Hi,
We are using jira6.1.7 and jira agile6.3.3. when trying to create the sub task in jira agile we are getting "Multiple Assignees: Failed to set field" after choosing the multiple user once i click on create i am getting the error. But at the same time when we try to create the subtask in jira using Multiple user picker we are not getting any error.

Can anyone suggest me how to resolve this error.
Thanks,
Jayasingh
