This wasn't expected to work, but I'm curious in how you tried to do it. :)

Contribute to the ComponentOverride distributed configuration, which is a
Map<Class, Class>, the key being the component or page or mixin class to be
replaced, the value being the replacement.
Here's an example from Tapestry's test suite:
@Contribute(ComponentReplacer.class)
public static void
overridePageAndComponentAndMixin(MappedConfiguration<Class, Class>
configuration) {
configuration.add(OverridenPage.class, OverridePage.class);
configuration.add(OverridenComponent.class, OverrideComponent.class);
configuration.add(OverridenMixin.class, OverrideMixin.class);
}
