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

[G. Allegri]

Probably I'm not using it correctly.
I want to retrieve the features within a bbox and obtain one field only.
Im' doing the following:

request
= QgsFeatureRequest(bbox).setSubestOfAttributes(['id'],mylayer.pendingFields())
for feat in mylayer.geFeatures(request):
   for fields in feat.fields():
       print field.name()

and I get all the field names printed while I thought I would get only 'id'.
What am I doing wrong?
