how to set a 'Select List' type custom field programably

[Deleted user]

I found solution here, it tells me use Option object instead of a string value. see https://answers.atlassian.com/questions/10431/how-do-i-update-the-value-of-a-selectcftype-field

But when I tried

Options options = this.getOptions(issueObject, cf);
Option newVal = null;
for(Object obj : options){
Option opt = (Option) obj;
if(opt.getValue().equals(strVal){
newVal = opt;
break;
}
}

issueObject.setCustomFieldValue(envrionmentType, newVal);

or

ModifiedValue modifiedValue = new ModifiedValue(issueObject.getCustomFieldValue(cf), newVal);

IssueChangeHolder changeHolder = new DefaultIssueChangeHolder();

cf.updateValue(null, issueObject, modifiedValue, changeHolder);

Neither of these two works.

Anybody can help me?

I got the answer from atlassian support.

thanks them and specially thanks for @Dieter' help on this.

I pasted the code below to save time for anyone encountering similar problem.

FieldConfig fieldConfig = timezoneCustomField.getRelevantConfig(issue);
final Options options = optionsManager.getOptions(fieldConfig);
            	
com.atlassian.jira.issue.customfields.option.Option tzOption = options.getOptionForValue(newTimezoneStr, null);
            	
if (tzOption == null) {
    log.error("Can't set custom field value to " + newTimezoneStr + " because it doesn't correspond to a valid custom field option.");
}
else {
    issue.setCustomFieldValue(timezoneCustomField, tzOption);
if(log.isDebugEnabled()){
    log.debug("Update TZ for issue '"+issue.getKey()+"' to '"+newTimezoneStr+"'");
}

What if you want to set a select field to null?

Thank you very much.

Thank You.

Before you call cf.updateValue you must set the change field in the issue as you already noticed:

issueObject.setCustomFieldValue(envrionmentType, newVal);

This must be done before cf.updateValue

Then i noticed you do not pass a fieldLayoutItem (1st argument) to cf.updateValue. I guess this doesn't work

The first argument can be retrieved from the following function

public static FieldLayoutItem getFieldLayoutItem(Issue issue, Field field) throws FieldLayoutStorageException {
        final FieldLayoutManager fieldLayoutManager = ComponentManager.getInstance().getFieldLayoutManager();

        FieldLayout layout = fieldLayoutManager.getFieldLayout(
                issue.getProjectObject().getGenericValue(),
                issue.getIssueTypeObject().getId()
        );

        if (layout.getId() == null) {
            layout = fieldLayoutManager.getEditableDefaultFieldLayout();
        }

        return layout.getFieldLayoutItem(field.getId());
    }

So to put it together

FieldLayoutItem flo = getFieldLayoutItem (issueObject, cf);
ModifiedValue modifiedValue = new ModifiedValue(issueObject.getCustomFieldValue(cf), newVal);
issueObject.setCustomFieldValue(cf, newVal);
IssueChangeHolder changeHolder = new DefaultIssueChangeHolder();
cf.updateValue(flo, issueObject, modifiedValue, changeHolder);

Hi Dieter,

Actually I have a null check before use the newVal in code, I did not paste here.

Is the way I use right?

Or can you help show how to use Option object solve this problem? thanks a lot!

Did you make sure newVal is not null? Are there any messages in atlassian-jira.log?
