This error is straight forward - a parameter is usually deemed as "not provided" if it there either is no such field in the form or the input of the field is empty, while the parameter is defined as mandatory - which you did via the parameter definitions where you set the specific flag to "true". If you have filled out all the fields, then this error should not occur - if it still does, start analysing where the data may be dropped (or where you may have a typo) by checking the HTTP POST body of the form (use network view of the browser developer tools).

Ahh - I can imagine what the problem is. The values in the POST body look correct for your form configuration. But one thing that might trip the whole thing up is that you include an underscore in the names of your variable. The underscore is used in a semi-special way within the Alfresco forms engine / service - it is used to encode a colon character, which you will find in the fields for regular node properties (forms for documents / folders). So when mapping the key-values to parameters it may convert the first underscore (after prop_ is removed) into a colon, thus not matching your defined action parameters. I usually prefer using camel-cased parameter names over any that include non-alphanumeric characters.

Aaaaaargh , 3 days of my life for this bullshit , using the camelCase syntax it's all ok now.

Just for let it now even the "." give the same problem so in the end:

my_form_sign_firma.luogo WRONG

myFormSignFirma.luogo WRONG

myFormSignFirmaLuogo OK
