Thank you Vinayan.
Based on your code, I was able to make it work like this:
new_attributes = layer.pendingFields()
for j in new_attributes:
if provider.defaultValue(j).isNull():
new_attributes[j] = feature.attributeMap()[j]
else:
new_attributes[j] = provider.defaultValue(j)
And I will try to use On Fly Reprojection too.
Thanks again,
Alexandre Neto
