Our teams would like to have the fixVersion and other fields cleared whenever an issue is cloned. Our solution is to use the "clear field value" function provided by the jira suite utilties. This is used as a post-function on the create step. Our users have accepted the fact that the fields would be cleared for newly created issues as well as cloned issues.
This method seems to work fine for custom fields, but is not working for the FixVersion field. Is this a known limitation of the jira suite utilities function? I don't see anything in the documentation that indicates system fields are any different than custom fields when using this particular function.
