React-redux-form: Object.keys: argument is not an Object (IE11)

[varzock]

The Problem

Validation on Internet Exploder (sic) 11 causes error: Object.keys: argument is not an Object

Steps to Reproduce

For example with LocalForm. Same problem occurs with Form as well. Create Form with validations object on the form. Focus on field, check console.log and you'll see the error message. OnChange triggers it.

Error seems to be caused by line 364 in form-actions-reducer.js.

Expected Behavior

No errors on IE11.

Actual Behavior

On Internet Explorer 11: Object.keys: argument is not an Object
Other browsers seem to be fine.

Reproducible Code Example

<LocalForm
    model="user"
    noValidate
    validators={{
        firstName: {
            isRequired: (value) => value && value.length,
        }
    }}
>
    <Control.text
        model=".firstName"
    />
</LocalForm>

Sorry, couldn't get the CodePen fork working.

@davidkpiano I'm still experiencing this same issue on IE11 after the 1.12.0 update. I'm seeing this with almost an identical config to the one above only on the

component rather than LocalForm.

Inputs are set up to validateOn="change" and there is a 300ms debounce as well.

The stack trace points to the updateParentsForms function. I can try to put together some more detailed tests later.

Update: I did some more digging here. For whatever reason I had decided that I only need to have es5-shim and es7-shim installed. It looks like adding es6-shim to the mix fixed this issue.

Thanks @hitchcockwill I was running into the same issue using a combination of 'create-react-app' and had to simply add es6-shim to the polyfills.
