[Users] FeatureStore - too many features

[Sarah Schuessler]

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 : 

    http://dev.openlayers.org/releases/OpenLayers-2.10/examples/filter.html

  Regards,

Alexandre
