I think that I’ve found the problem that causes the last test in
model_and_lib_test.rb to fail.
The problem is: with two models Something present in two plugins
plugin_a and plugin_b the one in the latter plugin one should, but the
former one actually is loaded.
This only happens when one uses Dependency constant autoloading for
loading the class (as I did in the test). It doesn’t happen when one
explicitely requires the file. This is because the plugin paths are
inserted into $LOAD_PATHS in reverse alphabetical order but appended
to Dependencies.load_paths in alphabetical order.
This behaviour seems to have around since at least Rails 1.2.x
I’ve also posted to the rails-core list:
