[Qgis-developer] Pyqgis - join a CSV to a vector layer

[Martin Dobias]

Hi Michael

your code works for me. Maybe you have not added the loaded DBF to the
QgsMapLayerRegistry before using it for the join? The main layer
otherwise does not have a way to resolve the reference to layer from
its ID.

By the way, it is not necessary to set "joinFieldIndex" and
"targetFieldIndex" members - they will have no effect.

Regards
Martin
