Using Bonita 6.2.2

I have look all over the forum and have found various answers but none of them work. Possible they are all for version 5.x?

I did fond[this post](http://community.ofelia.com/answers/how-can-i-get-full-user-list-actor-groovy-script) that got closer. It ends up getting a list of users in the form of ActorMember. What I need to their email addresses. I cannot figure out how&nbsp;to get email addresses because of my poor Groovy skill. I see [in the API documentation here](http://documentation.bonitasoft.com/javadoc/api/6.2/index.html?org/bonitasoft/engine/api/TenantAPIAccessor.html) that ActorMember has four methods. I can get the member ID but I don't know what to do with it.

I also found an old extension that is a jar but I am not sure how to use it.

I also found an old 5.x example process with this script:

import org.ow2.bonita.util.AccessorUtil

def candidates = AccessorUtil.getQueryRuntimeAPI().getTaskCandidates(activityInstance.getUUID())  
 def to=""  
 for(user in candidates){  
 &nbsp;&nbsp; &nbsp;if(to!="") to+=","&nbsp;&nbsp; &nbsp;  
 &nbsp;&nbsp; &nbsp;to+=AccessorUtil.getIdentityAPI().getUser(user).getEmail()&nbsp;  
 }  
 return to

The issue with this one is that line:

> import org.ow2.bonita.util.AccessorUtil

Seems like there are a lot of people in the forums that are looking for the same answer.

Is there someone that can help me get one of these running in 6.2.2?

Hi Eric,&nbsp;  
 The Bonita API has changed in version 6.&nbsp;  
 Objects used in V5 are not the same that are used in the V6.&nbsp;  
 For example: The class "AccessorUtil" in the V5 has been replaced by the class "TenantAPIAccessor" in V6.&nbsp;

If you use the groovy script editor embedded in the Bonita Studio, you can use the variable "apiAccessor" provided in the list.&nbsp;

To retrieve the list of candidates to a user task you can use something like this:&nbsp;  
 ProcessAPI processAPI apiAccessor.getProcessAPI = ();&nbsp;  
 List \<User\> listUsers = processAPI.getPossibleUsersOfPendingHumanTask (ActivityInstanceId, 0, Integer.MAX\_VALUE);&nbsp;

To retrieve the user's professional email you can use something like this:&nbsp;  
 ContactData ContactData = identityAPI.getUserContactData (user.getId (), false);&nbsp;

Hope it can help you  
 Karim

Hi,

If you want just the professional email of the user assigned to the task, on your task, you need to add a Groovy connector on Finish, and add the following code :

> import org.bonitasoft.engine.identity.ContactData;
> 
> ```
> <p>
> <br />
> ContactData contactData = BonitaUsers.getUserProfessionalContactInfo(apiAccessor,taskAssigneeId);<br />
> return contactData.email;</p>
> 
> ```

&nbsp;

If you want to retieve just the candidates to a user task, you need to add a Groovy connector on Enter, and add the following code :

> import org.bonitasoft.engine.identity.User;  
> import org.bonitasoft.engine.identity.ContactData;
> 
> &nbsp;
> 
> ```
> <p>
> // Get the users attached to the actor member of the human task<br />
> final List &lt;User&gt; users = apiAccessor.processAPI.getPossibleUsersOfPendingHumanTask(activityInstanceId, 0, Integer.MAX_VALUE);</p>
> &nbsp; // Get the professional email of the users<br />
> final List&lt;String&gt; professionalEmails = new ArrayList&lt;String&gt;(users.size());<br />
> for(final User user : users){
> <p class="rteindent1">
> &nbsp;&nbsp; &nbsp;ContactData contactData = BonitaUsers.getUserProfessionalContactInfo(apiAccessor,user.id);<br />
> &nbsp;&nbsp; &nbsp;professionalEmails.add(contactData.email);</p>
> }
> 
> <p>
> return professionalEmails;</p>
> 
> ```

Best regards,

```
<p>

Source for learning API =\> what i usually do is look at the source code of Bonita. That’s what I did to be able to write a userFilter for multiple user from variable…

Bonita 6.5, I’m using an e-mail connector that gets its e-mail addresses for all possible candidates (not sure the function getPossibleUsersOfPendingHumanTask exists in 6.2)

def emails = []; def users;

def process\_api = apiAccessor.getProcessAPI();  
def identity\_api = apiAccessor.getIdentityAPI();

def human\_task\_instance = process\_api.getHumanTaskInstance(activityInstanceId);

def start\_index = 0;  
def max\_results = 100;

while( users = process\_api.getPossibleUsersOfPendingHumanTask(human\_task\_instance.getId(), start\_index, max\_results )) {  
for( user in users ) {  
try {  
def pro\_user = identity\_api.getUserWithProfessionalDetails(user.getId());  
def email = pro\_user.getContactData().getEmail();  
if( email != null ) {  
emails.add( email );  
}  
}  
catch( Exception e ) {  
}  
}  
start\_index += max\_results;  
}

emails.unique();  
return emails.join( ‘,’ );

Do you want the email of the user assigned to the task, or all users of the actor of the task ?

And, do you want the professional or the personal email ?

Thank you for the reply. I was out yesterday so this is the first I have been able to look at this. When I use the code above I am getting errors. When I isolate the code to just:

> ProcessAPI processAPI apiAccessor.getProcessAPI();  
> return "Hello";

I get:&nbsp;

> ProcessAPI cannot be resolved. It may lead to runtime errors.
> 
> ```
> <p>
> processAPI cannot be resolved. It may lead to runtime errors.</p>
> 
> ```

What may be wrong?

Also, is there a good source for learning how to use 6.6 API?

Hmmm... I am having an issue. When I tested the script on one task it wen well. Now I have copied the email connector to other tasks. Now I get errors:

this worked for me thanks
