Assign Task to Group and send E-Mail

Hi all,

I'm stuck in my project and hope you can help me.

In the first Task of the project I select a Group and get the GroupId as String back.
I need to assign the second Task to members of this Group, I think via Actor-Filter.
I have tried this:
List users = apiAccessor.getIdentityAPI().getUsersInGroup(accessAuthorizationInput.groupId.toLong(), 0, 100, UserCriterion.FIRST_NAME_ASC);
for (User user : users) {
def departement = new DepManager();
departement.firstname = user.firstName;
departement.lastname = user.lastName;
departement.title = user.title;
accessAuthorizationVar.addToDepartement(departement);
}
but it doesn't work.

The next thing where I'm stuck is sending an Email to this Users in the Task.
I have tried this toScript with the Email-Connector:
import org.bonitasoft.engine.identity.ContactData;
import org.bonitasoft.engine.identity.Group;
import org.bonitasoft.engine.identity.User;
import org.bonitasoft.engine.identity.UserCriterion;

Group groupSelected=authorization.getGroupId();
List usersInGroup=apiAccessor.getIdentityAPI().getUsersInGroup(groupSelected.getId(), 0, 100, UserCriterion.FIRST_NAME_ASC);
StringBuilder sb=new StringBuilder();
for (User user:usersInGroup){
//get professional contact data
ContactData contactData = apiAccessor.getIdentityAPI().getUserContactData(user.getId(), false);
if (contactData!=null && contactData.getEmail()!=null && !contactData.getEmail().isEmpty()){
sb.append(contactData.getEmail()).append(",");
}
}
return sb;
but also get errors.

Thanks for your time.

OK - so what are the errors? We are not mind readers...

Hi, sry of course.
But I also see this is what I use for Actor:
import org.bonitasoft.engine.identity.User;
import org.bonitasoft.engine.identity.UserCriterion;

List result = new ArrayList();
List users = apiAccessor.getIdentityAPI().getUsersInGroup(authorization.placeholder.toLong(), 0, 100, UserCriterion.FIRST_NAME_ASC);
for (User user : users) {
result.add(user.id)
}
return result

placeholder is the String with the GroupId

This is the Error:

A Tip on displaying CODE/LOGS correctly in Posts:

Do not use the Supplied Buttons above, for some reason they refuse to work correctly, and despite bringing it to Bonitasofts attention, it's low priority.

To Show Code/Logs correctly use

< code >
your code/log
< /code >

removing the spaces to allow the showing of code/logs correctly as here:

  1. your code/log

Thanks and regards

You say I need to assign the second Task to members of this Group, I think via Actor-Filter.

It's not clear - do you want to assign the second task to the group so only ONE user does it, or do you want to assign the second task to ALL members of the group so that each does it?

If the former just assign to the group, if the latter then you cannot do this via Actor-Filter, you will need to create X task and assign them individually.

Regarding the Actor errors:

  1. org.bonitasoft.engine.expression.exception.SExpressionEvaluationException: FLOW_NODE_INSTANCE_ID=200010 | Declared return type class java.lang.Long is not compatible with evaluated type class java.util.ArrayList for expression userId()"

you are trying to return ArrayList when you should be returning Long...you have to return the right type.

and for the email error it is a similar issue:

  1. Groovy script throws an exception of type class org.codehaus.groovy.runtime.typehandling.GroovyCastException with message = Cannot cast object '141' with class 'java.lang.Long' to class 'java.util.List'

You cannot cast Long to List

Hi again,
I need to assign the task to a group, so that on Member of this Group can take it and do it.
The Group is like I said, selected in the Form, but I do not get how it can be assigned to it. So I tried to get the GroupId back and make an Actor-Filter.
Is there a better way?
I posted my script in the beginning, can you tell me what needs to be changed to get it working?
Thanks and regards

There's near no need for any code for this one, here is what I would do:

You already have the groupid (as a string) that's JSON for you...
In your output operation/task change this to an int using

  1. int result = Integer.parseInt(groupid);

then

Ignore everything I've just said :) ... took me a while but here is the correct way to do it...I think ;)

Define an Empty Group in the Organization (dynamicGroup)
Define a new Actor (dynamicActor) and assign the Empty Group (dynamicGroup)
//* the above makes sure the process has a defined Actor/member pairing for deployment

Define your process and make sure the Pool and Every human task have the appropriate Actor defined. For the task(s) you want to be assigned based on Selection assign the new Actor (dynamicActor)

In your code for assigning the process to the group

Get the groupId

then use one of the following to add the group to the new Actor (dynamicActor)

  1. addGroupToActor(long, long) - Method in interface org.bonitasoft.engine.api.ProcessManagementAPI
  2. Maps the group to the actor.
  3. addGroupToActor(String, long, ProcessDefinition) - Method in interface org.bonitasoft.engine.api.ProcessManagementAPI
  4. Maps the group to the actor of the process definition.

See: http://documentation.bonitasoft.com/javadoc/api/7.4/index.html (find addGroupToActor)

You will have to see exactly how it works, but I think you will have to add the group to the Actor before starting the process...

The process then should be visible to all actors of the selected group.

I can see one possible issue and that is starting multiple versions of the process and changing the involved groups on the actor while other processes are executing, it may cause some hick ups...as I say You will have to see exactly how it works.

Otherwise I would fix the issue of having to select a group to execute, why would you want to do this?

Sorry but not tried it...

Hi,
ok i have tried to use addGroupToActor(long,long) by using addGroupToActor("201".toLong(), authorization.placeholder.toLong()).
201 is the ID of swapGroup, the actor of the task.
But I get

I dont know, if it is right.
I just made a new Bussinesobject, test1.
so I just mad an operation of a Java-Method setTest1 then a script addGroupToActor("201".toLong(), authorization.placeholder.toLong())

Submitted by Sean McP on Mon, 05/15/2017 - 12:07

http://documentation.bonitasoft.com/javadoc/api/7.4/org/bonitasoft/engin...

But shouldn't you actually use the full method of the API

processAPI.addGroupToActor("201".toLong(), authorization.placeholder.toLong())

I also tried to understand what is done here: link

But I just cannot understand how he does it.
