Process Attachment List component	v2.0.0	Active	2019-01-14

Process Attachment List component

Displays documents attached to a specified process instance.

Basic Usage

<adf-process-attachment-list
    [processInstanceId]="YOUR_PROCESS_INSTANCE_ID"
    (attachmentClick)="YOUR_ATTACHMENT_CLICK_EMITTER_HANDLER">
</adf-process-attachment-list>

Make sure to override the UploadService with the ProcessUploadService

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

@Component({
    selector: 'my-custom-process-attachment',
    providers: [
        { provide: UploadService, useClass: ProcessUploadService }
    ]
})
export class MyCustomProcessAttachmentComponent {
    constructor() {}
}

Transclusions

Any content inside the <adf-process-attachment-list> element will be shown when the list is empty:

<adf-process-attachment-list ...>
    <div><!-- Custom empty list message goes here --></div>
</adf-process-attachment-list>

A default template will be used if you don't supply a custom one to override it:

How to Add Drag and Drop Functionality

You can wrap the attachment list with an Upload Drag Area component to let the user upload attachments to empty lists. When you do this, you can also supply a custom no content template (using <adf-empty-list>) to invite the user to add their attachments:

<adf-upload-drag-area
    [rootFolderId]="YOUR_PROCESS_ID"
    [showNotificationBar]="BOOLEAN">
    <adf-process-attachment-list  
        [processId]="YOUR_PROCESS_ID"
        (attachmentClick)="YOUR_HANDLER">
            <div adf-empty-list> //no content template
                <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>
            </div>
    </adf-process-attachment-list>
</adf-upload-drag-area>
