Bean properties from view?
I have knowledgde of Servlets, JSP and JSF, and reading a bit about Wicket.
Something that turns me immediately off is that you have to use something
like
add(new Label("firstName", person.getName()));
add(new Label("lastName", person.getName()));
add(new Label("address", person.getAdress()));
add(new Label("postalcode", person.getPostalcode()));
etc....
to send data to the view. Which is a lot of hardcoded duplicated property
mapping code.
Isn't it possible to just send the whole person object to the view, just
like in JSP, JSF, Facelets? Instead of manally putting all person bean using
the add-method.

Yes - the part that you're missing is the Modal usage in Wicket and
particulalry, the way that components can work their way up their
hierarchy. See
http://cwiki.apache.org/WICKET/working-with-wicket-models.html#WorkingwithWicketmodels-CompoundPropertyModels,
for example.

no it is not possible. in wicket the view is dumb, it contains no
knowledge or logic. if, for example, the person has first name and
last name and you wanted to output a full name you would have to do
the concatenation in java code, and the view would simply have <span
wicket:id="fullname"/> placeholder. in wicket everything is done in
java, not spread out between controller and view.
that said, if you use a compound property model you can shorten your example to:
add(new label("firstname"));
add(new label("lastname"));
and in the view
<span wicket:id="firstname"/><span wicket:id="lastname"/>
