[Qgis-developer] join table

[Siki Zoltan]

Dear QGIS DEvelopoers,

I'm writing a python plugin where I would like to handle the values in a dbf 
table which is joined to a shape file. I could join the table to the shape file 
using VectorLayer.addJoin, but I can't find any way to get the joined 
attributes of a feature. After joining the dataProvider.attributeIndexes 
returns only the original columns of the shape file. The fieldNameIndex returns 
-1 for all joined column names.
Any advice to get the values in joined columns in Python?

Thanks,
Zoltan
