This appears to be the same issue as bug #31309

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=31309


At present in wid-edit.el we see:

(define-widget 'group 'default
  [...]
  :format "%v"

And that format of "%v" is triggering the error.

In #31309 I noted that:

> the parent `editable-field' widget says:
> "Note: In an ‘editable-field’ widget, the ‘%v’ escape must be preceded
> by some other text in the ‘:format’ string (if specified)."

And so I copied the :format "%{%t%}: %v" used by the 'string type.

If we make that same change here:

(define-widget 'group 'default
  [...]
  :format "%{%t%}: %v"

Then the example code from this new bug works.


Possibly there are other such bugs here as well?

8 matches for ":format "%v"" in buffer: wid-edit.el
    594:  :type '(repeat (cons :format "%v"
    597:			       (string :format "%v")))))
   1870:  :format "%v"
   2214:  :format "%v"
   2392:  :format "%v"
   2749:  :format "%v"
   2905:  :format "%v"
   3565:				(cons :format "%v"
