[Gvsig_desarrolladores] Error en la carga de archivos CML

[Francisco José Ferreiro Viñas]

Hola.

Estoy desarrollando un plugin en gvSIG cuyo cometido será la carga de
varias capas automáticamente nada más iniciar gvSIG. Como hará uso de
servicios WMS me he fijado en la exportación e importación de capas
mediante archivos CML.

Puedo exportar una capa WMS sin problemas y guardarla como CML. Pego a
continuación un ejemplo.

El problema viene a la hora de cargar este archivo. Usando gvSIG desktop,
versión 2.1.0.2227 testing, yendo por la opción del menú Archivo - Abrir
WMC, salta una excepción NullPointerException. Pego a continuación la traza
completa

Este problema ocurre en las versiones 2.1.0-2225 y 2.1.0-2227, la más
reciente. ¿Tiene alguna solución?

Gracias.
