Now, on your project, why can't we see the layers we select on the map, just on the legend? Also, for that to work do I have to have that legendskin.mxml? 1 - on your project - are you talk about this sample http://web.zone.ee/bespiva/legendwithskin/ ??? [/HR] 2 - why can't we see the layers we select on the map - hmmmmmmmm just zoom to some big city (LA, NY, ...) and you'll see all streets, parks ... you turn on in TOC. Some sublayers are empty (no map features), but layer is visible and has all needed information to be shown in legend [/HR] 3 - do I have to have that legendskin.mxml? - IMHO skin is just a skin ~ collection of rules+styles by which the element/component is drawn, so if you need to change smthing in legend visualization - yes the better way to change skin. Skin is used in my sample, because default esri legend skin has some bugs P.S. Anatomy of a skin class (Adobe help with samples)

TypeError: Error #1009: Cannot access a property or method of a null object reference comes from this part of code queryTask.executeLastResult.attributes it does not matter where you use this code in ColumnChart tag <mx:ColumnChart id="columnChart"
dataProvider="{queryTask.executeLastResult.attributes}"
visible="{queryTask.executeLastResult != null}">
</mx:ColumnChart> or in script tag function queryOnClick():void
{
/** execute your query, then add the following: */
columnChart.dataProvider = queryTask.executeLastResult.attributes;
if(queryTast.executeLastResult != null)
{
columnChart.visible = true;
}else{
columnChart.visible = false;
}
} If the queryTask is never executed, then queryTask.executeLastResult is null!!! So queryTask.executeLastResult.attributes returns TypeError: Error #1009: Cannot access a property or method of a null object reference example / rule var myAnyTypeObject:* = null;
var somePr:* = myAnyTypeObject.someproperty; // returns TypeError: Error #1009: Cannot access a property ...
myAnyTypeObject.executeSomeFunction();// returns TypeError: Error #1009: Cannot access ... method ... Right? I would suggest to take Ben's code with some changes function queryOnClick():void
{
if(queryTask.executeLastResult != null)
{
columnChart.dataProvider = queryTask.executeLastResult.attributes;
columnChart.visible = true;
}else{
columnChart.visible = false;
}
}

From REST API help GPMultiValue Note that support for the GPMultiValue parameter type was added at 10 The fully-qualified data type for a GPMultiValue parameter is GPMultiValue:<memberDataType>, where memberDataType is one of the data types defined above. For ex. GPMultiValue:GPString, GPMultiValue:GPLong, etc. Note that at 10.0 only GPMultiValue:GPString data type is supported From 10.1 onwards all GP data types will be supported in a GPMultiValue. The parameter value for GPMultiValue data types is a JSON array. Each element in this array is of the data type as defined by the memberDataType suffix of the fully-qualified GPMultiValue data type name. Example 1: GPMultiValue:GPString data type ["Parcels", "Street Lights"] Example 2: GPMultiValue:GPLinearUnit data type: [ { "distance" : 345.67, "units" : "esriMiles" }, { "distance" : 36, "units" : "esriMiles" } ] via Geoprocessing task you can - Send a request to the server to execute a synchronous geoprocessing task. - Submit a job request to the server to execute an asynchronous geoprocessing task. I think input parameters are: var inputParams:Object = new Object();
inputParams.in_feature1 = "string type parameter"; // GPString = String
inputParams.in_featureliste = ["Red", "Green", "Blue"]; // GPMultiValue:GPString = Array
// yourGPTask.execute(inputParams); // - synchronous
// yourGPTask.submitJob(inputParams, new AsyncResponder(resultfunctionname, faultfunctionname ...)); // - asynchronous

---> find skin in downloaded ArcGIS API for FLEX \arcgis_api_for_flex_3_0\ArcGIS_Flex\skins\src\com\esri\ags\skins\AttributeInspectorSkin.mxml ---> include skin in to your project (rename if needed) ---> add skinClass attribute to your ispector with reference to included skin ...
<esri:AttributeInspector id="attributeInspector"
visible="false"
includeInLayout="false"
skinClass="ee.alphagis.assets.skins.MyAttributeInspectorSkin"
... ---> in skin find <mx:Form> tag <!--- Form to display the attributes of the active feature. -->
<mx:Form id="form"
width="100%" height="100%"
enabled.disabled="false"
horizontalScrollPolicy="off"
maxHeight="{hostComponent.getStyle('formMaxHeight')}"
verticalScrollPolicy="auto"> ---> configure form layout NB! examples you looked for for example: <!--- Form to display the attributes of the active feature. -->
<mx:Form id="form"
labelWidth="100"
... ---> other way is work (need some dev. exp.) with Fields used in attribute inspector: DoubleField IntegerField StringField ... and others in same package you can extend them, skin them, also create own fields ...

I can't find a remove function too, but ESRI Viewer is extandable application you can extend WidgetTemplate.as as you want (this code is just a sample - not tested)
// Viewer version is 2.5
public function addTitlebarButton(btnIcon:String, btnTip:String, btnFunction:Function, selectable:Boolean = true):void
{
var btn:TitlebarButton = new TitlebarButton();
btn.callback = btnFunction;
btn.selectable = selectable;
btn.source = btnIcon;
btn.toolTip = btnTip;
if (selectable)
{
btn.addEventListener(MouseEvent.CLICK, titlebarButton_clickHandler);
if (headerToolGroup.numElements == 0)
{
selectedTitlebarButtonIndex = 0; // automatically select the first button added
}
}
headerToolGroup.addElement(btn);
}
public function removeTitlebarButton(item:TitlebarButton):Boolean
{
var success:Boolean = false;
// next logic is the same as in headerToolGroup.removeElement(...)
if (item != null)
{
try
{
var buttonIndex:int = headerToolGroup.getElementIndex(item);
if (buttonIndex > -1)
{
headerToolGroup.removeElementAt(buttonIndex);
success = true;
}
}
catch (error:ArgumentError) // child element not exists in headerToolGroup
{
trace(error.getStackTrace());
}
}
return success;
}
