If I use multilingual Drupal setup and enable groups translation the group translated versions are not working.
For example you have three languages German, Spanish in addition to default English and you have Department group type with enabled translation and enabled group domain setting. The main domain is www.maindomain.com and you added a department with department1.maindomain.com subdomain. The department1.maindomain.com will show content of the group, but department1.maindomain.com/ge or department1.maindomain.com/es will show main domain content on the corresponding language.
Needs review
3.0
Code
Maybe setting the path_processor_inbound priority to something below language processing and above front page processing could help.
Thanks!
Here's a patch for 1.0.x including a language negotiator plugin. We can include that in 3.0.x as well.
