Turns out my BasicTest was an object, not a class, and the '$' in the classname was confusing the regex on Router:331.  Changing it to a class has gotten me past this error. 

Just need to sprinkle a little java.util.regex.Pattern#quote to taste... :)

Hey folks,

So far I'm pretty impressed with the conciseness and apparent simplicity of Play, and really happy that Scala support is available!

Now, I'm trying to follow along the tutorial with a recent nightly (1.1 unstable, r715) and running into a few problems.


First, in BasicTest, this line:

import play.db.jpa.QueryFunctions._

...should probably be QueryRunner, right?

And, when I try to open /@tests, I get this:

Oops: IllegalArgumentException
An unexpected error occured caused by exception IllegalArgumentException: Illegal group reference

play.exceptions.UnexpectedException: Unexpected Error

Any hints?

Thanks!

Ok thank you.

The tutorial is effectively out of date, but API are not yet stable.
