I have not had time to fully diagnose, but when I run this locally I am losing the language context for the tags. I'll try to look into it further tonight.

Thanks @hernanvicente for doing this, I've never used that gem for tags so it's interesting to see how it works! I just left a couple of small comments

I'm having some troubles with this and I'm not sure if they're local to me or if the scope you're covering is different from what I'm expecting. Basically, adding a tag that doesn't exist is not working. If tags already exist for a language, I can add them using the select box but I cannot create a new tag for that language or for a language without tags.

Hello @dcollie2, to add new tags, the user must press ENTER. Maybe this necessary action isn't obvious or intuitive enough, so I added a hint (right to the label). Here is a short video. Let me know if you have further questions.

Hi Hernan. I was hitting enter and saving/updating the topic. When I do that, the new tags are not added. Let's diagnose during the call today. Since nobody else is seeing this, it's possible this is something local to my dev environment.
