It looks like you probably have some other dependencies somewhere or
old jars pointing to the old lift version.
Please first try mvn clean jetty:run, and if that doesn't work, run
mvn dependency:tree to try and find where the other version of lift-
webkit is coming from. If you're still stuck, paste the output of
dependency:tree please!

Ah hah!
I'd strongly recommend you upgrade to Lift 1.1-M8. It's faster,
more stable
and better supported than 1.0.

Sure thing, it's quite long though :)
Just one thing, i added the following for it to compile (I want to
return List[User] not List[TagUser] : .map(_.user.obj.open_!)
So in all it looks like this
def getTopUsers(in: Int) :List[User] = {
TagUser.findAll(By(TagUser.tag, this.id), In(TagUser.user,
User.id,
OrderBy(User.followers_count, Descending), MaxRows[User](in)))
.map(_.user.obj.open_!)
}
What version of Lift?
