AssigneeResolver

Determines the actual User the issue should be assigned to. This method is invoked when an issue is being created, edited, moved, etc.

This method is invoked to actually deterine the User the issue is assigned to. This method is invoked after validateDefaultAssignee(com.atlassian.jira.issue.Issue, java.util.Map).

Determines the default User the issue should be assigned to. This method is invoked when an issue is being created, edited, moved, etc.

When used in GUI operations, this method will be invoked after validateDefaultAssignee(com.atlassian.jira.issue.Issue, java.util.Map). However, it can also be called by itself (eg when creating an issue from an incoming email).

This method is called to validate input when a user selects 'Automatic' during an issue operation, e.g. creating, editing, moving an issue, etc.

This method allows the implementation of this interface to validate the input and report any errors back to the caller (most likely the user interface). Most often the errors reported are if the default assignee does not have the ASSIGNABLE_USER permission. This method is called before getDefaultAssignee(com.atlassian.jira.issue.Issue, java.util.Map).

The fieldValuesHolder holds values of issue fields that have been selected during the operation. For exmaple, if an issue is being transitioned through workflow and the Screen for the workflow transition shows 3 fields (e.g. description, fix versions, and assignee) the fieldValuesHolder will hold the values of these 3 issue fields. The keys of fieldValuesHolder are issue field ids that can be found in IssueFieldConstants.
