Review Comment:
Hi @papegaaij, @martin-g I've pushed a fix to an older test. So that it does
not return null from getDependentFormComponents.

> Project: Wicket
> Issue Type: Bug
> Reporter: Miroslav Silhavy
> Priority: Major

> Regression causing a breaking behavior in Wicket 10, caused by change
> WICKET-3899. Discussed here
> [https://github.com/apache/wicket/pull/1033#discussion_r2104060257].
> Short description
> * After upgrading to Wicket 10.x, form validators ({{{}IFormValidator{}}})
> are not executed if any dependent form component is disabled, due to the
> addition of an {{isEnabledInHierarchy()}} check. This breaks backward
> compatibility for applications that rely on validators with conditionally
> enabled/disabled fields or a field with multiple radio buttons, as the
> validator is now skipped in these cases. This impacts forms with validation
> logic and causes migration issues for existing Wicket 9 applications. A flag
> or configuration to restore the previous behavior, or reverting the change,
> is needed for backward compatibility.
> * Common UI patterns with conditionally enabled/disabled fields no longer
> work with form validators
> * We must restructure validators and implement complex enabled/disabled
> field checking in {{getDependentFormComponents()}}
