Description
- create a spatial DB table in POSTGIS and define a DB field as Integer type
- leave the field empty and publish that Featureclass as a WFS service (I used GeoServer 2.13.0)
- Open QGIS and connect to the WFS Service using version 2.0
- Load the FeatureClass in QGIS and visualize it (drag the FeatureClass to the layer pane)
- Use the identify tool and click on a feature with a NULL value for an integer property ("xsd:int")
- Look at the query result pane: The value shows 0 instead of NULL
- In the DescribeFeatureType response the integer property is listed as "<xsd:element maxOccurs="1" minOccurs="0" name="bundesland_id" nillable="true" type="xsd:int" />"
- In the DescribeFeatureType response the double property is listed as "<xsd:element maxOccurs="1" minOccurs="0" name="costs_deployment" nillable="true" type="xsd:double" />"
- Empty DOUBLE properties ("xsd:double") are shown correctly as NULL in Query Results pane
- In the resulting XML from the GetFeature request, all properties with NULL values are correctly suppressed as of WFS specification
- The FeatureClass is returned correctly from the WFS service when the Filter "<fes:PropertyIsNull>" on the integer field is used

Looks like a duplicate of https://issues.qgis.org/issues/18674 , which I can't replicate
Can you replicate your issue with QGIS dev ?
