The EML 2 Dataset actor parameters EML File and Data File look for file paths. 
If I open a new workflow, add the EML 2 Dataset actor, and browser to two
files, their full paths are recorded in the actor.  I can save this workflow
and open it with no problems.

If I place the saved workflow in the same folder as the EML and data files,
open the saved workflow, edit the EML 2 Dataset actor, and browse to the same
two files, then the full paths are replaced with local paths relative to the
workflow's xml file (i.e., just the filename).  If I save this modified
workflow and try to reopen it, I get an error: 

Data entity : Dailyrain1992.txt,  failed to be downloaded and please check the
data link in metadata

The URL is a zip of four files: 
EML file: judithk.609.21.xml
Data file: judithk.657.1-Dailyrain1980.txt
first workflow (no error on load): full path.xml
second workflow (error on load): filename only.xml
