How to create a Schedule in COD 7?

I've learned a lot about how COD 7 works in the last couple of weeks, still haven't quite figured out the view cod_session_schedule. (This is for the version cod-7.x-1.0-alpha4+1-dev)

The documentation has not quite kept up with the development of this great application, so the existing videos and docs don't help much. I can create all the components of a schedule -- time slots, rooms, sessions, speakers -- but how to get the preview to appear in cod_session_schedule is still an elusive mystery.

Any help, or even offer suggestions on how to troubleshoot this, would be quite appreciated. (My company wants to use COD for a big conference later this year, so I am highly motivated to get this working!)

thanks,
Rick
