hi all

i am getting the following error when using a in an event.

20:04:02,418 ERROR [GraphElement] action threw exception: couldn't get value for file 'classes/java/lang/bsh.class'

<process-state name='Sub Process'>
 <event type='node-enter'>
 <script name='node-enter'>
 System.out.println("---------------node-enter");
 </script>
 </event>

i read the docs and the bsh.jar file is in the classpath including the jboss common/lib.

any help is most appreciated
