[Users] Query Panel

[Francesc Cañas]

Hi,

I want to put a Query Panel to my map as the one in GeoEditor of Open Geo
Suite. I've found the gxp query panel but i don't know how it works. The
only change I've made is the layerStore where I've put my layerStore
mapPanel.layers.


<script src="http://gxp.opengeo.org/master/script/gxp.js"></script>




//**********************************************  Query Panel
 **************************

var queryPanel = new gxp.QueryPanel({
                title: "Query Panel",
               width: 300,
               bodyStyle: "padding: 10px",
                autoScroll: true,
                layerStore: mapPanel.layers,
                bbar: ["->",
                {
                  text: "Query",
                  handler: function () {
                    queryPanel.query();
                  }
                }],
                listeners: {
                  query: function (panel, store) {
                    wms.setVisibility(false);
                    var rule = new OpenLayers.Rule({
                      filter: panel.getFilter()
                    });
                    rule.symbolizer[queryPanel.symbolizerType] = symbolizer;
                    var style = new OpenLayers.Style("", {
                      rules: [rule]
                    });
                    wms.mergeNewParams({
                      sld_body: new OpenLayers.Format.SLD().write({
                      namedLayers: [{
                          name: panel.selectedLayer.get("name"),
                          userStyles: [style]
                        }]
                      })
                    });
                    store.bind(vecLayer, {
                      initDir: GeoExt.data.FeatureStore.STORE_TO_LAYER
                    });
                  }
                }
              });


But Firebugs says:

this.map is undefined
error source line:
gxp.js (línea 637)

...fieldLabel:this.layerText,store:this.layerStore,value:this.layerStore.getAt(0).g...



Thanks!
