I'm trying to read a SpatiaLite table with a Primary Key Unique ID (PKUID) field, made in QGIS. All the fields of the SpatiaLite table can be read, except for this PKUID field. Even an AttributeExposer does not do the trick. Is there a reason for this?

 

 

For the moment, I created a workaround: I read the table, together with the spatial data, in a SpatiaLite reader. Then I read the same table in an SQLite reader, which can detect the PKUID field, but does not contain the spatial data. A FeatureMerger does the rest.
