Thanks for your help.  I finally figured out the problem: I needed to 
name my class ux_tx_cal_controller instead of ux_cal_controller.  This 
is obvious to me now, but it wasn't clear yesterday since the Core API 
docs always refer to system classes (e.g. tslib_content) that have no 
tx_ in front.  Oh well!

Cheers,
