ADF - get tasks-instances order By Id

[anakin59490]

Hi,

This is what i have done :

getActiveTasks (user): Promise<{}> {
  const listScriptPath = 'api/task-instances?authority=' + user +
    '&properties=wfvd_nomService,bpm_priority,bpm_status,bpm_dueDate,bpm_description&exclude=wcmwf:*&skipCount=0&maxItems=1000&';
  return this.apiService.getInstance().webScript
    .executeWebScript('GET', listScriptPath, this.scriptArgs, this.contextRoot, this.servicePath);
}

And this is what I get :


Is it possible to sort the results by id ?
I think i can use "orderBy" with "DESC" option in listScriptPath variable 
but i don't find the correct syntax

thank you in advance

Is this a custom endpoint? Why do you fetch tasks via the webscript and not via the proper REST api?

[anakin59490]

Because I have reproduced the project Share version that uses this way...

[anakin59490]

So this what I try :

alfrescoJsApi = require('alfresco-js-api');
....

getActiveTasks (user): Promise<{}> {

const requestTasks  = new this.alfrescoJsApi.activiti.TaskQueryRequestRepresentation();
return this.apiService.getInstance().activiti.taskApi.listTasks(requestTasks);

}

and I get the following error :

error TS2304: Cannot find name 'require'.

Is-it the rirght way to retrieve asks user and if it is, how can i solve this error ?

Thank you

That example is for the node.js. Are you trying to use it with the node or with the Angular?

[anakin59490]

Angular

[dvuika]

You can use one of the existing Angular services: alfresco-ng2-components/lib/core/services at master · Alfresco/alfresco-ng2-components · GitHub For example Alfresco JS Api gives you access to all the APIs: alfresco-ng2-components/alfresco-api.service.ts at master · Alfresco/alfresco-ng2-components · GitHu...

Thank you,

i have found a service:

this.apiService.getInstance().activiti.taskApi.listTasks(requestTasks);

requestTasks variable mut be TaskQueryRequestRepresentation type.

I have found this link that explain how to declare this type : adf-examples/ADF_2.0.0/javascript-api/angular2 at master · Alfresco/adf-examples · GitHub 

(.7  Call Process API)

const requestTasks = new this.alf.activiti.TaskQueryRequestRepresentation();

So i try to define it like this :

How to define requestTasks ?

[dvuika]

This is JavaScript and everything is dynamic You can create an object with JSON notation and cast it to any type if needed. The definition for IDE auto-completion is here: alfresco-js-api/index.d.ts at development · Alfresco/alfresco-js-api · GitHub 

So you can create an object like:

const request: any = {
  processInstanceId: 'value',
  text: 'value',
  otherProp: 'value'
}‍‍‍‍‍

Thank you, it's difficult for me to understand all the mechanism....

I get another problem when executing the instruction in my getActiveTasks method :

const requestTasks: any = {
  processInstanceId: 'value',
  text: 'value',
  otherProp: 'value'
};

// const requestTasks = this.apiService.getInstance().activiti.TaskRepresentation;
return this.apiService.getInstance().activiti.taskApi.listTasks(requestTasks);

==> "ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'basicAuth' of null
TypeError: Cannot read property 'basicAuth' of null
at eval (alfresco-js-api.js:646)
at Array.forEach (<anonymous>)"

This is how my app works step by step :

And this the login html :

<adf-login
  [backgroundImageUrl]="'./assets/images/loginbg.png'"
  [logoImageUrl]="'./assets/images/klinck.png'"
  providers="ECM"
  [showLoginActions]="false"
  [showRememberMe]="false"
  (success)="loadData($event)">
</adf-login>

Thank you for your help
