Ah, wait - I see what's going on. It's not that it's not tracing the user2 variable properly, it's that I'm creating the representation before I've assigned any values to user2 - so it's got nothing to define the color range from. That only gets changed when I reset the representation after updating user2.

Subject: Tracing on color by properties
If I set up a selection that's colored by, say, user2 and then change the values in user2 without changing frame, nothing happens to the displayed color. To get it to change, I have to change the representation to color by something else, and then back to user2. Interestingly, from that point on the displayed color immediately reflects any changes made to user2 - which is exactly what I want (I want to update representation colors on the fly in an IMD session according to calculated values). Is it possible to get that trace turned on from the moment the representation is created, or turn it on with a tcl command?
