Hi,
features from a postgresql data base cannot be selected if there are null values in numeric fields.
 &lt;2026-03-05T08:53:42&gt; 	5468	Fusion Viewer	127.0.0.1	Administrator
 Error: Value for testfloat8 property is null.
 StackTrace:
  - MgRenderingServiceHandler.ProcessOperation() line 83 file C:\Workspace\mg-4.0\MgDev\Server\src\Services\Rendering\RenderingServiceHandler.cpp
  - MgOpQueryFeatures.Execute() line 125 file C:\Workspace\mg-4.0\MgDev\Server\src\Services\Rendering\OpQueryFeatures.cpp
  - MgServerRenderingService.QueryFeatures() line 1063 file C:\Workspace\mg-4.0\MgDev\Server\src\Services\Rendering\ServerRenderingService.cpp

  - MgServerFdoFeatureReader.GetDouble() line 440 file C:\Workspace\mg-4.0\MgDev\Server\src\Services\Feature\ServerFeatureReader.cpp	
this also happens for GetSingle(), GetInt32(), GetInt64() aso.
