SPFieldUserValue User is null

Question

I have a list in which I can also view the version of each item. Suppose I have an item ItemX which has been modified by UserX, I then delete UserX and try to view the version item of ItemX which had been modified by UserX.

When I want to retrieve the information about ModifiedBy, the returned string value is null and I found it is because of this:

SPFieldUserValue userValue =
                        (SPFieldUserValue)userField.GetFieldValue(fieldValue.ToString());
SPUser user = userValue.User;//null

I thought of creating an SPUser, but found that there is no constructor available for that. Any ideas on how I can get around that problem? Thanks!

Answer 1

Try with EnsureUser method

SPUser user = web.EnsureUser(userValue.LoginName);
