## Basic usage

### Activiti Process Instance List

This component renders a list containing all the process instances matched by the filter specified.

```html
<activiti-process-instance-list [filter]="processFilterModel"></activiti-tasklist>
```

Usage example of this component :

**main.ts**
```ts

import { NgModule, Component } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { FilterRepresentationModel } from 'ng2-activiti-tasklist';
import { CoreModule } from 'ng2-alfresco-core';
import { ActivitiProcessListModule } from 'ng2-activiti-processlist';
import { AlfrescoAuthenticationService, AlfrescoSettingsService } from 'ng2-alfresco-core';
import { ObjectDataTableAdapter, DataSorting } from 'ng2-alfresco-datatable';

@Component({
    selector: 'alfresco-app-demo',
    template: `<activiti-process-instance-list [filter]="filterRepresentationModel" [data]="dataProcesses"
             #activitiprocesslist></activiti-process-instance-list>`
})
class MyDemoApp {

    dataProcesses: ObjectDataTableAdapter;

    filterRepresentationModel: FilterRepresentationModel;

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

        this.authService.login('admin', 'admin').subscribe(
            ticket => {
                console.log(ticket);
            },
            error => {
                console.log(error);
            });

        this.dataProcesses = new ObjectDataTableAdapter([], [
                {type: 'text', key: 'name', title: 'Name', cssClass: 'full-width name-column', sortable: true},
                {type: 'text', key: 'started', title: 'Started', cssClass: 'hidden', sortable: true}
            ]
        );
        this.dataProcesses.setSorting(new DataSorting('started', 'desc'));

        this.filterRepresentationModel = new FilterRepresentationModel({
            appId: '3003',
            filter: {
                processDefinitionKey: null,
                name: null,
                state: 'running',
                sort: 'created-desc'

        });
    }
}

@NgModule({
    imports: [
        BrowserModule,
        CoreModule.forRoot(),
        ActivitiProcessListModule
    ],
    declarations: [MyDemoApp],
    bootstrap: [MyDemoApp]
