don't work in which way =3F
Do you get an error , or just no selected options.

- if i assume you just get no selected options:

perhaps this could work =3F
tal:attributes=3D"selected python:item.idgrillasenales =3D=3D params['idgri=
llasenales']"

if i run into unexpected behaviour when doing comparizations like this
, i try to print both variables being compared in the value of the
select , so that it is simple to see the problem:

tal:attributes:value=3D"string:${item/idgrillasenales}/${params/idgrillasen=
ales}"


also make sure both items being compared are of the same type.. Much
frustration can be had by trying to compare integers and strings:

tal:attributes=3D"selected python:int(item.idgrillasenales) =3D=3D
int(params['idgrillasenales'])"
