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

Hi list,
I have got an Ext.grid.GridPanel using a Geoext.data.FeatureStore as
its store. The store uses a GeoExt.data.ProtocolProxy to get features
from a WFS. On that store I set the featureFilter-configOption in
order to only display (and request) a subset of the available features
in the grid (for instance only those within a given geometry, or with
a specific id; for now, I am working with a simple comparison filter).
However, the filter is not getting evaluated and all features are
requested and show up in the grid. I would be very glad, if someone
could point me to what I am missing.
Here is the code for the grid panel:
gridPanel = new Ext.grid.GridPanel({
ref: 'featuregrid',
title: 'Tabellenansicht Parkhäuser',
region: 'north',
height: 200,
sm: new GeoExt.grid.FeatureSelectionModel(),
store: new GeoExt.data.FeatureStore({
fields: [
{name: "name", type: "string"},
{name: "art", type: "string"},
{name: "frei", type: "string"},
{name: "received", type: "string"}
],
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"
})
}),
featureFilter: new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.EQUAL_TO,
property: "name",
value: "Alsterhaus"
}),
autoLoad: true
}),
columns: [
{header: "name", dataIndex: "name"},
{header: "Art", dataIndex: "art"},
{header: "Freie Stellplätze", dataIndex: "frei"},
{header: "Aktualität", dataIndex: "received"}
]
});
You can also find an online-version at

<http://geoportal-hamburg.de/verkehr2-dev/index2.html> (the above
code is in app.js)
Best regards and thanks already,
Sebastian
