Bug report #20603
QGIS interprets wfs integer value NULL as '0'
|Category:||Web Services clients/WFS|
|Affected QGIS version:||3.4.1||Regression?:||No|

Using qgis 3.4.1, when displaying attributes of type INT via WFS 1.1.0 (Geoserver), NULL values is displayed as "0". WFS does not transmit nodes with null values in GML, and qgis should not interpret these as "0". This issue was produced both in qgis 2.18.25 (LTS) and 3.4.1 on different machines here. This issue references #18674, which was closed as not replicable.
