[Gvsig_desarrolladores] Añadir campos a un shape y rellenar registros

[Ruth Sos Del Diego]

Hola de nuevo,

Como he comentado esta mañana necesito crear nuevos campos en una tabla de
un shape de mi vista.

Adjunto un código nuevo que me crea un campo nuevo y luego me abre la
tabla. La tabla me la abre, pero el campo no me lo crea. Alguien puede
decirme qué es lo que está mal???

Gracias de nuevo,

Ruth
