Add user to list collector without removing the ones before

[F_bio Santos]

Hi everyone, I created a custom field on "task" table which will get the current assigned user everytime it changes without removing the one that is already there, I not sure on how to do this. Im thinking about trying a Business rule on "task" table with:

Before > Update

var assignedTO = current.getValue('assigned_to');
var listField = current.getValue('listColletorUsers');


listField  = current.listColletorUsers + current.assigned_to;

@F_bio Santos List collector is nothing but a comma separated string of sys_ids. Please check if the following script works.

var assignedTO = current.getValue('assigned_to');
var listField = current.getValue('listColletorUsers');
listField  =listField+',' + assignedTO;
current.setValue('listColletorUsers',listField);

Hope this helps.

Hi @Sandeep Rajput it worked, but for some reason it is getting the user 3 times. Could it be because I have:

before > update 

Assigned_to > changes

Update the script as follows.

var assignedTO = current.getValue('assigned_to');
var listField = current.getValue('listColletorUsers');
if(listField.indexOf(assignedTO)==-1){
listField  =listField+',' + assignedTO;
current.setValue('listColletorUsers',listField);
}

Hope this works for you.
