[IDV #VFL-607764]: Problem getting time dimension specified for loading data using 'Directory' option and looping over time

Hi Dave,

There should't be anything else if all of the files live in the top level
of the directory identified in the scan tag. How is your directory structure
laid out?

Also, when you load the ncml file, what Data Source Type are you using
(the drop-down box on the Data Choosers Tab)?
