Github user scottyaslan commented on the issue: https://github.com/apache/nifi/pull/1205 The proposed changes look good and prevent the app from throwing an error when the user does not have permissions to read the remote process group. However, I noticed that the 'transmitting' and 'not-transmitting' classes are being applied even when the remote process group is 'invalid'. This is causing the warning icon fill color to be overridden to #728e9b instead of the #cf9f5d. Could you please add a check for invalid state when applying the 'transmitting' and 'not-transmitting' class?
