Hi Janos,
I did what you advised me to do but got the following exception (in this
case I used a list of 3 entries with 3 fields):
Unexpected RuntimeException
WicketMessage: The component(s) below failed to render. A common problem is
that you have added a component in code but forgot to reference it in the
markup (thus the component will never be rendered).
1. [MarkupContainer [Component id = cell]]
2. [Component id = 1]
3. [Component id = 2]
4. [Component id = 3]
5. [Component id = 4]
6. [MarkupContainer [Component id = cell]]
7. [Component id = 1]
8. [Component id = 2]
9. [Component id = 3]
10. [Component id = 4]
Root cause:

I don't really know which component I am missing in the markup.
I would be very grateful if you could help me once again, please.
