Hi mboyle,
A possible solution would be to use custom validation rules defined as callback functions as the one for the Date validation in our demo. Then you may validate the fields depending on some custom Boolean flag defined outside the functions and used inside the validation functions. If the flag’s value is true, then implement your validation logic, if it is false, then always return true. Set the boolean flag before calling the “validate” function.
