[Gvsig_english] WFS layer attributes bug

[Jorge Piera Llodrá]

Hello.

I remember that we had problems writing GML files that have space characters (' ') in the field names because XML doesn't support a space in the name of a tag. If you export a file to GML the space character is replaced by a configurable escape character ('_' by default). The problem was that there is not an option to change this escape character using the user interface (only by code is possible)

I'm having a look to the source code and in the reading process '_' is replaced by ' '. The solution is just add an option to gvSIG to change this escape character or just not change the escape character in the reading process. We will fix it in next release.

If you are a developer, you can change this escape character. Have a look to the class org.gvsig.gpe.xml.XmlProperties (libGPE-XML)

Regards,
Jorge.

Yes I'm sure. If you add a WFS layer containing unederscored
attributes to your vista, make it visible and you
go to the Filer tab of the WFS attributes panel (reachable via the
menu that appears right-clicking on the selected layer),
you can see that underscored attributes are displayed correctly but
when you click on one of them to see
 the known values, they aren't loaded.
Oppositely, if you click on non-underscored attributes you will see
all known values.
I think it is a problem that occurs when creating
theSelectableDataSource associated to the WFS layer...

In fact, when you read the field names of the layer you will see that
underscored attributes contain white spaces.
Use the following lines for example:
              SelectableDataSource sds = wfsLayer.getRecordset();
              ReadableVectorial rv = wfsLayer.getSource();
		
               // Desde el modelo se debería acceder a los campos y
sus valores cargados
	      for (int i = 0; i < sds.getFieldCount(); i++) {
		     String fieldName = sds.getFieldName(i);
                       .....
              }
