Empty customer fields (Assignee and Assagnee group) in escalation window shown in transition

[Matthew Van Kuyk]

Dears,

When having a transition for an escalation I get a screen for the escalation information. By default the Asignee and Assignee groups are set to the Assignee and Assignee goup of the issue. I want this custom fields to be blank as an escalation is typically done to another person or team.

I have tried to add a an condition on the transition, but this does not seem to work (Script runner)

import com.opensymphony.workflow.InvalidInputException;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.ModifiedValue;
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder;

try{
        
    def issueManager = ComponentAccessor.getIssueManager()
    def customFieldManager = ComponentAccessor.getCustomFieldManager()
    def cf = customFieldManager.getCustomFieldObjectByName("Assignee")
    def changeHolder = new DefaultIssueChangeHolder();
    cf.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(cf), ""),changeHolder);
    
    
   // log.error "Customer Request Type: " + cFieldValue;

    
}catch(Exception ex){
    
    log.error "REAL ERROR" + ex.getMessage()
  
}

Does someone know a solution for this?

Kind regards,

Matt
