I don't know why, but I remembered that when you have a symfony form with required fields not rendered, the isValid function do not check for them.
I mean it only check if the widget got a value when you use it. And it seem in my current project that it is wrong.
Is there a setting or something allowing to do this ?
Edit : Here is the form :

Edit 2 :
The question is : is it normal than the DEMANDE_DTDEM field required, raise a required form field error, whereas he hadn't been rendered ?
Shouldn't a form field be validated only when he was used ?
Yes, it's the normal behaviour. Fields VALIDATION has nothing to do with rendering. If you don't want to render a widget you must explicitly remove both widget and validator (with unset or useFields).
If you define a widget and a validator (like in your case), but you don't call to $form['DTDEM']->render(), the value will be always empty.
IT'S VERY IMPORTANT THAT YOU UNDERSTAND THAT. In this case, the field is required, and then become that error, but if it wasn't required, the $form->save() method will always clean the value of the object in your database!
NEVER leave the widgets unrendered. You should do some echo $form while debugging to see what widgets are configured, and if you don't want some of them, just remove them in the form configure() method (as I said, with unset or useField)
