I am sorry about that...
Web2py default behavior for list:reference or reference is a HTML Select
and option... This is ordered by the navigator base on the spelling of the
element... So when you edit your form if you want to maintain the
preexisting order (the one that were there when you select items and order
them with bsm) you need to set them in order in the select yourself...
Bsmselect use OL that is Ordered List instead of UL... But it consume a
standard select... So, as long as he get a select with the proper ordered
options he can recreate the prexisting order... That is what the js I show
you does...
ordered_values content the list:reference or the reference value that are a
simple python list... List are items of list are ordered not like python
dict that not preserve order... So I just get the value of the field that
is a list object and pass it to the javascript as a list object... then I
create option from that list in javascript like you could do in web2py with
helpers for instance or by generating html yourself...
Hope it helps.
