Michael,
Thanks, I think I remember this being a previous problem. So I just deleted
the entire ".cayenne" directory, and now it saves the datasource configuration
correctly (well at least for this one project). Thanks.
So, my next question is:
1. Until 3.1 re-design, what steps should I now take wrt the ".cayenne" dir to
ensure that my datasources are all available for all 3 of my projects?
a. do I need to re-create all of my datasources and then save
b. if I do step "a." then do I need to do anything else for the other
projects or is the "re-create" step sufficient.
Thanks,
Joe
PS I would have thought that you would have used the XML pattern as a solution
for the CM-level preferences as you did with the project files. (Your project
files are pretty much bullet-proof, and I can even make quick changes using
direct text-editing. IMHO this is an excellent design.)
