Assign task in k2 studio workflow to users retrieved from SharePoint people picker field

Thank you DavidAerne for your reply,

I am new in K2, i tried to add one user only first of all for testing purpose.

but i am getting an error : 28083 ServerEvent : The email address : k2:domainusername , is invalid.

knowing that the user has a valid email , please let me know if i missed up some configuration or anything else.

Regards.

Here is how I successfully did it.

1. I first add the "Get Reference User" event and dropped the item reference field onto the User ID field of the event.
2. Gave the Reference a good name and hit finish, e,g, ResponsiblePerson
3. Then I created 2 data fields, one to store the Claims-formatted-login-name, and the other store the cleaned-up-login-name.
4. Then I added the Data Event for assigning the Claims-formatted-login-name data field
5. In the source field, I added the ResponsiblePerson.User. LoginName reference
6. In the destination field, I added the Claims-formatted-login-name data field
7. Then I added another Data Event for assigning the Cleaned-up-login-name data field
8. In the source field of the data event, I added the Mid(Text, Start)(String) Text Expression
9. In the Mid(Text, Start)(String) expression, I added 8 as the start integer, and added Claims-formatted-login-name data field in the Text string.
10. In the destination field, I added the Cleaned-up-login-name data field
11. I then added a new default client event
12. On the client event's destination user, I added the Cleaned-up-login-name data field
13. That was pretty much it, the task was now able to be assigned to the correct destination user from the people picker.
