Hi,
I need to do a validation of required fields who depends of the values of previos fields. More clearly, I have a radio button to choose between select by date or by docnumber. If the radiobutton selected is date, the date is required and the numdoc isn't and viceversa. With Validator I can check if a field is required but conditional validation I don't know how to do. I think it would be a common problem for many others developers. I would regard any help.
Thanks
Rodolfo
