More support for translation of book pages

Yes, you're right. But with that point of view, BMS at all is an issue of the book.module.

So why not extend BMS to support this, as the said issue is an issue with (translating) books?

As long as you are not comfortable with I18n (Internationalization, 18 characters between I and n) you won't be able to understand my problem, I see. I will post a receipt so that you can follow my steps until you run into the same problem. But give me some time for this, please.
[Edit:]
Now, here is the receipt:

• Install the i18n module and activate Internationalization and Synchronize translation (I don't know if it is really needed)
• go to admin/settings/language and edit English. Here you enter "en" as path prefix
• now add another language (French?), but keep English as default
• now create two node types, one for book parent and one for child page. In section Workflow settings enable multilingual support with transalation. In subsection Synchronize translation you can check what you need. At first, keep all unchecked. In section BookMadeSimple I think you know what to do ;)
• Now make sure your current language is en. If not, add en/ in the url just before node/. Add content for a book parent in english and then add a child page in english, too (with BMS methods). The book outline should show the correct parent!
• You can enter additional book pages, if you want, but you need not to realize the said problem.
• Now translate the book parent into the other language (using the Translate-tab on the node view or node edit form)
• Now go back to original node (using the English link at the bottom), then to the book page. Translate this book page into the other language, too. Now, in the node edit form, check the Book outline section: no book is set! I would have expected to have the translated book there (all because it exists!).

What I lined out here, is what I think is the normal translation process: begin with the parent, then translate the child pages. And the translated child pages should stay connected within the translated book automatically.

Sorry, does not work correctly. The book is set, but the parent item is not.

If you add &parent=nnn to the url (or similar in the links array), where nnn is the bid of the translated parent, it should work. If I do it manually, it at least works.

Sorry, no changes, even with fresh drupal installation (except for trace messages still there).

[Edit1]
Now had some time to analyze the problem a little bit more. If you omit the parent item in a child page, it is replaced by the book itself, thus in the end, it seems to work. But if you translate a page on any lower level (a page as a child of a page), always the book itself is set as parent item. You can always control it before saving in the book outline section.

Could you catch/overwrite the function translation_node_overview in translation.pages.inc on line 15? This function lacks to create &parent=nnn in the generated link for add translation. Don't know if Drupal searches for a function book_made_simple_node_overview, in that you can clone and improve the code?

Both versions work for me! Thanks.

Great work!

Now, whats about a new release 6.x-2.1 or 6.x-2.x-dev?

To #13: Yes, it works!

Of course, I really like to do that! I have already written a small howto: Simple image gallery with imagefield where I mentioned BMS.

We can exchange e-mail adresse via the contact form. Then we can collaborate on the handbook until we have a final version.

I am also willing to write the german translation of BMS if you send me the .pot file.
