[Zoo-discuss] BufferPy problem

Thu Dec 20 12:52:15 PST 2012

Hi everyone,

this http-Post buffer request [1] (BufferPy, buffers around features
from layer topp:tasmania_water_bodies, 7 features) works.
If I change the layer to topp:states (49 features) the request doesn't
work [2]. You find the error message here [3].
If I buffer just one feature from the states layer the request works
[4]. Every single feature works.

I've noticed this behavior in other layers. One feature works the
whole layer doesn't work.
It looks like that the request from a certain number of objects does
not work anymore.

What's wrong?

I appreciate any advice.

Regards,
Farkas
