OK, I found out that it is not working if the file (reading_list.org) is not opened in the buffer. If opened then it works all right.

I guess it should be working like that.

Hi,
when I try to do this:

#+COLUMNS: %28AUTHOR(Author) %32ITEM(Name) %TODO %TAGS(Tags) %CLOSED(Closed) %STARTED(Started)

#+BEGIN: columnview :id "file:~/Org/reading_list.org"

#+END:

I'm getting wrong type argument stringp nil error. Filepath is good otherwise some different error is popping and columnview is working in that file. Do you know what can be wrong?
