Another try to do what I want: I tried completion-table-dynamic with something like the code below. This also fails, but now because when showing the completions there seems to be a requirement that the minibuffer contents matches the alternative in another way then the completion-table-dynamic function did. This makes it rather unusable. Am I missing something here? Please run the function below and try to complete with the input Test selection: group TAB The message buffer will show that the return of completion-fun2 is ok, but there is no completion window. Am I missing something or is this a bug?
