Troubleshooting the Issue with Angular Material Dialog Imports

Hey there,

I'm trying to utilize the Angular Material dialog, but I'm encountering issues with the imports and I can't seem to figure out what's wrong.

I have an Angular Material module where I imported MatDialog, and I made sure to import it in app.module as well.

The error message I'm getting is: ERROR Error: Uncaught (in promise): Error: Type DialogFormComponent is part of the declarations of 2 modules: AppModule and ProduitsModule!

app.module

import { DialogFormComponent } from './produits/dialog-form/dialog-form.component';

@NgModule({
  declarations: [
    AppComponent,
    DialogFormComponent
  ],
  entryComponents: [DialogFormComponent],

Produits.ts

export class ProduitsComponent implements OnInit {

  public productArray: Produit[] = [];

  constructor(public dialog: MatDialog) { }

  ngOnInit() {
  }

  openDialog() {
    this.dialog.open(DialogFormComponent);
  }

}

Answer №1

After some investigation, I realized that the issue was with my produits.module file where the dialogFormComponent was declared. Once I removed it, everything started working smoothly again. Thank you for your assistance!
