Thank you for your response. I think I tried to implement what you were suggesting below. Could you have a look? One thing that bothers me is having to use the URL. You see, the queryFeatures method, according to the documentation, will try to use a client side request if it can...will it still do that if I give it a URL?? I mean, how could it since this is a new FeatureLayer constructed from a URL. It really seems that I need the maps FeatureLayer to make a query that would work on the client only.
function FindFeaturesInCurrentExtent(outFields, layerToQuery) {
//var outFields = "FacilityID";
//var layerToQuery = "Transformer";
var esriMap = this.app.map; //a reference the esri.Map object
for (var i = 0; i < esriMap.layerIds.length; i++) {
var ly = esriMap.getLayer(i.toString());
if (ly instanceof esri.layers.ArcGISDynamicMapServiceLayer) {
var adms = ly;
for (var j = 0; j < adms.layerInfos.length; j++) {
var li = adms.layerInfos;
if (li.name == layerToQuery) {
var url = adms.url + "/" + li.id;
var fl = new esri.layers.FeatureLayer(url, {
outFields: [outFields]
});
var ext = this.app.map.extent;
var query = new esri.tasks.Query();
query.geometry = ext;
//Ideally this will be a client-side request
fl.queryFeatures(query, function (response) {
alert(response.features.length.toString()); //Correctly returns the number of features
});
}
}
}
}
};
