The most sound advise I’ve heard regarding hiring developers, which I’d consider solid even outside the realm of Apache Wicket development:
Don’t hire Wicket programmers. Hire good OO programmers with real domain problem analysis skills. ? Jonathan Locke
Rather hired wicked programmers
I thought the following:
Wicket programmers=Good OO programmers with real domain analysis skills:)
However I guess you can mess up even good OO frameworks like wicket.
