Yes, ok. But I use wicket for hobby, it is not my daily work. I already use Label, but for write text into the page. The Models in wicket is still a misterius for me, I read books, docs, but I still not undenstand models, so I use it just as I see on docs, but I don't know how it works exatly. If you can help me, I will appreciate a lot.
