 Hi,
 
 just as the title. 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
