While looping through my sharepoint's list fields, I found that there are some "in-built" Sharepoint fields (for example, Check In Comment) that are lookup fields. However, when I try to use
lookupField.LookupList
to find which list they are pointing at, I get an error that lookup list does not exist. Can someone tell me why this is so? If it's a lookup field, it surely MUST have a lookup list right?
