Redux-form get the value from other tab/component - forms

Question

I have to implement a form with a bit less than 30 different fields.
So I decided to split them in 2 differents container component with two tabs to navigate between them.
I use redux-form to handle the data binding.
For on component I can get the value from handleSubimit of one component. But the final validation must be in the last tab only. From here I only have access to the value of the second tab. Like the data from the store where wipe out.
How can I access the store where my previous data should be ?
TabNavigationBar.js
import React from 'react';
import TabNavigationItem from './TabNavigationItem';
const TabNavigationBar = ({ onTabChange, activeTab }) => {
const tabList = [
{ hasIcon: 'fas fa-user-circle', hastext: 'Information Utilisateur' },
{ hasIcon: 'fas fa-file-alt', hastext: 'Informations contrat' }
];
const clickOnTab = tabNumer => {
onTabChange(tabNumer);
};
return (
<div className="columns">
<div className="column is-offset-one-quarter-desktop is-offset-one-thirds-tablet is-half-desktop is-one-thirds-tablet">
<div className="tabs is-toggle is-fullwidth">
<ul>
{tabList.map((tab, i) => (
<TabNavigationItem
key={i}
tabSelected={() => clickOnTab(i)}
hasClass={activeTab === i ? 'is-active' : ''}
hasIcon={tab.hasIcon}
hasText={tab.hastext}
/>
))}
</ul>
</div>
</div>
</div>
);
};
export default TabNavigationBar;
UserForm.js
import React from 'react';
import { reduxForm } from 'redux-form';
import CiviliteRadioButton from './CiviliteRadioButton';
import NameInputs from './NameInputs';
import AddressInputs from './AddressInputs';
import MailAndDOB from './MailAndDOB';
import TelephoneInputs from './TelephoneInputs';
let UserForm = ({ handleSubmit }) => {
return (
<div>
<CiviliteRadioButton />
<NameInputs />
<AddressInputs />
<MailAndDOB />
<TelephoneInputs />
</div>
);
};
UserForm = reduxForm({
form: 'form1',
initialValues: {
user: {
adresse: {
country: 'France'
},
civilite: 'Madame'
}
}
})(UserForm);
export default UserForm;
ContractForm.js
import React from 'react';
import { reduxForm } from 'redux-form';
import InputItem from '../InputItem';
import ContratInputsList from './contratInputList';
let ContratForm = ({ handleSubmit }) => {
const submit = values => {
console.log(values);
};
return (
<div>
<div className="columns is-multiline ">
{ContratInputsList.map((item, i) => {
return (
<div className="column is-half" key={i}>
<InputItem spec={item.spec} />
</div>
);
})}
</div>
<div className="columns">
<div className="column">
<div className="field is-grouped is-grouped-right">
<input
className="button is-primary"
onClick={handleSubmit(submit)}
type="submit"
value="Envoyer"
/>
</div>
</div>
</div>
</div>
);
};
ContratForm = reduxForm({
form: 'form2'
})(ContratForm);
export default ContratForm;
EDIT
When I click on my tabs, redux-form/DESTROY is called and erase form1's data.

Answer 1

Try setting destroyOnUnmount flag to false in reduxForm(options).
