While this works as far as the autocomplete widget is concerned another
problem has arised:
I get an error: 'Value already in database or empty' when the widget is used
with crud when used in the following way:
The user has to enter a doc_nr where the history of generating the document
references are so complex that it not worth while to try and write code to
do that automatically. I want to use the autocomplete widget to show the
user what is already in the database as far as similar references are
concerned to enable him/her to type in a unique one. I know this is not the
usual usage of the autocomplete widget, and I can continue to use it with
SQLFORM.factory but would like to know whether I can bypass this problem
using CRUD.
