[Qgis-user] join table

[Siki Zoltan]

Dear QGIS Users,

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
