how to set 'Request Participants' using behaviours(script runner)?

[Bartek Zukowski]

I want to create a behaviour to set 'Request Participants' based on a selected value in some single select list but I don't know what values does this request-participants-field accept.

I tried something like this:

def market = getFieldById(getFieldChanged()) //behaviour is used when changing this field
def reqParticipants = getFieldById("customfield_12211") //this is 'Request participants' field
def selectedOption = market.getValue() as String
if (selectedOption == "something1")
 {
    reqParticipants.setFormValue("user1")
 }

But it doesn't do anything with user names (users that actually exist in my Jira).

I tried using e-mail addresses instead of user names but with no positive effect as well.

I do tried to use a post function to copy field value from 'watcher field' (that can be populated by this behaviour) to 'request participants' and that worked. But that is only a post function and behaviours seem to be more elegant and universal solution.

If some post function is able to insert a proper value to 'request participants' field then I think that it should be also possible to use behaviours but I don't know what is the proper way to do this.

Any ideas what am I doing wrong?

An easy way to do this is using the Collective Issue View for Service Desk Plugin. 
This plugin adds automatically groups of users as Participants.

Thanks a lot, Kristian! That looks exactly like what I was looking for.

You may also find the article at https://confluence.atlassian.com/jirakb/how-to-automatically-add-request-participants-when-creating-an-issue-777026955.html here which shows how you can set users in the request participants field using a Post function which you may be able to convert into a behaviour.

Thanks

Hi Bartek,

Service desk uses system fields which cannot be set by the normal JIRA API.

However the latest versions of JIRA Service Desk contain a rest API which will allow you to use a Post Request to set Request participants. 

An example of the Add Participants method in the API can be viewed here.

I hope this helps

'Request participants' is of type 'Request participants'  - it is a locked system custom field that is added by JIRA Service Desk. It works somewhat like multi user picker but not exactly, because you can add also an e-mail address there if a user doesn't have a JIRA account.

It stores people involved in an issue - so it's like a field to store watchers but in a different way. Our 'watcher field' (that is added by installing Watcher Custom Field for JIRA add-on) is easily populated by placing user names like:

watcherField.setFormValue("user1,user2,user3")

What type of field is Request Participants? You can see that in Admin -> Custom Fields. May be a multi user picker?
