Can you describe the workflow.
How do you add BookFile to Book object ?
Workflow:
1. Books are loaded, the controller is BookController and BookManager gets
all books. (books.jsp)
2. I select a book and BookForm is loaded (with book info), controller is
BookFormController, command class is Book. (bookform.jsp)
3. I click de button "Files" and BookFileList is loaded, the controller is
BookFileController and there bookManager gets the book and then the set of
bookFiles which is returned as:
return new
ModelAndView().addObject("bookFileList",bookManager.get(book.getId()).getBookFiles());
so the list of files is displayed. (bookfiles.jsp)
4. When I click on a file, bookFileForm is displayed, the controller is
BookFileFormController and it has a different manager wich is
BookFileManager.(bookfileform.jsp) Here it's the problem, I can't get to
associate the file to the book because I don't know how to get the book
without an id. In this controller I only have the id of the bookFile. So,
answering you second question, I can't add BookFile to the Book object.
