Problema en algunas situaciones para devolver nulo en BeanShell #267

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Estas líneas:

Entity messageHandler = entity("Mensajes de combate");
String theMessage = messageHandler.getMessage( messageName , arguments );
return theMessage;

Funcionan bien. Sin embargo, si lo ponemos así: 

Entity messageHandler = entity("Mensajes de combate");
return messageHandler.getMessage( messageName , arguments );

(al menos) cuando getMessage (implementado en beanshell directamente en la 
entidad) devuelve null, obtenemos este error interno del intérprete de 
beanshell:

bsh.InterpreterError: null fromValue

El porqué es un misterio.
