Kamil commented on WICKET-6536:
-------------------------------
as far as I remember, I copied the source code, changed the line and it worked
as expected...
> Add generic to MarkupContainer#visitChildren

> Key: WICKET-6536
> URL: https://issues.apache.org/jira/browse/WICKET-6536
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 8.0.0-M8
> Reporter: Kamil
> Assignee: Sven Meier
> Priority: Major
>
> currently MarkupContainer#visitChildren has signature:
> {code:java}
> final <S extends Component, R> R visitChildren(final Class<?> clazz, final
> IVisitor<S, R> visitor){code}
> while im my opinion it should have:
> {code:java}
> final <S extends Component, R> R visitChildren(final Class<S> clazz, final
> IVisitor<S, R> visitor){code}
> Why force user to do class cast while we already know which class we pass to
> the method?
