[xwiki-devs] xwiki syntax 2.0 error when using xe 1.6 snapshot

Hi, I use the xe made from svnroot/xwiki/enterprise/, and create a page using "xwiki 2.0". put only one line in the content "abc", then save and review. Got error as following: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'getRenderedContent' in class com.xpn.xwiki.api.Document threw exception java.lang.NoSuchMethodError: org.xwiki.rendering.renderer.xhtml.XHTMLRenderer.<init>(Ljava/io/Writer;Lorg/xwiki/rendering/DocumentManager;)V @ /templates/contentview.vm[7,7] Any suggestion? Thanks Wang Ning
