I am running into a ghost of a problem. It happens sporadically. It has to do with controllers reloading after changes. Most times I am able to work around by reverting changes and starting fresh, however I am currently stuck. Below is the stacktrace.
File /Users/mcroteau/Development/projects/greenfield/grails-app/controllers/greenfield/DataController.groovy changed, recompiling...

Here is one project it is currently happening in: https://github.com/opengreenfield/greenfield - branch internationalization, DataController. Im ok with deleting things.
Thank you in advance for your help!
I see that your package definition and folder structure do not match. I am guessing grails gets confused by this. Try lining them up.
