ensime on mac almost working, syntax checking after save stop working

Question

Just getting started in Scala programming. I got an environment set up using emacs, sbt, ensime according to the instructions here. (http://jawher.net/2011/01/17/scala-development-environment-emacs-sbt-ensime/)

It worked great for a couple of days, but then when I exited emacs and restarted I couldn't get the syntax check working (the check that happens after saving a buffer).

I start ensime after openning the file, and I see on the mode line that it says that ENSIME: Connected. But for some reason, I stopped getting the highlights for errors in the file.

Any help? It's driving me nuts.

Note: I can do other things with ensime, like starting a sbt subprocess.

thanks wing

Got some more info... I noticed that when it doesn't work, the *inferior-ensime-server* hangs on the scala> REPL

When it does work, it goes past the scala> prompt and enters swank (this works on my linux machine)

It almost seems like the ensime emacs scripts are failing to find something in the scala stream.

You can check ensime's emacs buffer for errors and publish them here.
