I've been seeing the same problem when trying to upgrade an application from Rails 2.1.2 to 2.2.2. I had set up a controller to serve static content wrapped in the site's template. One of the users dropped some JPEG files into the /app/views/static directory, and that seems to be jamming up the works with 2.2.2.

Now I know how to solve the problem (by removing the the non-.html.erb files), but I'm wondering why there is a difference between 2.1.2 and 2.2.2.

Theoretically it was to allow for all the erb templates to be loaded up once at load time [it just happens to attempt this weirdness with non erb files, too...I'm not sure if it's a bug or not...I believe I filed a report of it on lighthouse]. Cheers! -=R

Is there any way to exclude certain template file types (or non- template files) from being preloaded, say by their file type? Specifically, I was thinking of jpeg, swf files, etc. which we do not (!) wish to be loaded/parsed at startup time. Could there be a configuration option which handles this?

I think that trunk was updated recently to handle them better [i.e. only .rhtml -> compile].
