[Jessy Li]

Hello, I have a field called Bug Examiner. Can I do post action in transition that 1.check if the bug examiner is not empty, then update assignee?

Here it is:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.fields.CustomField

if(ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Bug Examiner").getValue(issue) == null){
    //Set new asignee
    issue.setAssignee(ComponentAccessor.getJiraAuthenticationContext().getUser().getDirectoryUser());

    //store changes to database
    ComponentAccessor.getIssueManager().updateIssue(ComponentAccessor.getJiraAuthenticationContext().getUser().getDirectoryUser(), issue, EventDispatchOption.ISSUE_UPDATED, false)
}
