I need to create a validator for a PIN field in my application. The PIN must:
1) Be between 4 and 12 characters long
2) Contain 3 out of the 4 of these:
a) lowercase letter
b) uppercase letter
d) special character ! @ $ % ^ & * ( ) + ?
What type of Flex Validator would I need to use? Does anyone have an example of handling this type of validation?
You should be able to do this with a RegExValidator, as documented on this page:
