      Dear all,

      I have followed the livetrails at http://labs.jboss.com/file-access/default/members/jbossrules/freezone/livetrails/credit_dsl_viewlet_swf.html but i'm stuck.

      I get this error:

      Exception in thread "main" java.lang.IllegalArgumentException: Unable to use expander. Make sure a expander or dsl config is being passed to the parser. [ExpanderResolver was not set].
