[Gvsig_desarrolladores] Problema de refresco en ProjectTable (Bug gvSig??)

[Juanjo]

Hola a todos, 

A ver si logro explicarme.
Si cargamos una tabla desde base de datos, mediante el gestor de proyectos,
usando el driver Oracle. La tabla se carga correctamente en pantalla. Ahora
bien, si desconectamos momentaneamente la red, hacemos algo tan simple como
intentar cambiar el tamaño, o mover de sitio la tabla, gvSig devuelve un
java.null.pointer.Exception y se queda totalmente bloqueado. Si volvemos a
restablecer la conexion posteriormente sigue bloqueado y no para de lanzar
el error que he puesto abajo del mail. 
Si hacemos lo mismo con una vista en la que hemos cargado una capa, de la
misma base de datos, el error que aparece es un error del driver, y gvSig
reacciona nada más volver a establecer la conexión. 


¿¿Es distinto el driver utilizado para manejar capas de base de datos y
tablas??
¿¿Es un Bug de gvSig??
¿¿Hay alguna manera de solucionarlo??
