 * $Log$

 * Revision 1.19  2007-09-19 16:14:50  jaume

 * removed unnecessary imports

 *

 * Revision 1.18  2007/03/15 13:34:16  ppiqueras

 * Eliminado mensaje de aviso no necesario.

 *

 * Revision 1.17  2007/03/05 13:49:42  ppiqueras

 * Si una capa WFS no tiene campos (y por tanto no tiene un campo obligatorio de tipo geometr?a), que avise al usuario y no permita que se intente cargar dicha capa.

 *

 * Revision 1.16  2007/02/22 12:25:09  ppiqueras

 * A?adidas tool tip text.

 *

 * Revision 1.15  2007/02/09 14:12:39  jorpiell

 * Soporte para WFS 1.1 y WFS-T

 *

 * Revision 1.14  2007/02/07 13:26:23  ppiqueras

 * Corregido bug: al seleccionar una feature, pero sin cerrar el di?logo, se retrocede y se conecta a otro servidor,  se manten?a la posici?n seleccionada en la tabla de features. Se ha solucionado haciendo que se quede deseleccionada toda la tabla de features.

 *

 * Revision 1.13  2007/01/23 13:12:43  ppiqueras

 * Corregido un peque?o bug: el ?rea de texto del nombre de la feature no debe ser editable, dado que si se edita no procesa el texto escrito.

 *

 * Revision 1.12  2007/01/15 14:16:22  ppiqueras

 * Corregido bug: no cargaba los campos al principio y adem?s se ejecutaba m?s de una vez.

 * Revision 1.11  2006/12/15 13:57:34  ppiqueras

 * eliminado un import que sobraba

 *

 * Revision 1.10  2006/12/12 10:24:45  ppiqueras

 * Nueva funcionalidad: Pulsando doble 'click' sobre una capa de un servidor, se carga (igual que antes), pero adem?s se avanza a la siguiente pesta?a sin tener que pulsar el bot?n 'Siguiente'.

 *

 * Revision 1.9  2006/12/04 08:59:47  ppiqueras

 * Algunos bugs corregidos. A cambio hay 2 bugs relacionados que todav?a no han sido corregidos (ver PHPCollab) (los tiene asignados Jorge).

 *

 * Revision 1.8  2006/10/27 06:44:56  jorpiell

 * Se han cambiado algunas etiquetas de texto que sal?an recortadas

 *

 * Revision 1.7  2006/07/21 11:50:31  jaume

 * improved appearance

 *

 * Revision 1.6  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 1.5  2006/05/25 10:31:06  jorpiell

 * Como ha cambiado la forma de mostrar las capas (una tabla, en lugar de una lista), los paneles han tenido que ser modificados

 *

 * Revision 1.4  2006/05/23 08:09:39  jorpiell

 * Se ha cambiado la forma en la que se leian los valores seleccionados en los paneles y se ha cambiado el comportamiento de los botones

 *

 * Revision 1.3  2006/05/19 12:57:08  jorpiell

 * Modificados algunos paneles

 *

 * Revision 1.2  2006/04/20 16:38:24  jorpiell

 * Ahora mismo ya se puede hacer un getCapabilities y un getDescribeType de la capa seleccionada para ver los atributos a dibujar. Queda implementar el panel de opciones y hacer el getFeature().
