I opened a project that was done by a Developer before. For the index.mxml, it shows such an error: Could not resolve <s:Application> to a component implementation on Line 10 (in red below): <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:shp="com.esri.shp.*" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" initialize="initCollections();" xmlns:esri="http://www.esri.com/2008/ags" applicationComplete="application1_applicationCompleteHandler(event)" creationComplete="application1_creationCompleteHandler(event)" > ...... protected function application1_creationCompleteHandler(event:FlexEvent):void { addEventListener(KeyboardEvent.KEY_DOWN, deleteKeyHandler); } I could not figure out what kind of problem it is.

In my thread at http://forums.arcgis.com/threads/63288-Map-switch-as-scale-change, I requested how to auto-switch basemap as scale change.  Mr. Robert, the author (also the best ArcGIS Flex expert as I know) of the eMapSwitch, provided me the solution.  It works if I make the scale change using the Scalebar to zoom-in. In one of my application, when a feature (e.g. a parcel) is found and then the map is zoommed-in the parcel.  The scale is changed to 1:1128 (the smallest scale),  but the basemap is on the default one US Areial that does not have the map at this scale.  How can the auto-switch basemap also work on this senario?  Another question is how auto-switch to for zoom-out with the default basemap. Thanks. ... View more

I want to adjust the column width of an IdentifyWidget.  Currently, the Key and Value columns have the equal width.  I revised the popUpRenderSkin.mxml:         <s:Group id="keyValueGroup" width="100%">             <s:layout>                 <s:ConstraintLayout id="keyValueGroupLayout">                     <s:constraintColumns>                         <s:ConstraintColumn id="col1" width="30%" />                         <s:ConstraintColumn id="col2" width="70%"/>                     </s:constraintColumns>                 </s:ConstraintLayout>             </s:layout>         </s:Group> However, the column widths of both columns have no change.  Did I do something incorrect?  Thanks. ...
