I get the error "Wrong-type-argument: stringp, nil" when I try to start
Forms Mode with
M-x forms-find-file RET ~/Documents/test-forms.el RET
The backtrace is:
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
expand-file-name(nil)
find-file-noselect(nil)
forms-mode(t)
forms-find-file("~/Documents/test-forms.el")
funcall-interactively(forms-find-file "~/Documents/test-forms.el")
call-interactively(forms-find-file record nil)
command-execute(forms-find-file record)
execute-extended-command(nil "forms-find-file" nil)
funcall-interactively(execute-extended-command nil "forms-find-file" nil)
call-interactively(execute-extended-command nil nil)
command-execute(execute-extended-command)
My forms control file (~/Documents/test-forms.el) is as follows:
;; This demo visits ‘/etc/passwd’.
(setq forms-file "/etc/passwd")
(setq forms-number-of-fields 7)
(setq forms-read-only t) ; to make sure
(setq forms-field-sep ":")
;; Don’t allow multi-line fields.
(setq forms-multi-line nil)
(setq forms-format-list
(list
"====== /etc/passwd ======\n\n"
"User : " 1
" Uid: " 3
" Gid: " 4
"\n\n"
"Name : " 5
"\n\n"
"Home : " 6
"\n\n"
"Shell: " 7
"\n"))
which is copied directly from the example in the Forms manual
(info "(forms) Format Description"). And /etc/passwd exists and is
accessible from Emacs.
I get exactly the same error with all forms control files I've tried,
even something as seemingly simple as:
(setq forms-file "~/test-forms.dat")
(setq forms-number-of-fields 2)
(setq forms-format-list
(list
"Field1 : " 1
"Field2 : " 2
"\n"))
with a not yet existent data file.
Note: I checked Emacs 24.5 and I found I get the same error there.

Confirmed on Emacs 25.
This seems to be caused by the call ‘(set-visited-file-name nil)’ in
‘forms-mode’. Before that call, ‘forms-file’ is "/etc/passwd";
afterward, it is nil.

To clarify, the result is the same if you visit the control file via the
normal ‘find-file’ and invoke ‘M-x forms-mode’.
Also, I confirmed that commenting out ‘(set-visited-file-name nil)’
prevents the error, though that's unlikely to be the right fix on its
own.

I cannot reproduce this, neither with the 25.0.92 pretest nor with the
current emacs-25 branch. I tried both control files, and they both
worked (although I needed to change the file names a bit to adapt them
to my system's directory hierarchy).
Does this happen for you in "emacs -Q"?

Sorry, I don't see how this is related. According to the backtrace,
find-file-noselect is called with an argument of nil, and I don't
understand how this could happen, since the call I see:
;; find the data file
(setq forms--file-buffer (find-file-noselect forms-file))
invokes find-file-noselect with an argument that cannot be nil, and
has no relation to the visited-file's name.
There's another call to find-file-noselect, in
forms--intuit-from-file, but that one also uses forms-file, after
verifying that it exists (which is not the case in point):
;; Need a file to do this.
(if (not (file-exists-p forms-file))
(error "Need existing file or explicit `forms-number-of-fields'")
;; Visit the file and extract the first record.
(setq forms--file-buffer (find-file-noselect forms-file))
So I don't see how the problem could happen, and I definitely don't
understand how it is related to the set-visited-file-name call.
Does the problem happen to you in "emacs -Q"?
Thanks.

I tried this as well, and it didn't signal an error here.

No. I apologise for missing this. The problem does not occur for me with
`emacs -Q', neither in 25.0.92 nor 24.5.
I will bisect my init file and report back.
Thanks,
N.

The verdict is that, for me, the problem is caused by this Custom-set
variable:
'(major-mode (quote text-mode))

Hmm... I'm still not following. Can you tell how to modify your
recipe such that it will reproduce the problem in "emacs -Q"?
Thanks.

Thanks, I think I fixed this on the emacs-25 branch.

I can confirm that with your fix Forms Mode is now working with
customised major-mode. Thanks Eli (and John). Closing.
