[Users] Geoext search?

Sun Feb 14 16:30:16 CET 2010

Hi Bart, I would really appreciate any help with this!
Below is the code, for the simplicity of it, it is all in one HTML. You only
have to have Geoext locally...
Javascript is directly copied from GeoExt API example:
http://www.geoext.org/lib/GeoExt/widgets/form/SearchAction.html
When I run this, Firefox error console says:

Errora: Ext.form.Panel is not a constructor
Source file: http://localhost/search_test/search-form.html
Line: 18

---search_test.html-----
<html>
    <head>
        <script type="text/javascript" src="
http://extjs.cachefly.net/builds/ext-cdn-771.js"></script>
        <link rel="stylesheet" type="text/css" href="
http://extjs.cachefly.net/ext-2.2.1/resources/css/ext-all.css" />
        <link rel="stylesheet" type="text/css" href="

        <script src="http://openlayers.org/api/2.8/OpenLayers.js"></script>
        <script type="text/javascript"
src="/GeoExt/script/GeoExt.js"></script>
<script type="text/javascript">
var formPanel = new Ext.form.Panel({
    renderTo: "formpanel",
    items: [{
        xtype: "textfield",
        name: "name__like",
        value: "mont"
    }, {
        xtype: "textfield",
        name: "elevation__ge",
        value: "2000"
    }]
});

var searchAction = new GeoExt.form.SearchAction(formPanel.getForm(), {
    protocol: new OpenLayers.Protocol.WFS({
        url: "http://publicus.opengeo.org/geoserver/wfs",
        featureType: "tasmania_roads",
        featureNS: "http://www.openplans.org/topp"
    }),
    abortPrevious: true
});

formPanel.getForm().doAction(searchAction, {
    callback: function(response) {
        // response.features includes the features read
        // from the server through the protocol
    }
});
 </script>
            </head>
    <body>

        <div id="formpanel" style="float:left;"></div>

    </body>
</html>
