Ionic Deep linker view does not update on browser back button event - ionic2

Question

I have a PWA built with ionic deep linker. I have done a demo here https://stackblitz.com/edit/ionic-mee2ut?file=app%2Fcustomer%2Fcustomer.component.html where the browser back button doesn't work as expected.
Steps to reproduce
1.In Dashboard page click on edit button.It will navigate to customer
page(see URL.It is changed to /Customer/CustomerId).
2.In Customer page, you will see the customer info and other customers
list, there click edit from other customers list.This will open another
page.(see URL.It is changed to /Customer/CustomerId).
3.Click on browser back button u can see that the URL is changed but the
view is not updated.
If I repeat steps 1 & 2 then click on nav back button instead of browser button then it works correctly.Both the URL and the view gets updated.
Is there something I am doing wrong because the browser back button does not work as expected or this is issue of ionic framework.
This is how i navigate between views
EditCustomer(Customer: any) {
this.navCtrl.push('Customer', { Id: Customer.Id, Name: Customer.Name });
}
Can somebody please tell me a way how to resolve this issue?

Answer 1

I saw your code in the above url, you are passing id as param but not the name so, that is the reason url is changing but data is not reflected i modified your code in app.module.ts file please replace this code in your app.module.ts file
IonicModule.forRoot(MyApp, {}, {
links: [
{ component: DashboardComponent, name: 'Dashboard', segment: 'Dashboard' },
{ component: CustomerComponent, name: 'Customer', segment: 'Customer/:Id/:Name' }
]
})

Please replace your app.module.ts with the following code
import { Component } from '#angular/core';
import { Platform, IonicApp, App } from 'ionic-angular';
#Component({
templateUrl: 'app.html'
})
export class MyApp {
rootPage:any = 'Dashboard';
constructor(private _app: App, platform: Platform, private _ionicApp: IonicApp,) {
platform.ready().then(() => {
this.setupBackButtonBehavior();
});
}
private setupBackButtonBehavior () {
// If on web version (browser)
if (window.location.protocol !== "file:") {
// Register browser back button action(s)
window.onpopstate = (evt) => {
//Navigate back
if (this._app.getRootNav().canGoBack())
this._app.getRootNav().pop();
};
}
}
}

I was able to use something like this:
let randomID = this.makeId(5); // random string id
this.navCtrl.push('path', {
eventID: eventID,
instituteID: instituteID,
randomID: randomID
}, {
id: `path/${eventID}/${instituteID}/${randomID}`
});
This "id" seems to fix it, but if you can go to the same page, then it requires a "random" value to separate each visit to that page.
#IonicPage({
name: 'path',
segment: 'path/:instituteID/:eventID/:randomID'
})
It looks like, by default, it uses the name of the page as an id for that view. If multiple views have same id => issue when using browser back/forward. That's where the random comes in, to separate multiple instances of the same page.
