Re: AW: [Wicket-develop] remove final from Cell

LOL. You're right ofcourse. And Jonathan will agree with you for sure. BUT... I've had many times that I really wanted to extend something that the authors did not anticipate. Defensive, yes. A bit arrogant too, as it states that you know exacly in what ways your framework will be used, and that other opinions about this are probably bad ;)

I can live with the current situation. I'll start screaming (or write my components from scratch) when I really need to override something.

I haven't looked into detail to the Wicket core. However I do think that
Jonathan had specific extension points in his mind and a specific way to
build components. The use of final is imo the best way to look at that.
Every time that final is *NOT* used, is an extension point. I think we
should keep this alive to the best of our abilities, until such time we
can't find a better way other than removing the final to extend/improve the
core framework.
It is not just inconvenience, it is a new way of programming most of us are
not used to: defensive programming.

To be honest, I could agree with removing final from all components, even
though for some of them subclassing would not be the best use. Just in case
people do not agree with the framework builders (that's us here).

Wicket is a lot about subclassing Components and thus adding functionality. The whole component tree is set-up like that. In order to extend Cell's functionality, it is obvious to extend Cell. In my case I want alternating row colors of html table. I used HtmlTagModifier and AttributeModifier, but the most intuitiv and Wicket-like implementation is to subclass Cell.handleComponentTag(). But because Cell is final, I can

not do it.

To use 'Jonathan's way' Why do you want to override that tag?

I'd like to override Cell.handleComponentTag() in my application. Any objections against removing final from Cell?
