I tried a quick test with a selectManyListbox and get the same error. Regarding setting a breakpoint, I'm having trouble getting my debugger (I'm using NetBeans 5.5.1) to attach, so I that may be yet another problem to resolve. Thanks for your help...I'll post back if I come up with something useful.

I don't think your situation is related to Users.equals() in this case, but maybe I missed something. I hadn't read the article until now, but it's just saying (like I did) that having an equals() method using == is the general reason for this error [Object's equals() doesn't account for the fact that the original object and the restored serialized object are not the same object]. At this point, I guess you need to set a breakpoint at the code generating the error, and examine the state of your variables to see why you got there. Maybe there's a bug in SelectManyPickList. Can you try testing it with a SelectManyMenu/SelectManyListBox (or whatever else is there by default) and see if it generates errors? I tried using SelectManyPickList a couple weeks ago, but it was too primitive to do what I wanted -- I ended up using two t:dataTables with server-side-processing buttons to move selected items between the lists.
