My Decision expression is :#{true}, and the exception is :rg.jbpm.api.JbpmException: expression '#{true}' in decision 'decision' returned java.lang.Boolean instead of a transitionName (String): true   i reviewed the sourccode , in the line 51, there is a if , if ( (result!=null)          && (! (result instanceof String))        ) throw .....   does it mean the return must be a String ?   if that  is true , why there is a  transitionName = (String) result in line 56 -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529035#529035
