Hey,
I try to cover assign issue to the last workflow executor, I mean for example if person X assign issue to "for more info" and that issue will be already assign Y script should assign issue to X person 

Thanks in advice for all hint how to do it

The solution would involve:

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()
        def changeHistories = changeHistoryManager.getChangeHistories(issue)

        def previousAssignees = changeHistories.collect {history ->
            history.getChangeItemBeans().findResults {ChangeItemBean change ->
                if (change.getField() == "assignee") {
                    return change.getFrom()
                }
            }
        }.flatten()

Should give you a list of all previous assignees, so you can take the last one or whatever you need.
