Version/test date: 26.10.2017
User: roland

Action:
precondition: user is added to a lot of contexts

user -> grants -> select role -> select context the user is already added to -> "add" -> context is displayed in "add grants" -> "add grants" ->
Observation: context is not added , but error message is not visible, since it is displayed right above the form. -> User has to scroll up to read message

Expected result: user gets warning closer to actual entry field

as of version 1.2.2 messages are displayed as modal dialogs.

user has to "click away" the messages manually and messages even stay if logged in with other user -> this is painful
