without the variation in the filename), wicket throws an RTE 
> (MarkupNotFoundException: Markup not found for Component: [WebMarkupContainer 
> [Component id = custom0]]).
