Ionic 3 - LoadingController - Uncaught (in promise): false

Ionic Framework ionic-v3
1 
ionViewWillEnter() {
    let loading = loadingCtrl.create({
        content: 'Espere...'
    });
    loading.present();

    this.accountProvider.currentAccount()
        .then(account => {
            //do somethings 

            loading.dismiss(); <-- Uncaught (in promise): false
        });
}


ionViewWillEnter() {
    let loading = loadingCtrl.create({
        content: 'Espere...'
    });

    loading.present();

    this.accountProvider.currentAccount()
        .then(account => {
             //do somethings 

              setTimeout(() => {
                  loading.dismiss();
              }, 0); <--  work fine
        });
}

It’s a bug?

Regards!

You have oversimplified the problem away, I think. You don’t provide AccountService, so I mocked its currentAccount() method like so:

  currentAccount(): Promise<any> {
    return Promise.resolve({foo: 'bar'});
  }

…and threw your code into the HomePage of a stock tabs project, and it worked just fine.

Hi @rapropos

Thx for your answer.

again…

ionic poc blank --v2

put this code into home.ts and it’ll failed

import { Component } from '@angular/core';
import { NavController, LoadingController } from 'ionic-angular';

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

  constructor(
    public navCtrl: NavController,
    public loadingCtrl: LoadingController) {

  }

  ionViewWillEnter() {
    let loading = this.loadingCtrl.create({
      content: 'Espere...'
    });
    loading.present();

    this.currentAccount()
      .then(data => {

        loading.dismiss();
        /*setTimeout(() => {
            loading.dismiss();
        }, 0);*/

      });
  }

  currentAccount(): Promise<any> {
    return Promise.resolve({ foo: 'bar' });
  }

}

It did not fail. It worked as expected.

Thank you for being persistent and nailing down that it might be version related. I made a new scratch project and was able to reproduce. Filed a PR to warn about this in the docs.
