[4.0.0-beta.7] Relative routing does not work after returning to same page

[doender]

When I use relative routing to go from page A to page B like so:

openPageB(id) {
   this.router.navigate(['b', id], { relativeTo: this.route });
}

and then go back to page A (via the browser back button or an ion-back-button), calling openPageB again does nothing. When I use absolute routes everything works normally.

I've created a repository to demonstrate the issue here: https://github.com/doender/routingError

@mhartington this has been moved from the forum to github as you asked. Do you have some new info about this? You said it was incorrect the way we were navigating, but can't catch the error, this must be a bug in ionic 4.

Seeing this as well, using both Angular's Router directly as well as using NavigationController. @giacomocerquone Can you provide a link to the post in the forums?

EDIT: Seems this is the post

Relative routing is not something that is going to be supported. I added a note in our new navigation docs.

@biesbjerg yes that is the post (see below for a good solution)

@mhartington really sad. I suppose this decision has been taken since it isn't a problem easy to tackle since the bug has been tracked down in angular.

There is this other issue I opened to collect all the others and tivomaker gave a wonderful solution #15959 have a look
If not supported, at least let's add in a recipe section, or wherever you want, that code.
And some support should be given to the users in order to give them a solution because as it is, it's really problematic... it's more a bug than a missing feature
