There are a number of ways to get issues from IswIssueObjRefs. This article describes the simplest way to get all issues with a reference to an item, and get an attribute of an issue using the SystemWeaver API.
Example
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[0].Issue; //Getting the attribute with SID = "AT_SID" IswAttribute attribute = issue.Attribute("AT_SID"); }
