Since your query gets tacked on to the URL, and browsers impose a limit on the size of URLs for security purposes, you'll need to configure a proxy page to get this to run successfully. More info here: Using the proxy page. The first bullet point on that page addresses your issue. I thought the same thing but when i test the Query through the ArcGIS Services Directory Query form it works and its all placed in the URL.

Hello, I am doing a large query and the esri js api is crashing on me.. I have tested my where clause in ArcMap and it works but its not working in the JS API because of its size / length (i believe) Below is a dump of my where clause SWISPIN IN ('18388911.-1-53.12','1824003.-1-99','18200012.-1-35.21','1824005.-1-53.2','1824005.-1-3','18348912.-1-51','18348912.-1-59.2','18348911.-1-23.2','1824005.-1-24','18240016.-1-8','FLAG','18388911.-1-36.11','18388910.-1-7.1','1824004.-1-10','FLAG','18240016.-1-21.1','1824003.-1-99','18240016.-1-23','1824003.-1-16.2','1824004.-1-23.2','1824001.-1-10.112','1824001.-1-10.12','FLAG','18428925.-1-28.2','1824004.-1-3.12','18240020.-1-98.21','1844002.-2-16.12','FLAG','FLAG','1824005.-1-6','1824005.-1-39.2','1824005.-1-13','1824003.-1-22','1824003.-1-128','1824002.-1-38','1824003.-1-100','1842899.17-1-3','1844001.-1-51','FLAG','18348910.-1-28.113','FLAG','18240013.-1-113.2','1824003.-1-6.2','1842898.-1-45','FLAG','1824005.-1-11.12','1824006.-1-60.2','1824004.-1-35','1832893.-1-13','1844001.-1-35','1824005.-1-144','18268915.-1-13.12','1842899.17-1-15','1838898.-1-8.12','18240014.-1-39','FLAG','FLAG','1824003.-1-110','1824001.-1-10.211','18348910.-1-24.2','1824005.-1-37','1824005.-1-52.2','18240016.-1-2','1824004.-1-9','18348912.-1-45','FLAG','1824005.-1-29.1','FLAG','1824004.-1-1.11','1824004.-1-11','FLAG','1824004.-1-19.1','1824005.-1-135','FLAG','1824005.-1-42.2','18348912.-1-65.1','FLAG','18440010.-1-9.111','18240017.-1-22','18240017.-1-16.121','1824006.-1-62.2','1824007.-1-94','1824003.-1-24','1824004.-1-27.2','1824005.-1-20','FLAG','18348910.-1-24.1','FLAG','18240020.-1-16','18348912.-1-66.111','18428925.-1-7','1824003.-1-109.1','1824005.-1-135','1844006.-1-19.2','1824003.-1-101','1824003.-1-101','18348912.-1-50.2','FLAG','18348911.-1-23.1','18240020.-2-51','18240020.-2-55.12','18348911.-1-22','1824004.-1-7','18368919.-1-22.2','18388911.-1-49.12','18240014.-1-40.1','18240017.-1-16.121','1824005.-1-22.1','1824005.-1-36.12','1844001.-1-49','1824006.-1-60.1','1824003.-1-16.1','1826896.-1-59','1824003.-1-109.2','18348910.-1-15.2','18240019.-1-42','FLAG','FLAG','1824005.-1-36.2','1824005.-1-36.114','1844001.-1-40','1824003.-1-129','18428925.-1-28.2','1824004.-1-20.1','FLAG','FLAG','1824002.-1-29.1','1824005.-1-2','FLAG','1824005.-1-9.12','1824002.-1-34','1824003.-1-25.1','FLAG','1824003.-1-93','18348912.-1-59.112','1824005.-1-52.12','1844001.-1-50','18348912.-1-52','1824005.-1-29.2','18348911.-1-21','1824006.-1-8','1824005.-1-137','1824003.-1-27','18440012.-1-25.1','1824005.-1-12.1','18200012.-1-48','18240016.-1-19.2','1842898.-1-52','FLAG','FLAG','1824004.-1-36','1824006.-1-12.2','1824006.-1-56','FLAG','1824002.-1-37','1824003.-1-102','1824005.-1-17.2','1824002.-1-28.2','18388910.-1-5.1','1824003.-1-15','18388911.-1-50.2','18348911.-1-17','18348910.-1-23','18368931.-1-108.12') Yes its long, but its really only 165 properties. According to Firebug and my own debugging the query is not even being sent to the server, it dies on execute() but works when I use a small length where clause. Right now i get a "Type error: io is undefined" error from the ESRI JS file. Is there a limit on the where clause length? Drew

