You need to create your own grouping feature store type with:

var GroupingFeatureStore = Ext.extend(Ext.data.GroupingStore,
GeoExt.data.FeatureStoreMixin());

You can a store with something like that:

    var wea_store = new GroupingFeatureStore({
        fields: [{
            name: "Bez",
            type: "string"
        }, {
            name: "Standort",
            type: "string"
        }, {
            name: "Betreiber",
            type: "string"
        }],
        sortInfo: {field: 'Standort',direction: "ASC"},
        groupField: 'Standort',
        layer: layer_wea
    });
