ADF Upgrade from 6.8.0 to 7.0.0

[markknaus]

Hello, I am attempting to upgrade my custom ADF application from v6.8.0 to v7.0.0 and have been unsuccessful getting the 

DiagramComponent <adf-diagram> to be recognized. 

In the version ADF 6.8.0 app.module.ts file I would include ProcessDiagramComponent like this:

import { InsightsModule } from '@alfresco/adf-insights';

...

@NgModule({

    imports: [

            import  InsightsModule.forRoot()

...

declarations: [

           ProcessDiagramComponent

Here's the template implementation:

<adf-diagram [processInstanceId]="processInstanceId"

             (error)="diagramErr($event)"

             (success)="diagramSuccess($event)">

</adf-diagram>

After upgrading to ADF 7.0.0 it now tells me InsightsModule is deprecated and that 

ProcessDiagramComponent is not found.

Is the Diagram Component still available in version 7.0.0?

It looks like the cause of the adf-diagram component not displaying the process diagram is due to the model API is not invoked.

The ADF 6.8.0 version correctly displays the diagram after making the call to
http://localhost:4201/activiti-app/app/rest/process-instances/67501/model-json.
In ADF 7.0.0 the diagram is not displayed because there is NOT an API call made to
http://localhost:4201/activiti-app/app/rest/process-instances/67501/model-json.
