Just to say, the following query gives me the correct result:
entities = mymodel.all().order('myId').fetch(300)
keys = {}
while entities:
for obj in entities:
if obj.myId in keys.keys():
keys[obj.myId] = keys[obj.myId] + 1
else:
keys[obj.myId] = 1
entities = mymodel.all().order('myId').filter('myId >', entities
[-1].myId).fetch(300)
So why does the key-based query not work?
