Form submission: Cannot read property 'preventDefault' of undefined about react-material-ui-form-validator HOT 4 CLOSED

It happens when your value was null or undefined before changing.

state = {
    user: {}
};

<TextValidator
    value={user.email}    <------ first time user.email = undefined, so react thinks that is uncontrolled input
/>

And you can do something like this to avoid error

state = {
    user: {
        email: ''  <---- empty string by default
    }
};

<TextValidator
    value={user.email}    <------ works without warning
/>

Or something like value={user.email || ''}

Hi
As you can see, event already "prevented". If you want to use event for some purposes, I can add it to submit callback

Hi

Arrghh - I must have skipped over that - thanks for the swift reply, appreciated.

Last question, I also get the following warning:

Warning: TextField is changing an uncontrolled input of type text to be controlled.

Have you seen that? Not on submission, on change in a <TextValidator /> field

from react-material-ui-form-validator.

Can't thank you enough, only just started on React...it's good so far but sometimes a bit strange in it's warnings... thanks again, much appreciated
