Exception when trying to create a new issue

Since the upgrade to JIRA 7 when trying to create a new issue this exception is displayed:


Exception occurred: java.lang.IllegalArgumentException: Multiple entries with same key: customfield_10402=com.atlassian.jira.rest.v2.issue.IssueBeanBuilder2$FieldData@3b7ab06a and customfield_10402=com.atlassian.jira.rest.v2.issue.IssueBeanBuilder2$FieldData@56583aab


  1. the issue is created although the message is shown (but the dialog is still open, displaying the error message)
  2. the customfield is neither necessary nor displayed in any screen related to this issuetype or project
  3. the customfield exists only once in the database and its context is highly restricted to another project

Any ideas on this?

It means that two values for customfield with id 10402 have the same id. 

If you use server version you can try to get doubled customfield values with this SQL:

	, customfieldvalue.CUSTOMFIELD
group by
	, customfieldvalue.CUSTOMFIELD
	COUNT(customfieldvalue.ID) > 1

I got similar troubles when inserted values into custom field via SQL.

Exactly. Never change a JIRA database with SQL (unless you *fully* understand what you're doing. Which most people don't)

This query returns no results.

Is that field a ranking type field?

No, its a rarely used customfield restricted to one project.

Ok, what type of field is it? This error looks like you've got more than one value for a single-select field. You might have to delete one.

you're right, it's a single-select field. I'll have a look into this.
