An SQL View can be configured to have spaces in the Attributes names.
WFS DescribeFeatureType call fails with a java.lang.NullPointerException on such layers.
To reproduce, create an SQL View with aliases and spaces names:
SELECT prop1 AS "Prop with spaces", geom from my_table;
Publish it and just do a DescribeFeatureType on it
http://192.168.1.69:80/geoserver/wfs?&SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&TYPENAME
=it.geosolutions%3Atest_view
This is the response:
<ows:ExceptionReport xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ows="http://www.opengis.net/ows"

<ows:Exception exceptionCode="NoApplicableCode">
<ows:ExceptionText>java.lang.NullPointerException</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>
And this is the GeoServer log:

I know that attributes names should be no-colon-name, can WFS just ignore (and don’t output) the invalid ones?
