Hi,

I’m facing a strange issue while sending request on a database table with WFS.

What I find out:

  • Removing the paging make it works but can send back unwanted features.
  • If I let the paging, it crashes
  • If I let the paging and manually add “sortBy” parameter in the WFS query, it seems to work.

I suspect the issue to be related to the database. The table does not contain a Primary Key. Maybe sorting depends on the primary key? Please find enclosed the Geoserver log and stacktrace.

The issue occurs in this class, at org.geotools.data.transform.TransformFeatureCollection.openIterator(TransformFeatureCollection.java:130)

https://github.com/geotools/geotools/blob/27.x/modules/extension/transform/src/main/java/org/geotools/data/transform/TransformFeatureCollection.java

Regards.
