I've tried to add options to dropdown list with choice controller in nintex form using jquery, but when I tried to submit the form I've got this exception:
I understand what the problem is, but I couldn't find how to solve this, I mean how to disable Event validation, or how to register the new added options in the dropdown.
Any help will be appreciated.
