Burger-menu dissapears when using setRoot to change page

Hello,

I added a burger menu to my project and I would like to see it on every page I visit, but it disapears.

I tried to make a clear example of the problem:

  1. made a new project
  2. created 2 pages: page1 and page2
  3. created 1 component: switch-page

page1 and page2.html looks like:

<ion-header>
  <ion-navbar>
    <ion-title>Page 2</ion-title>
    <button ion-button menuToggle>
      <ion-icon name="menu"></ion-icon>
    </button>
  </ion-navbar>
</ion-header>
<ion-menu [content]="content2">
<ion-content>
    hello
</ion-content>
</ion-menu>
<ion-nav #content2></ion-nav>
<ion-content padding>
  this is page 2
  <switch-page selectedPage="Page2"></switch-page>
</ion-content>

the switch page component is really simple:

<button type="button" (click)="activePage()">switch page</button>

import { Component, Input } from '@angular/core';
import { NavController, NavParams, LoadingController } from 'ionic-angular';
import { Page1Page } from '../../pages/page1/page1';
import { Page2Page } from '../../pages/page2/page2';

@Component({
  selector: 'switch-page',
  templateUrl: 'switch-page.html'
})
export class SwitchPageComponent {

  text: string;
  @Input() selectedPage: string;

  constructor(public navCtrl: NavController,
    public navParams: NavParams,
    public loading: LoadingController) {
  }

  public activePage(): Promise<void> {
    let loader = this.loading.create();
    loader.present();
    if (this.selectedPage === "Page2") {
      return this.navCtrl.setRoot(Page1Page).then(() => loader.dismiss());
    }
    else {
      return this.navCtrl.setRoot(Page2Page).then(() => {
        loader.dismiss()
        console.log(this.navCtrl.getActive())
      });
    }
  }
}

As you can see in the gif, the burger menu disapears when I setRoot… How to fix that ?
I’m searching the web since yesterday and I think I’ve read every topic about menuToggle on ionic forum without finding a solution to my problem.
Thank you. I can send source code if needed but I don’t think it’s necessary as there is almost no code !

if you can’t see the gif, i can send a video

I forgot to mention that I’m using Ionic 3 and angular 4, this might be a bug. Should I open an issue on Github?

I’m not sure that this design is the clearest way to deal with navigation, but that aside, have you read the section about persistence in the Menu docs?

Hello,
I tried, but it has no apparent effect.
I read on the doc: "Persistent menus display the MenuToggle button in the Navbar on all pages in the navigation stack."
I think that persistent menu is only for “pushed” pages…

Should I open an issue github ?
