Update button does't work in production enviroment

Hi There,

Problem, the update and copy function in a single form doesn’t work anymore. The form just works fine. i altered something and the after deploy it doesn’t work anymore (latest update)
The form has:
Show hide fields (depending on choice)
Nested grid
Nested form
Multiselect in it

I tried everything even make my own update button nm_atualiza(‘alterar’);. but the strange thing is when you press the button, nothing happens and no message of any error. also with debug on. In development all just works fine

Figuren IT out. Was An htlm field problem no error was schoen, but even i changed the field, everything worked
