Thanks for the help, but I do'nt understand while the problem is the function. The form obtained from the function work very well so I think the function is ok. The only problem is the 'memory' of the already selected correct values for the SingleSelectField. All the other fields work well and the message of error is correctly displayed. The correct values are re-displayed but not the SingleSelectField's values.
Could be ther is something I do'nt understand in the validate engine. So, question: The @error_handler(activity1) line set the activity1 to be called in case of error. The function is really re-called with re-instantiation of all the variable and re-construction of the form? I think yes but have some dout while I do'nt understand how the message 'Missing value' wolud be displayed in a complete new instance of the form. And the pre-setted value after the error are re-displayed in the form if I do'nt re-initialize the parameters to pass to the form. So I think that depend from a browser cache. I did'nt find documentation about but if you can say me where I'm be happy to study ... Enrico Secco On 15 Giu, 10:32, "Diez B.
