Hi Carlo,
Look at the wicket interface wicket.model.IModel
public interface IModel<T> extends IDetachable {
public T getObject();
public void setObject(T value);
}
Every component in wicket has a default model. Think of the textfield
case where the model contains the string being entered. By layering or
using a specific implementation you can have the value of the text field
actually stored in a java bean.
Your "how is it loaded?" question is an implementation detail of the
particular model being used.
For example extending AbstractReadonlyModel would let you pull out a
specific field in a bean programatically.
Or you could use a CompountPropertyModel that does the same thing but
using some type of reflection.
Or a LoadableDetachableModel to pull in data from the database or other
non-serializable context that is reassociated on each request.
This page on the wicket wiki is a good entry point on this topic:

hi,
through what mechanism does it do it?
i was wondering if wicket uses reflection or it generates code on the fly
thanks

That's not entirely correct. Wicket uses the models to populate form
components

Yes, take a look at org.apache.wicket.util.lang.PropertyResolver

Is reflection used or does wicket use a library to do this?
I had a very slow experience when using Reflection, how does Wicket do
it?
Thanks
