Jira User Object Types In Scripts Explanation

Stefan Johansso3

I have when writing scripts come across several ocations when i get errors such as "this user type cant be cast to that user type". And when i access the issue.assignee/assigneeId/assigneeUser - whats the difference? And what kind of user does e.g. a User Single Select want?

Is there somewhere I can read about all this?

It's confusing. This is the best explanation of the different types of users and why they exist: https://developer.atlassian.com/display/JIRADEV/Renamable+Users+in+JIRA+6.0

issue.assignee and assigneeUser are synonyms and return a com.atlassian.crowd.embedded.api.User. I don't know why two methods are required.

assigneeId just returns the username. Or could it be the user key? I don't even know.
