maxStringLength issue with null value

[duykhiem]

Hi,

In mostly "add new screen", object's properties will be null. Without input anything, the text field have null value should still satisfy all maxStringLength validation.

Current code : https://github.com/NewOldMax/react-form-validator-core/blob/master/src/ValidationRules.jsx#L55

Can we update it to something like this :

 maxStringLength: (value, length) => !isExisty (value)  || (validations.isString(value) && value.length <= length),

Thank you and Best regards, /K

Hi,

when you have null value in your input and change it to something else, React will throw warning like

is changing an uncontrolled input of type text to be controlled. Input elements should not switch from uncontrolled to controlled (or vice versa). Decide between using a controlled or uncontrolled input element for the lifetime of the component

so you must define some empty value for your input in any case to avoid this, because this library assumes that all inputs are controlled.

state = {
    defaultObject: {
        title: '',
        name: '',
    }
}
