[gdal-dev] Layer.GetNextFeature() does not seem to get the next feature (Python 2.7.2, GDAL1.9.2

[David Verbyla]

I have a layer of 15 polygons from a shapefile.  I can access the features
using Layer.GetFeature(i),
but not using Layer.GetNextFeature().

For example:
>>> polyFeature = pondsLayer.GetFeature(0)
>>> print polyFeature.GetFID()
0
>>> polyFeature = pondsLayer.GetFeature(1)
>>> print polyFeature.GetFID()
1

>>> polyFeature = pondsLayer.GetFeature(0)
>>> print polyFeature.GetFID()
0
>>> polyFeature = pondsLayer.GetNextFeature()
>>> print polyFeature.GetFID()
Traceback (most recent call last):
  File "<pyshell#23>", line 1, in <module>
    print polyFeature.GetFID()
AttributeError: 'NoneType' object has no attribute 'GetFID'

Any suggestions?

Thanks.
