How to query a Group picker customfield ?

[passive 49]

hi guru,

Need help urgently on trying to query a GroupPicker customfield. I wrote the following code in the script console using the scriptrunner groovy script for the query but instead of returning the group_name, it is returning a class like object  "com.atlassian.crowd.embedded.impl.ImmutableGroup@c53".

Any ideas what is wrong with my code ? Thanks in advance.

// issue key : "RMD-2"

// group picker customfield : "customfield_10204"

//###########################################

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.security.groups.GroupManager
import com.atlassian.jira.user.ApplicationUser

def issue = ComponentAccessor.getIssueManager().getIssueByCurrentKey("RMD-2")
def customField = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("customfield_10204")
def abc= issue.getCustomFieldValue(customField).toString()

if (abc==null) {return "fish !"} else {return "1. => "+abc + "    from => "+customField.toString()}

//
// returns: 1. => [com.atlassian.crowd.embedded.impl.ImmutableGroup@c53] from => amt_to_WIP
//

Thanks to guru Ari Hermawan who helped me to fixed the code with the following additional lines.

if ((issue) && (customField)) { // check both Issue and Field exist
def customFieldVal = issue.getCustomFieldValue(customField)

if (customFieldVal) { // if object exists
if (customFieldVal instanceof java.util.Collection) { // if it's a Collection
abc=customFieldVal.getAt(0).getName() // get the first element's Name
}
else abc=customFieldVal.toString() // else it's a string
}
else return "NOT_FOUND"
}

return abc
