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
