[Users] featureFilter in GeoExt.data.FeatureStore

[Christian Mayer]

Hi Sebastian,

I am not quite sure what's wrong here. Your code seems to be fine. As an 
alternative you could try to set the filter as a property of the protocol:

... proxy: new GeoExt.data.ProtocolProxy({

                          protocol: new OpenLayers.Protocol.WFS({

                              url: 
"http://gateway.hamburg.de/OGCFassade/Test_HH_WFS_Fachdaten.aspx",

version: "1.1.0",

                 featureType: "verkehr_parkhaeuser",

                 featureNS: "http://www.deegree.org/app",

srsName: "EPSG:25832",

*filter:**new OpenLayers.Filter.Comparison(...)*

                          }) ...


maybe it is a bug in GeoExt 1.1. I had no closer look in this at the 
momen. Let us know if you find a solution or a proof for a bug.

Best regards,
Chris
