[TYPO3-mvc] Language property in fe_users

[Nils Blattner]

Hi everybody

I currently got a problem thats really annoying me no end.

I'm doing an alternate fe_users form in extbase/fluid and I'm trying to 
overwrite the 'language' field.
I started off with a relation to sys_language and now arrived at plain 
two-char languages (en, de etc).
However the data from the db never got as far as the php code/fluid template
After about 2 hours of messing around and contemplating why this doesn't 
work, I added a extkey prefix'd tx_..._language field and map'd it via TS.
For a second my {user.language} in the template actually showed 
something, but after saving it didn't work yet again.

So, my big question after seeing some newspost about language fields 
beeing bugged in extbase, would it help to rename the property in the 
model, or must I go search my code for another 2 hours?

Thanks for the help in advance

Nils
