Gero,
I didn't delete it.
Are you talking about this ?
You need to keep the book id along the process.
So you need to add the book id in the action associated with add button.
When you clic on add button you should call this url
bookfileform.html?Bookid=#
Anothor solution, add a binder to book object and display the list of book
in BookFileForm.jsp.
