angular2 routing - Issue with building an Angular 2 RC router link with a route parameter -

i in reference angular 2 documentation rc router route parameters:

here mentioned in documentation constructing router link route parameter:

['herodetail', { id: hero.id }] // {id: 15} 

this supposed produce following link:

localhost:3000/hero/15 

i have following link:

<a [routerlink]="['/dashboard/messageconversation/', {otherid: getother(message).id}]"> 

and produces following link (notice semicolon query parameter instead of route parameter):

http://localhost:8080/dashboard/messageconversation;otherid=2 

here @routes definition:

{path: '/messageconversation/:otherid', component: messageconversationcomponent} 

can please tell me getting wrong?

it turns out proper way add route parameter (as opposed query parameter) pass parameter second element of array follows:

<a [routerlink]="['/dashboard/messageconversation', getother(message).id]">
