ReactMount: Root element has been removed from its original container. New container

After this I get this:

When I get those problems I'm trying to update my view with a new list of items. To update my current view I call updatePosts():

var updatePosts = function () {
    var content = document.querySelector('.content');
    content.innerHTML = '';
    $refresh.addClass('fa-spin');
    return React.renderComponent(
        <Posts />,
        content
    );
};

Can be this innerHTML = '' the problem? I'll render my Posts component entire again.

Answer 1

Remove this line

content.innerHTML = '';

React will look at the old virtual dom, and what's returned by <Posts /> (which is the same as Posts()). It'll compare them, and make the updates required to the DOM.
