1. Open emacs -Q, with Emacs from CVS from right now
2. M-x customize-variable RET whitespace-display-mappings RET
3. Imagine you want to change the $ (which represents newline) to / (or anything else) and do this change
4. Try to save changes for current session

  You get this error: "This field should contain a single character". And the change isn't saved.

  I don't attach the back trace because it's huge and doesn't add more information.


Thanks

  I left one step in between:

I think I fixed this. This was a wid-edit.el issue rather than a
whitespace.el one.

Reopened.

  * wid-edit.el (widget-specify-field, widget-field-value-get, character):
  Revert 2009-03-24 change, since it causes a more serious problem than
  the one it solves.  (Closes Bug#3136, reopens Bug#2689.)

I've committed a fix to trunk.  Thanks for the bug report.
