 * Revision 1.12  2006-10-02 09:09:45  jorpiell

 * Cambios del 10 copiados al head

 *

 * Revision 1.10.2.3  2006/09/29 14:12:53  luisw2

 * CRSFactory.getCRS substitutes ProjectionPool.get

 *

 * Revision 1.10.2.2  2006/09/28 08:54:01  jorpiell

 * Ya se puede reproyectar

 *

 * Revision 1.10.2.1  2006/09/26 07:36:24  jorpiell

 * El WFS no reproyectaba porque no se le asignaba a la capa un sistema de referencia. Ahora ya se hace.

 *

 * Revision 1.10  2006/09/05 15:41:52  jorpiell

 * A?adida la funcionalidad de cargar WFS desde el cat?logo

 *

 * Revision 1.9  2006/07/05 12:05:41  jorpiell

 * Se ha modificado para que avise si se han recuperado las mismas features que marca el campo buffer

 *

 * Revision 1.8  2006/06/21 12:52:10  jorpiell

 * A?adido un icono para la capa WFS

 *

 * Revision 1.7  2006/06/21 12:35:45  jorpiell

 * Se ha a?adido la ventana de propiedades. Esto implica a?adir listeners por todos los paneles. Adem?s no se muestra la geomatr?a en la lista de atributos y se muestran ?nicamnete los que se van a descargar

 *

 * Revision 1.6  2006/06/15 11:17:06  jorpiell

 * Se ha encontrado la forma de comprobar cuando se prodicia un error de parseo al hacer un hasnext (en la feature). Se atrapa y se lanza la excepci?n hacia arriba

 *

 * Revision 1.5  2006/06/14 07:57:19  jorpiell

 * Ya no se usa la estrategia ni se usa geotools para hacer el getFeature. Ahora se usa ?nicamente para el parseo de GML

 *

 * Revision 1.4  2006/06/05 16:49:31  caballero

 * poder editar y exportar

 *

 * Revision 1.3  2006/05/25 10:31:55  jorpiell

 * Se ha renombrado la clase WFSFields por WFSAttributes porque era algo confusa

 *

 * Revision 1.2  2006/05/23 13:21:59  jorpiell

 * Si hay alg?n problema en la carga se muestra un mensaje de error

 *

 * Revision 1.1  2006/05/19 12:54:11  jorpiell
