Issue with Javascript include in Rails app

I'm using Rails 3.2.8. When the app is deployed access the view that is including a javascript:

<%= javascript_include_tag "epiceditor" %>

Heroku fails with this log:

ActionView::Template::Error (/app/app/assets/javascripts/epiceditor.js.erb has already been required

I've checked some possible solutions, like checking for any reference that may trigger a circular dependency, or simply removing it in case it is being included somewhere else, which isn't. So, if I include it, I get this "has already been included error", if I don't , then the file isn't included at all.

My config/application.rg has this

    config.assets.initialize_on_precompile = false

And applications.js has this:

//= require jquery
//= require jquery_ujs
//= require tabs

It might be important to note that the file the tag is referencing is "epiceditor.js.erb", since it has some embedded Rails code that I needed.

Thanks for your help

EDIT:

I believe this is a bug in Sprockets. If I update Rails to 3.2.9rc2, the error is now this: ActionView::Template::Error (Asset logical path has no extension: epiceditor/.js

but of course the extension in epiceditor is epiceditor.js.erb, and I've tried being explicit about it in the javascript_include_tag as well.

I found the bug. It turns out that inside the .js.erb file I'm calling

<% asset_path 'epiceditor/' %>

which should expand to the path where all the epiceditor file are placed, but instead is actually loading the file itself in recursive manner. This is expanding properly in the development environment but not in the production environment. Funny, right? The reason for this is that is adding a digest. So I fixed the whole issue with this:

<%= asset_path 'epiceditor/', :digest => false %>

and now it does expand to the directory, and doesn't fall into the recursion trap.

Hope this saves some time for someone!
