React-router: How to reload the component while clicking a link?

[imWildCat]

I'm using react router to write a forum. The Route of topic page is like <Route name="topicShow" path="topic/:id" handler={TopicShowPage} />.
But if I visit topic/2 from topic/1, the component will not be reload? What's the best way to notify the component when a link is clicked?

// Im my topic component:
 componentWillMount: function () {
        var { id } = this.context.router.getCurrentParams();

        TopicNetworkingActions.getSingle(id, 1);
    },

The component doesn't need to be mounted again. Since it is already mounted on the page, it will use the same DOM elements. Try componentWillReceiveProps instead of componentWillMount, although I'm not sure if componentWIllReceiveProps gets called when the component is originally mounted.

I like to use componentWillReceiveProps:

componentWillReceiveProps: function (nextProps) {
     var id = nextProps.params.id;

     this.setState({
         topic: TopicNetworkingStore.getSingle(id)
    });
}

It prevents a re-render as stated in the docs: ReactJS Component Specs and Lifecycle
