[Qgis-developer] QgsFeatureRequest.setSubestOfAttributes(etc.) return all the fields

[G. Allegri]

It seems that joining filters do not work (at leat in Python). I have to do:

request = QgsFeatureRequest(bbox)
request = request.setSubestOfAttributes(['id'],mylayer.pendingFields())

And I see that field names are always returned but field values are set to
None if filtered out.
