Error description

• Using Decision Engine, when dealing with a list of Long (or
  Integer, Float) that is returned by a method such as
  public List<Long> listWrapperLongMethod()
  
  The BRL rule below
     definitions
         set 'a Long' to a number in 'test
  input'.listWrapperLongMethod() ;
     if
         true
     then
         print "Long list method: " + 'a Long' ;
  
  is translated in ARL as follows:
     rule `Long list method` {
       ilog.rules.business_name = "Long list method"
       ilog.rules.dt = ""
       ilog.rules.package_name = ""
       status = "new"
       when {
         sample.Test() from $EngineData.this.test_input;
         `a Long` : java.lang.Double() in
  $EngineData.this.test_input.listWrapperLongMethod();
         evaluate ( true);
       }
       then {
         ilog.rules.brl.System.printMessage("Long list method: " +
  `a Long`);
       }
     }
  
  and the rule is not executed.
