Description
I have a spatialite DB with tables, they work fine in Qgis.
If I create a view:
CREATE VIEW vmapdata AS SELECT * from mapdata
and add a row to geometry_columns (identical to the row for table mapdata) then I can load the view as a layer in Qgis, and it plots it. I can use the query tool and get attribute values in the popup dialog but if I get the whole attribute table it is full of "ERROR" values.

If I do that to create my view, I don't see the view in qgis.
Qgis seems to ignore the "GIS layer Authorization" options set in Spatial-gui and shows anything with a listing in geometry_columns. It doesn't show the spatial view I just created according to the guidelines, I guess because that has its geometry specified in views_geometry_columns.
This is with 1.3.0-Mimas - has the spatialite provider been updated to fix this?
This one is not at all a bug: it's an attempt to force
spatialite beyond it's specific architectural limits.
Spatial Views are fully supported in spatialite-2.4.0,
but you are required to follow the guide-lines you can
