Steps to reproduce:
1. Go to Schedule Recordings
2. Select a workflow that does not have the hold for trimming option (for instance, ncast-mp4-distribution) and click on Schedule.
Nothing happens. In Firebug in Firefox (14.0.1), you can see the error "TypeError: this.fields.trimHold is undefined".
Workaround (if any):
Include a configuration_panel section with trimHold in that workflow.