I am able to pull all the panels and toolbars out to a second monitor already using ArcGIS Desktop 9.3.1.

Hi All, I am wondering about the feasibility of creating a single 'Recycle Bin' button that could be placed in the header area and it would clear absolutely all graphics or selected items with a single click on its icon in the header bar. Thanks! This is quite easy.. Here are the steps and code needed (replace this.map with your map component) - Loop thought all the map layers and find the all the graphics layers (code below) [php] /** * Get all the graphics layers inside the map */ public function GetAllGraphicLayers():ArrayCollection { var graphicsLayers:ArrayCollection = new ArrayCollection(); for each(var layer:Layer in this.map.layers) { if (layer is GraphicsLayer) { graphicsLayers.addItem(layer); } } return graphicsLayers; } [/php] Then loop through all the graphic layers and clear.. [php] public function ClearAll():void { var graphicLayers:ArrayCollection = GetAllGraphicLayers(); for each(var grapicsLayer:GraphicsLayer in graphicLayers) { grapicsLayer.clear(); } } [/php] You could combine all the code i guess but i have it broken out for other reasons. Drew

Tyrone, I have used the same code on 9.3, 9.3.1 and 10 without any problems.. Have you examined the params being sent to the server using Firebug? You might find your error digging down there.. Drew

‎10-22-2010

I am running ESRI Flex API .1.2 on a AGS 10 server, so 9.3.1 should not be a problem.. I would "check your paramaters" 🙂 Here is a code dump of an identify params I am using that works against a 9.3.1 and 10 AGS map service this._identifyParams = new IdentifyParameters(); this._identifyParams.layerOption = this.layerOption; this._identifyParams.returnGeometry = true; this._identifyParams.layerIds = Application.application.tocContainerControl.toc.GetVisibleLayerIDsInScaleRange(); this._identifyParams.tolerance = 3; this._identifyParams.width = this._map.width; this._identifyParams.height = this._map.height; this._identifyParams.geometry = point; this._identifyParams.mapExtent = this._map.extent; this._identifyParams.spatialReference = this._map.spatialReference; If i had to guess your probably missing the spatial reference param.

Using the same map service consumed in ArcMap i get the 436k result. I don't know what the right answer is, but i just wanted to say that ArcMap returns the same as the Geometry Service. Drew

‎10-20-2010

Matt, Could it be because your "map point" is just an X,Y and not an envelope? When using an point as the geometry you have to be very accurate when clicking on the map so the query can find the feature:) You might want to convert the point to an envelope/extent then expand(..) it a little. I am not 100% sure this is your problem, but from a quick glance at the code it looks like it. Drew

‎10-20-2010

I don�??t believe that�??s possible. You need a �??complete�?� event handler. You could have a helper function that would fill the combo box.. Sample (works) private function fillComboBoxWithData(cmb:ComboBox, displayFieldName:String, featureSet:FeatureSet):void { var results:ArrayCollection = new ArrayCollection(); for each (var graphic:Graphic in featureSet.features) { var fieldValue:String = graphic.attributes[displayFieldName].toString(); results.addItem({label: fieldValue, data:graphic}); } cmb.labelField = "label"; cmb.dataProvider = results; } Drew

