----------------------------------------
Summary: IFormValidator Skipped When Any Dependent Component is
Disabled in Wicket 10.x
Key: WICKET-7159
URL: https://issues.apache.org/jira/browse/WICKET-7159
Project: Wicket
Issue Type: Bug
Reporter: Miroslav Silhavy
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.
