I have an application that when I click identify, it looks at all layers in the map (over multiple services) and returns the results from all those services/layers. I'm having strange behavior though, with one service. It's returning duplicate values. The other 3 services in the map all return correctly. The services are all 9.3.1 services, and they are a mix of tiled and dynamic. The idResults.length equals 6 when it should equal 3. Any idea what could be going on? Code (thanks to http://forums.arcgis.com/threads/31757-Multiple-services-in-Identify-javascript-API?highlight=identify+multiple) is below. Thanks.function executeIdentify (loadedServices, evt) { dojo.forEach(loadedServices, function(service) { if (service.visibleLayers.length > 0) { expected_callback_counter++; //every visible layer should produce a callback, even if no results } } ); //for each loaded non-base layer service dojo.forEach(loadedServices, function(service) { //get service object if (service.visibleLayers.length > 0 && service.visible) { //does service have visible layers? //showLoading(); url = service.url; //get url of service identifyTask = new esri.tasks.IdentifyTask(url); //ceate new identify task identifyParams.layerIds = service.visibleLayers; //set layers to identify identifyTask.execute(identifyParams, function(idResults) { //callback function - fires for each visible layer if (idResults.length > 0) { dojo.forEach(idResults, function(result) { allResults.push(result); } ); } callback_counter++; //a callback has fired - count them if (callback_counter === expected_callback_counter) { if (allResults.length > 0) { //may have no results across all services var content = ""; var currentLayerName; for (var index = 0; index < allResults.length; index++) { content += "<b>" + htmlEncode(allResults[index].layerName) + "</b><br>" content += "<table>"; for (var member in allResults[index].feature.attributes) { content += "<tr><td>" + htmlEncode(member) + ":</td><td>" + htmlEncode(allResults[index].feature.attributes[member]) + "</td></tr>"; } content += "</table><br>"; } var resultText; if (allResults.length === 1) { resultText = " Feature Identified"; } else { resultText = " Features Identified"; } map.infoWindow.setTitle(allResults.length + resultText); map.infoWindow.setContent(content); map.infoWindow.resize(320, 250); map.infoWindow.show(evt.screenPoint, map.getInfoWindowAnchor(evt.screenPoint)); } else { alert('No results found!'); } } }, //error callback function(err) {console.log("doIdentify: (" + err.name + ") " + err.message);} ) } } ) };
