reactjs - React-router universal. Why Root component does not re-renders? -

i have universal app (server rendering). routes.js looks this

routes.js

<route path="/" component={root}>   <route path="sales/:id" component={view} />   ... </route> 

--

root.js

class root extends component {   ...   render() {     return (       <div>         <header {...someprops} />         {this.props.children}       </div>     );   } } 

--

server.js

app.use((req, res) => {   match({ routes, location: req.url }, (error, redirectlocation, renderprops) => {     if (error) {       ...     } else if (redirectlocation) {       ...     } else if (renderprops) {       const initialstate = {};       const store = configurestore(initialstate);        fetchcomponentdata(store.dispatch, renderprops.components, renderprops.params).then(() => {          const html = rendertostring(            <provider store={store}>              <routercontext {...renderprops} />            </provider>          );          res.status(200).send(renderfullpage({ html, initialstate: store.getstate()}));       });     } else {       ...     }   }); }); 

my root , view components connected store (redux). works without server rendering , initial rendering on server works good. problem begins when trying change state , expect root component new props , re-render tree, in case root component not re-renders , view component re-renders.

i can't understand how can be? why part of tree static html?

update: have not found answer yet, assume root not giving new state. if why root component not connected store?
