One more comment on the subject.

 From what you write, and from what is in the manual, it suffices that 
"fields are surrounded by static text". However that is not enough.
The text may not be part of another widget. Even worse, in the 
programming example, this rule is broken! So if you run the example, you 
will see the "bug" i reported (click the Choose button).

The patch attached should correct these problems.

  Editable text fields are created by the @code{editable-field} widget.
  
! An editable field must be surrounded by static text on both sides, that

  @code{:format} keyword is useful for generating the static text; for
  instance, if you give it a value of @code{"Name: %v"}, the "Name: " part
  will count as the static text.
+ Observe that static text belonging to another widget does @emph{not}
+ count, however text inserted with @code{widget-insert} does.
  
  The editing text fields are highlighted with the
  @code{widget-field-face} face, making them easy to find.
