OGR Shapefile DS requires ds.Destroy() to comit attribute changes (Python)

[crschmidt]

From within Python, with GDAL 1.4.0, I attempted to use the following code to commit a feature change to disk:

import ogr
ds = ogr.Open("TRAINS_ARC.shp", True)
l = ds.GetLayer(0)
f = l.GetFeature(1)
print f.GetFieldAsString(3)
f.SetField(3, "Ctps")
l.SetFeature(f)
l.SyncToDisk()

I placed this in a script (test.py), and ran it as:

python test.py

When I ran it multiple times, the field output did not change.

If I modified the file to add a "ds.Destroy()" to the end of it, the attribute value was changed.

I believe that I am using the 'standard' old-style Python bindings.

The data I attempted this on is available inside the (self-extracting zipfile)  ftp://data.massgis.state.ma.us/pub/shape/state/trains_shp.exe .
