Task Attachment List Component

Displays attached documents on a specified task.

Basic Usage

<adf-task-attachment-list 
    [taskId]="YOUR_TASK_ID" 
    (attachmentClick)="YOUR_HANDLER">
</adf-task-attachment-list>

If the List is empty, a default no content template is displayed.

How to Add Drag and Drop Functionality

If we want user to be able to upload attachments for empty lists, We can wrap our component with upload drag area component. In that case, We should also pass a custom no content template as shown below with our component urging the user to drag files to upload whenever the list is empty.

<adf-upload-drag-area
    [parentId]="YOUR_TASK_ID"
    [showNotificationBar]="BOOLEAN">
    <adf-task-attachment-list  
        [taskId]="YOUR_TASK_ID"
        (attachmentClick)="YOUR_HANDLER">
        <adf-empty-list>
            <div adf-empty-list-header>{{This List is empty}}</div>
            <div adf-empty-list-body>{{Drag and drop to upload}}</div>
            <div adf-empty-list-footer>
                <img [src]="Your custom image URL"></div> 
        </adf-empty-list>
    </adf-task-attachment-list>
</adf-upload-drag-area>

import { UploadService } from '@alfresco/adf-core'; import { TaskUploadService } from '@alfresco/adf-process-services';

Make sure to override the UploadService with the TaskUploadService

@Component({
    selector: 'my-custom-task-attachment',
    providers: [
        { provide: UploadService, useClass: TaskUploadService }
    ]
})
export class MyCustomTaskAttachmentComponent {
    constructor() {}
}

Upload Drag Area Component

If the List is empty, the custom no-content template we passed is displayed.
