Hello!
Well, you can override a component, you can decorate or advise the
ComponentClassResolver service. Specifically, when
the resolveComponentTypeToClassName(String componentType) method is called,
if componentType.equalsIgnoreCase("GridColumns"), then return the fully
qualified class name of your GridColumns replacement component. Otherwise,
let it return normally. That's basically how ComponentSubstitutor is
implemented inside Tapestry itself.
Just curious: what customizations do you want to do?
