TYPO3 Core

I can reproduce the bug too. (not to difficult). This feature is still in the core (checkout cvs=01/04/05).

While debugging (class.tslib_menu.php) this, it looks that the sys_language_uid is set to "0" somewhere (don't know) when there is no translation of the page.

How should this being solved? There where is is set to 0 when there is no translation (maybe a problem for the rest of the page/site), or somewhere in the class.tslib_menu.php?

Maybe I am wrong, please correct me (still a newbie)

I just upload a patch. Can somebody of the dev team check this of this is the correct way to solve this. I'll don't know if something will break if this patch is applied. On my site everyting is still working.

This should get fixed in 3.8 Will look at it.

The fix looks good and simple enough, and it works here, too. I don't see a reason why the language should be resetted other than on the current content. I will make a few more tests and commit this if nothing breaks.

I discussed this with Kasper, and he says it's not necessarily a bug. I'll see if this situation can be avoided with proper configuration but for now this is suspended until the BDFL says otherwise.

Okay, it seems like Kasper was right (as usual) when he said this is a config issue. Please try
config.sys_language_mode = content_fallback; 0
in your template setup and see if you get the desired result. It works for me...

O.K., I'll try the suggested solution and send my feedback.

This works with proper TS setup.
