Hello ,

We noticed a problem with an ogc:filter getMap request. ( GeoServer 2.24.2 )

It is only if you have a Within Filter without another extra filter option.

So what is wrong:

FILTER=

<ogc:Filter xmlns:gml=http://www.opengis.net/gml
xmlns:ogc=http://www.opengis.net/ogc><ogc:Within><ogc:PropertyName>geom</ogc
:PropertyName><gml:Polygon

154852
464024</gml:posList></gml:LinearRing></gml:exterior></gml:Polygon></ogc:With
in></ogc:Filter>

This url gives an error in geoserver ( Rendering process failed. Layers:
geonovation:energielabels_amersfoort -> Caused by:
java.lang.NullPointerException at
org.geotools.filter.spatial.ReprojectingFilterVisitor$GeometryFilterTransfor
mer.transform(ReprojectingFilterVisitor.java:437)

 

 

But when I have the following URL, with added on ogc:And and a random extra
filter ( in this case 0>=0), then it is working OK!

What could be the problem here?
