0) Under Windows XP, on Desktop create directories: 
test/data
test/workflow

1) Save attached dataFile.txt into test/data/

2) Save attached workflow.xml in test/workflow/

3) Launch kepler-devel. Open workflow.xml. Double-click FileParameter, Browse
to test/data/dataFile.txt

Note on XP the path created in FileParameter is:
file:/C:/Documents%20and%20Settings/visitor/Desktop/test/data/dataFile.txt

The FileReader actor can use such a path, but Rexpression will have trouble
with it.

4) Execute workflow

You'll see an error in the Display:
  cannot open file
'file:/C:/Documents%20and%20Settings/visitor/Desktop/test/data/dataFile.txt',
reason 'Invalid argument'

5) If you change FileParameter by hand (remove file:/ and replace %20's with
spaces) to:
C:/Documents and Settings/visitor/Desktop/test/data/dataFile.txt
and execute the workflow, it will work (you'll just get a warning from
Rexpression).

6) If you move dataFile.txt to test/workflow/, and then configure FileParameter
and Browse to test/workflow/dataFile.txt, the path you get is dataFile.txt.
It's not an absolute path which is what Rexpression wants. Rexpression will
give an error if you try to execute.
