Menu language Undefined when it inherits language from node

Maybe the actual bug is 'why the menu item doesn't get the node language?', not fixing it later.

I was having the same problem and it was driving me nuts for sometime. Then I noticed that if I change the content language to "Language neutral", then save and then edit and change to the correct language and save again, the menu language gets fixed. Good that I don't have to apply a patch!

In fact, this issue is caused by a misconfiguration of the menu settings in a content type.
If you manually added a menu link pointing to a node in a menu that is not enabled for this content type, then it will fail to get the menu item language.

To fix it, just edit the content type and add the menu in the available menus. Then if you save content again, menu item language will be correct.

I think the reason is well explained by @jide in #7

About the patch, it won't work for new menu items created. This should be done when creating/updating new menu items, not in the form.

If you manually added a menu link pointing to a node in a menu that is not enabled for this content type, then it will fail to get the menu item language.

To fix it, just edit the content type and add the menu in the available menus. Then if you save content again, menu item language will be correct.

No. In my case, the menu is enabled for the correct content types, and when I change something, export the feature and revert it on another site, all the links lose language information, and become "Undefined". Just like that.

Not even with the patch in #3 this is working for me.

Edit: Please, ignore. It appears this problem is with the Features module:
http://drupal.org/project/issues/features?text=menu+language

note: see also #1642344: i18n_menu 6.x -> 7.x upgrade path

To fix it, just edit the content type and add the menu in the available menus. Then if you save content again, menu item language will be correct.

I had all items for both languages (English and Italian) showing at the same time. For others encountering this, here is what worked for me:

1. The content type in question: Go to edit screen (admin/structure/types/manage/CONTENT_TYPE) -> Multilingual Settings ->select Require language (Do not allow Language Neutral).
2. The menu in question: enable all links (in my case both English and Italian)
3. Click on each page in the menu one-by-one, go to the Edit page for the item (click the Edit tab at the top). Simply click save at the bottom.
4. Done.

3: 1594804-menu_node_language.patch queued for re-testing.

For all I've read, it seems this was caused by some misconfiguration.

Also the patch just fixes how it is displayed on the form, which may confuse more than help (you are seeing different values from what it's stored in the database).

Feel free to add this to the module's handbook, but we don't really need this patch.

otra opción cuando se edita un link del menu es: momentáneamente copiar la ruta del nodo y cambiar la ruta del path por o guardarlo, al volver a editar el Link, si permitirá seleccionar el idioma que queremos para el nodo, restaurar la ruta de nuestro nodo en el path, guardar, y luego traducir....
===================================================================
(translate with google)temporarily copy the path node and change the path by or < nolink > save it, to re-edit the link, if you to select the language, you want for the node, restore the path of our node, save , and then translate ....

This is a real, reproducible issue:

When creating a menu link from admin/structure/menu/manage/{menu}/add :

1. You can set the language while creating, but you can't change it.
2. There is nothing in 18n_menu to ensure that the language is set correctly.

I can forget to set language, or set incorrect language. After that I see the message "This menu item belongs to a node, so it will have the same language as the node and cannot be localized." - which is misleading as it may not have the same language as the node, and I can't fix it.

If we are disallowing setting of language, there must be something that automatically sets correct language.

Trying to fix it by setting language on menu link save.

Rerolled #17 for dev. Tested working.

adding some tests for php 5.4 , 5.5, and php 7

So no reported regressions from patch #18 ?

is it possible for someone to write a simpletest for this?

Rerolled #18 aganist 7.x-1.26, just couple offsets.
