You have to use the <ViewTitle> component inside your dashboard. But I agree with you that it should be documented, so I mark it as a (documentation) bug.
You are right, it works perfectly with a viewTitle.
Just for those who would be looking for how to do it :
```javascript
import React from 'react';
import {ViewTitle} from 'admin-on-rest/lib/mui';
import { Card, CardHeader, CardText } from 'material-ui/Card';
export default (props) => (
)
