Angular2 router 2.0.0 not reloading components when same url loaded with different parameters?

by

update 2

This answer is only for a long ago discontinued router version.

See https://angular.io/api/router/RouteReuseStrategy for how to do it in the current router.

update 1

That’s now fixed (Angular 2.3) for the new router by https://github.com/angular/angular/pull/13124 which allows to provide a custom reuse strategy.

For an example see also https://www.softwarearchitekt.at/post/2016/12/02/sticky-routes-in-angular-2-3-with-routereusestrategy.aspx

That’s a known issue.
Currently there is no way to make the router re-create the component on parameter-only route changes.

They discussed plans to implement some reuse-strategies eventually.

You can subscribe to params changes and execute your code there instead of in ngOnInit()
