Ok, I’m currently using Ionic 4.

I’m calling the controller as below,

```auto
  async onAdditionalEvidenceSelected({event}) {
    const popover = await this.popoverCtrl.create({
      component: "PopupMenu",
      ev: event,
      translucent: true
    });
    return await popover.present();
  }

```

I’ve created a component and imported the shared module in App, and the Page, neither work.

`import { PopupMenuComponentModule } from '../../components/popup-menu/popup-menu.module';`

It complains that it wants to be an entry component,

`Error: Uncaught (in promise): Error: No component factory found for PopupMenuPage. Did you add it to @NgModule.entryComponents?`

So I tried adding it as an entry component,

```auto
PopupMenuPageModule cannot be used as an entry component.
Error: PopupMenuPageModule cannot be used as an entry component.

```

I’ve read that it can’t be used as a component and must be an Ionic Page ([https://github.com/ionic-team/ionic/issues/11111](https://github.com/ionic-team/ionic/issues/11111)) but that won’t work either.

`import { PopupMenuPageModule } from './../popup-menu/popup-menu.module';`

I’m tearing out what little hair I have left, ha

Any help appreciated.

Thanks

Hi @Dunny!

The error message you received is really not helpful, but indicates that your Popover component is being loaded dynamically using a Component Factory under the hood, but things are not resolving correctly. The Ionic 4 documentation (as of the time of this post) doesn’t explain that **in order to get things working you’ll need to make the Angular Router aware of your component by adding it to the routing configuration**.

So, for your component, you’ll want to add something like the following, e.g., for a lazy loaded route:

```auto
const routes: Routes = [
	{
		path: '', 
		component: RootLazyLoadedPage,
		children: [
			{
				path: 'your-popover',
				component: PopMenuComponent
			},
		]
	}
];

```

Once you do that, the easiest way to create your popup is to use a direct reference to the `PopMenu` component rather than a string format, so you’ll want to change your example above to something like:

```auto
const popover = await this.popoverCtrl.create({
	component: PopupMenu,
	ev: event,
	translucent: true
});

```

Note the change from `"PopupMenu"` to `PopupMenu` (no quotes). That should get it working for you.

Hope this helps anyone else who’s been suffering from this documentation-related issue!
