title: How I can update array field value in redux-form?
body: <pre><code>isMain = (v, k) =&gt; {
  
      let {avatars: {fields}, push} = this.props;
  
      fields.getAll().map((avatar, key) =&gt; {
  
        fields.remove(key);
  
        push('avatars', {
          deleteImage: avatar.deleteImage || false,
          uuid: avatar.uuid,
          fileName: avatar.fileName,
          url: avatar.url,
          setMain: key === k,
        });
  
      });
  
  };
  </code></pre>
  
  <p>This is how I try^ 
  Doesn't work, I don't know why</p>
  
  <p>I use v6</p>
  
  <p>I also tried <strong>insert</strong></p>
  
  <p>But with <strong>insert</strong> field not removed only - copied! 
  Although the value of new fields changed</p>
