My redux-form is reinitialized when switching language by changing react-intl wrapper props

I'm wrapping my app inside an IntlProvider from react-intl v2, like this:

<IntlProvider locale={this.props.lang} messages={this.props.messages}>

And I have my react-form forms down the tree. Everything is great.

But if I'm starting to fill up a form, and I decide to change the language of the UI (by listening to an action that will update my lang and messages props through my redux store), the form is being reset :-/

I see the action redux-form/INITIALIZE being fired when the lang changes.

And it happens even if I pass destroyOnUnmount: false to reduxForm().

It did not happen with uncontrolled form fields.

Any idea?

My code: App.js + Register form

Solution

  • Hmm... You are changing your initialValues prop, so it's initializing the form data. initialValues is intended to be used for canonical data from the server to be edited (e.g. a loaded record), not really for updating individual form values from outside the component.

    Perhaps you could use the plugin() API to notice the language change action (is that being changed via Redux?) and update the lang value in your form?
