I am facing weird issue with Set Item Permissions. I created Site Column (Requestor - People picker) which accepts only People (no people and group) and added Requestor column in Workflow. However, when I tried giving Full Permission to Requestor, it shows as "AssociationColumn:null". Anybody can suggest as what am i doing wrong?

can you try using a column created at list level (not site column) and see if you get the same behaviour?
