title: Pass multiple parameters to Router navigation in Angular
body: <p>I was able to pass a single parameter to Router navigate in Angular 4 like follow and it works fine.</p>
  <p><em><code>this.router.navigate(['modifyOrder/:labOrderNumber', {labOrderNumber: labOrderNumber}]);</code></em></p>
  <p>But when I tried to pass 2 parameters, it doesn't work.   It didn't take me to modifyOrder page but redirect me to the homepage without giving any error.</p>
  <pre><code>this.router.navigate(['modifyOrder/:labOrderNumber/:labInvoiceNumber', {labOrderNumber: labOrderNumber, labInvoiceNumber: labInvoiceNumber}]);
  </code></pre>
