Scala support
Baldur Norddahl
"play new x -with scala" works. But changing "def index = render()" to
either "def index = <h1>test</h1>" or "def index = "hi"" fails with:
An unexpected error occured caused by exception VerifyError:
(class: controllers/Application$, method: index signature: ()Ljava/
lang/String;) Wrong return type in function
or
An unexpected error occured caused by exception VerifyError:
(class: controllers/Application$, method: index signature: ()Lscala/
xml/Elem;) Inconsistent stack height 1 != 0
I tried different versions of play and scala module but with no luck.
Am I doing something wrong here?

pull, you did 'cd framework' and 'ant' right? Also, once you do that
you will have to rebuild any non-core modules that aren't binary
compatible (probably all of them) by changing to each module's
directory and running 'play build-module'.
Thanks, Chris

I will look into it.

However, "bzr pull" from r820 to r825 takes over a minute! When will
Play officially move to GitHub?

Mine is 2.0.1, from MacPorts.
I have not been able to follow the example from:
http://www.playframework.org/documentation/1.1-trunk/scguide1
Error:
value QueryFunctions is not a member of package play.db.jpa
import play.db.jpa.QueryFunctions._
I think it should be:
import play.db.jpa.QueryOn._
but don't know how to proceed because I'm new to Scala.
Another typo at scguide3: Bootstrap.java should be Bootstrap.scala?
peter hausel
the scala module now lives here:
http://www.playframework.org/modules/scala
ngocdaothanh
Wrong:
import play.db.jpa.QueryFunctions._
find[Post]("order by postedAt desc").first
Right:
import play.db.jpa._
QueryOn[Post].find("order by postedAt desc").first

separate scala module (plus the new doc) now lives here:

The file scguide2 in the latest source code still has this line:
import play.db.jpa.QueryFunctions._
Maybe the doc should be fixed?
peter hausel
right now. The guide will be rewritten for the new standalone module
once the API is finalized (we are close now). For the up-to-date
documentation, please see http://www.playframework.org/modules/scala
. thanks peter

I use the latest trunk versions of Play and the Scala plugin. The
first request to "yabe-with-scala" sample gives:
RuntimeException occured : Cannot load fixture initial-data.yml: null
Fixtures load "initial-data.yml"
2.
I'm new to Scala. Looking at the source of the Scala plugin, I see
that 4 spaces are used to indent at many files. Shouldn't Scala source
code be indented by 2 spaces?
peter hausel
that gets merged, the error will go away. I will keep you posted.
