Calling getUserByID() works in global scope but not in application scope

[pathat]

Hello.

I have a business rule (BR) which has a custom script which gets information about a user other than the user I am currently logged in as, just like the following:

var ourUser = gs.getUser();

gs.print(ourUser.getFirstName()); //should print out the first name of the user you are currently logged in as

ourUser = ourUser.getUserByID('abel.tuter'); //fetched a different user   --> Exception thrown here when in APPLICATION scope

gs. ­print(ourUser. ­getFirstName()); //this should be the first name of the user you fetched above

This script was working fine when the BR has a GLOBAL scope. But the same script fails when it calls ourUser.getUserByID() in another BR which has an APPLICATION scope. The error is: TypeError: undefined is not a function

Thoughts anybody?
