There are a number of ways to get issues from IswIssueObjRefs.

to an item, and get an attribute of an issue
using the SystemWeaver API.
private static void GetIssueFromIssueReference(IswItem item)
//Get all issues that has a reference to the item
IswIssueObjRefs issueObjRefs = item.GetAllIssueRefs();
//Getting the first issue in the list
IswIssue issue = issueObjRefs.Issue;
//Getting the attribute with SID = "AT_SID"
IswAttribute attribute = issue.Attribute("AT_SID");