Pvitt, You can set the vertical align programatically using the below code. myHBox.setStyle("verticalAlign","middle"); You can learn more about setStyle() here http://livedocs.adobe.com/flex/3/html/help.html?content=styles_08.html Drew

Thanks for the assistance everyone. I ended up going with the FeatureLayer to get the information i needed. I don't think it's the easiest way, but it works.... I would like to see the info come in when the AGSDynamicLayer gets loaded, ArcIMS did that. I am still looking for better ways if someone else can point me in the right direction. I feel that I am missing something obvious..... Anyways.. here is my javascript code to get feature layer information (i.e field names and types) The GetFeatureLayerInfo function does the work, the other is just sample code to test. [php] function TestFeatureLayerInfo(map, serviceURL, layerID) { GetFeatureLayerInfo(map, serviceURL, layerID, function (featureLayerInfo) { alert("ObjectID Field: " + featureLayerInfo.objectIdField); var fieldInfos = ""; for (var i = 0; i < featureLayerInfo.fields.length; i++) { var field = featureLayerInfo.fields; fieldInfos += field.name + "\t=\t" + field.type + "\n"; } alert("Fields: " + fieldInfos); }); } function GetFeatureLayerInfo(map, serviceURL, layerID, callbackFunction) { var featureLayerURL = serviceURL + "/" + layerID; var featureLayer = new esri.layers.FeatureLayer(featureLayerURL, { mode: esri.layers.FeatureLayer.MODE_SELECTION }); var layerAddResult_connect = dojo.connect(map, "onLayerAddResult", function (featureLayerInfo) { map.removeLayer(featureLayer); dojo.disconnect(layerAddResult_connect); if (callbackFunction != null) { callbackFunction(featureLayerInfo); } }); map.addLayer(featureLayer); } [/php] Drew

Can you post your repeater code?

‎10-14-2010

After testing the "FeatureLayer" functionality this morning i realized that its not what i need. Its more for overlaying the data. Isn't there a way I can get the Fields and their data types from a specific feature class using the JS API? Drew

Here is a sample that shows how to get the item. Take a look at the code "doQuery(event...)" and see how to get the repeater index then get that item from your array. <?xml version="1.0" encoding="utf-8"?> <s:Application name="Repeater Test" xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" xmlns:esri="http://www.esri.com/2008/ags"> <fx:Script> <![CDATA[ import com.esri.ags.events.QueryEvent; import mx.controls.Alert; import mx.states.State; private function doQuery(event:Event):void { var state:String = arrList.getItemAt(event.currentTarget.repeaterIndex).toString(); var where:String = "STATE_NAME = '"+state+"'"; query.where = where; query.outFields = ["STATE_NAME"]; queryTask.addEventListener(QueryEvent.EXECUTE_COMPLETE, onQueryComplete); queryTask.execute(query); } private function onQueryComplete(result:QueryEvent):void { //Alert.show("done"); } ]]> </fx:Script> <fx:Declarations> <s:ArrayList id="arrList" source="[New York,California,Florida]"/> <esri:QueryTask useAMF="false" id="queryTask" showBusyCursor="true" url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/5"/> <esri:Query id="query" outSpatialReference="{myMap.spatialReference}" returnGeometry="true"/> </fx:Declarations> <esri:Map id="myMap"> <esri:extent> <esri:Extent xmin="-14298000" ymin="2748000" xmax="-6815000" ymax="7117000"> <esri:SpatialReference wkid="102100"/> </esri:Extent> </esri:extent> <esri:ArcGISTiledMapServiceLayer url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Physical_Map/MapServer"/> <esri:GraphicsLayer id="myGraphicsLayer" graphicProvider="{queryTask.executeLastResult.features}"/> </esri:Map> <s:VGroup horizontalCenter="0" verticalCenter="0"> <mx:HBox> <mx:Repeater id="rpt" dataProvider="{arrList}"> <s:Button click="doQuery(event)" left="20" top="335" label="{rpt.currentItem}" /> </mx:Repeater> </mx:HBox> </s:VGroup> </s:Application> Drew
