hiccup 1.0.0-beta1 error

Question

I'm creating a compojure project using hiccup-1.0.0-beta1. I get the following stack trace when I run lein ring server-headless:

Caused by: java.lang.IllegalAccessError: defelem does not exist

at hiccup.page_helpers$eval17.invoke(page_helpers.clj:1)
at clojure.lang.Compiler.eval(Compiler.java:5424)

Which is confusing to me, because the file page_helpers.clj no longer exists in hiccup:

$ jar tf lib/hiccup-1.0.0-beta1.jar 
META-INF/MANIFEST.MF
META-INF/maven/hiccup/hiccup/pom.xml
META-INF/maven/hiccup/hiccup/pom.properties
project.clj
hiccup/compiler.clj
hiccup/core.clj
hiccup/def.clj
hiccup/element.clj
hiccup/form.clj
hiccup/middleware.clj
hiccup/page.clj
hiccup/util.clj
$ 

Also, my code doesn't even try to bring in page_helpers.clj:

(ns views.layout 
    (:require [app-config :as config])
    (:use hiccup.core)
    (:use hiccup.page)
    (:use hiccup.element))

I'm having the same trouble.

I think you are using dev-dependency lein-ring. If you look in to your project/lib/dev folder, you'll see hiccup 0.3.X jar there. It is because the file ring-devel jar file uses old hiccup. I guess the cause to the problem is to do with the conflicts between these files. But I haven't figured out a way to get around this yet.

However, if you use lein ring uberwar to create a deployable file, that file works in another container (eg. tomcat) just fine.
