but i think you have the basic idea right:
create a panel to represent each type of form component: textfield,dropdown, etc. these panels are just wrappers around the existing form components that do nothing more then provide markup for them.
create a panel to host these different panels based on some definition. this is the bean panel. it has a simple loop that inserts these panels and possibly wraps them with some border for consistent look and feel. this border can display label/errors/whatever.
so really the only markup you need for the entire form becomes <span wicket:id="bean-panel"></span>

Use case is
- to be able to generate lot of different forms (basically no grafic) with
fields which can be added removed dynamically
- maintain uniform look and feel (eg. not to define the html for
MyTextField on every form again and again - just define MyTextField.html
once and on form use add(new MyTextField("field1")) without need to add
<span wicket:id="field1"/> somewhere in form markup.
I could achieve this kind of behaviour with sligtly changed Loop and by
MyTextField extending Panel with added TextField. The problem is the panel
behaves only like wrapper without any real meaning and I can not override
easily TextField methods.
Basically I need to solve two things:
1. create component similar to loop without html markup, which renders its
children. Child does not have any tag (component does not have markup)
2. be able to provide markup for other components than panel (result of
point above) - eg. TextField
Thanx for any comments / hints
