Hi again,
Doing a little more debugging, I added the following in subprocess.rb in
self.lookup_subprocess:
# maybe subprocess :ref => 'uri'
subtree = fexp.context.reader.read(ref) rescue nil
require 'pp'
pp subtree
pp subtree.class
I get the following:
"/home/devel/Workflow/pdefs/XX-initialize-station.rb"
String
20110317-bebinibiba RuntimeError
20110317-bebinibiba no subprocess named

So for some reason, as I said, Reader#read is returning the same String
passed in instead of actually reading the file and returning the tree. I've
tried prepending 'file:' and 'file://' to the absolute pathname to no avail.
I've also tried using relative paths (because of our project setup, the
pdefs directory is 2 levels above ruote-kit, so the path is
"../../pdefs/initialize-station.rb")
And yes, the file does exist :)
This is driving me crazy!
