thats funny, my primary usecase is to use link WITH a model. so why dont we keep Link generified and have a subclass VoidLink.
i am also not a big fan of using class hierarchy essentially as a typedef, seems like a nasty hack to me (which i am willing to live with). perhaps we can have wicket-void module that can contain all these Void subclasses. -igor On Sat, May 24, 2008 at 2:24 AM, Johan Compagner <[EMAIL PROTECTED]> wrote: > +1 > > On Sat, May 24, 2008 at 8:09 AM, Daniel Walmsley <[EMAIL PROTECTED]> wrote: >> >> Just to quickly weigh in on the verbosity argument: >> As someone who has coded Java (and Perl, C++, etc) in every environment >> from individual projects to multinational finance systems, I will say that >> verbosity of code runs a far, far, distant third (or twentieth) to: >> 1.
