[support] Multilingual nodes in translated taxonomies

I have a web page in 3 languages. It's a library, the main node it's a book.

I have some taxonomies, for example the book category, tranlated to the three languages. I'm using i18n module.

I don't want to translate the book node (only the name of fields is translated with t() function).

The problem is if i put a book in a english taxonomy it doen't show in any of the translated taxonomies.

For example: I have the Book: "El Quijote" and the category: en "Novel" es "Novela" ca "Novela"

If i put the book in the Novel taxonomy it doesn't show in the Novela taxonimies (in spanish and catalan)

How can i solve this?

thanks in advance,
