"Encountered an error in Angular: ContentChild not found

Working with Angular 5, I am attempting to develop a dynamic component.

One of the components is a simple directive named MyColumnDef (with the selector [myColumnDef]). It is used in the following:

parent.compontent.html:

<div>
  <my-table>
    <ng-template myColumnDef>
      Lorem ipsum.
    </ng-template>
  </my-table>
</div>

my-table.component.html:

<div>
  Something:
  <ng-container *ngTemplateOutlet="temp"></ng-container>
</div>

In my-table.component.ts:

 @ContentChild(MyColumnDef, {read: TemplateRef}) temp;

The expected output should display the text 'Lorem ipsum.', however, the temp variable is actually undefined (as indicated by the console.log in ngAfterViewInit) and the reason for this remains unclear. Could there be something that I have overlooked?

Answer №1

My mistake was not including the directive in a separate module's exports array.
