I'm doing Scala web development using the Play framework's scala module, and using Emacs+Ensime to edit the code. Sometimes even when Ensime shows no errors, Play will still show a compilation error for a .scala file (like a type parameter mistake, or even a typo'd override, which is such a basic error).
How can I make ensime show all compilation errors that Play would show?
I'm using Scala 2.8.1, with ensime_2.8.2-SNAPSHOT-0.5.1 (which seemed like the best of the available options when I downloaded it).
