import { NgModule, Component } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { CoreModule, AlfrescoSettingsService, AlfrescoAuthenticationService } from 'ng2-alfresco-core';
import { DiagramsModule } from 'ng2-activiti-diagrams';

@Component({
    selector: 'activiti-diagrams-demo',
    template: `<activiti-diagram [processDefinitionId]="'HealthCareExpressVisitationLog:10:27642'"></activiti-diagram>`
})

export class DiagramDemoComponent {

    constructor(private authService: AlfrescoAuthenticationService, private settingsService: AlfrescoSettingsService) {
        settingsService.bpmHost = 'http://localhost:9999';

        this.authService.login('admin', 'admin').subscribe(
            ticket => {
