Hi Alexandre,
thank you.
That wfs BBOX thing worked. But not combining FeatureStore with this wfs. I
need
a proxy and read that I have to include including ext-override-ajax.js into
GeoExt build file for GeoExt recognizing my OpenLayers proxy. But that did not
work.What went wrong?
Why did including including ext-override-ajax.js not working?
Thanks!
best regards
Sarah

Hello Sarah,
Yes, you could define a BBOX filter in your WFS protocol to fetch just a
portion of the features you want. See an example of BBOX filtering :

Alexandre
