Set issue summary to cascading select value on create

[Jennifer H.]

Hi all,

I'm using the below groovy script to set the issue summary of a sub-task to the value of "Product" (a cascading select field in the same sub-task) on create. (I took snippets from https://answers.atlassian.com/questions/197938/getting-first-value-from-cascading-select-custom-fieldbut it doesn't seem to be working).

Any suggestions are much appreciated!

import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.customfields.view.CustomFieldParams
import com.atlassian.jira.issue.customfields.option.Option

Issue issue = issue;

ComponentManager componentManager = ComponentManager.getInstance();

CustomFieldManager customFieldManager = componentManager.getCustomFieldManager();

CustomField customField = componentManager.getCustomFieldManager().getCustomFieldObjectByName("Product");

Object productValue  = issue.getCustomFieldValue(customField)?.getValue();

CustomFieldParams params = (CustomFieldParams) productValue;
if (params != null) {
Object parent = params.getFirstValueForNullKey();
Object child = params.getFirstValueForKey("1");
}

issue.summary = issue.summary + productValue;

I have used below code to get the value from single group picker field. This may give you some hint:

def cfg = customFieldManager.getCustomFieldObjects(issue).find {it.name == "Assignment Group"}

def cfgvalue =(List<Group>)issue.getCustomFieldValue(cfg)

String Agroup = ""

for(Group group:cfgvalue){

Agroup = group.getName()

}
