Also, the page doesn't time out, it just attempts to load without end. I have been unable to determine how to definitely reproduce this problem and that's why I say it appears to be ra...

Coming from a J2EE dev background, I love the idea of Grails....all the benefits of using enterprise Java (Spring, Hibernate, etc. ), but with the simplicity of Rails (scaffolding, convention over configuration, Groovy scripting, etc.).

I've used a test file of my own (hard-coding which fields mean what) and it works great. But of course I can't leave the field references hard-coded like that, so my next ste...
