MiLight Bridge: change name of things not possible (will not save)

fresh openHABian 2.1 stable installation:

I am having trouble with adding ‘things’ from my Milight Bridge. When adding Milights (RGB) from the inbox as ‘Things’ I can change the name but not the location. When the added item is a thing I can click edit and change the name and location but when I am clicking the save button it does nothing.

When I look into the console of the browser I get:

Error: groups is undefined 
setConfigDefaults@http://192.168.1.196:8080/paperui/js/services.min.js:1:31186 $scope.update@http://192.168.1.196:8080/paperui/js/controllers.min.js:1:30102
<Rest deleted because a new user can post max 2 links in a post...>

With other ‘things’, unrelated to the Milight bridge I can change the name and location without any problem.

Please don’t post useless links at all. Use code fences for pasting of code and/or logs:

Use three Backticks in a row or use the button in discourse’s editor to do this for you :wink: (the second from right)

Please don’t forget to give additional information: How did you install (manual, apt-get, openHABian)? Which version? OH2.1 (stable) or OH2.2 (snapshot)? In case of the latter: Which version exactly? (Build number)

I’m not certain but I think this has been fixed in 2.2, which was just released.
