1. Why ListPageModule isn't declared in https://github.com/driftyco/ionic2-starter-sidemenu/blob/3/src/app/app.module.ts and works without an issue?
2. Why it doesn't work when it's declared?

Error I am getting:
TypeError: undefined is not a function

Hello @maitbayev , would you mind posting an example of your issue please? I think i understand the issue here, but I would love if you could show an example.

[maitbayev]

Generate SideMenu template from branch 3.0. Modify src/app/app.module.ts to reflect changes below and run "ionic serve".

@jgw96 Feel free to clarify.

import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';

import { MyApp } from './app.component';
import { HomePageModule } from '../pages/home/home.module';
*****import { ListPageModule } from '../pages/list/list.module';*****

import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

@NgModule({
  declarations: [
    MyApp
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
    HomePageModule,
    *****ListPageModule*****
  ],
  bootstrap: [IonicApp],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

Oops, its updated. Seems like to lazy load we shouldn't declare. We need to declare if the component is loaded. Thanks

[peterpeterparker]

@maitbayev what what what? I've got the same error right now, could you elaborate a bit?

[maitbayev]

@peterpeterparker are you adding your generated modules to "imports" in app.module.ts and trying to navigate with string name?

[peterpeterparker]

@maitbayev yep, I only import one module in import (the first page of the app) and I converted all my push, setRoot and modal.create to use string names

[maitbayev]

@peterpeterparker I think the first page should not use a string name. See: ionic-team/ionic2-starter-sidemenu@818d0ed

[peterpeterparker]

@maitbayev I think you are right but I don't understand why it's working in the conference-app (see https://github.com/driftyco/ionic-conference-app/blob/lazy-load/src/app/app.component.ts)

anyway that didn't solve my issue :( I've got the feeling I may have some problems with the loading of the child-/sub-components

[peterpeterparker]

I opened a new issue because I was unable to solve it
