Greetings. This is a continuation of the origional post "Really Close a Widget" (http://forums.esri.com/thread.asp?c=158&f=2421&t=302669). Great stuff. However there are a few conceptual leaps required by the solution that I am not yet equiped to make. The Solution: public function closeWidget(id:Number, url:String):void       {        if (widgetTable.containsKey(id))        {         var widget0:IBaseWidget = widgetTable.find(id) as IBaseWidget;         var wObj0:DisplayObject = widget0 as DisplayObject;         widgetTable.remove(id);         if(widgetBox.contains(wObj0))          widgetBox.removeChild(wObj0);        }                      if (moduleTable.containsKey(url))        {         var modInfo:IModuleInfo = moduleTable.find(url) as IModuleInfo;         moduleTable.remove(url);         modInfo.unload();        }        } Conceptual Leaps: 1. Where does this funciton belong. 2. How do you reference the widgetTable and moduleTable 3. How do you reference the widgetBox. I realize that this is probably pretty complex to explain so any more hints to get me in the right direction will be greatly appreciated. ViewerContainer.dispatchEvent(new AppEvent(AppEvent.WIDGET_CHANGE_STATE, {id: this.widgetId, state:WidgetStates.WIDGET_CLOSED})); is not the appropriate way to close the widget if you wish to reloas the config file.

Greetings Everyone,              I am working on updating our site for version 2.2 and am missing the external links menu from the previous version. Has anyone worked out a good way to handle multiple external links in the FlexViewer 2.2? Thansk,  Tyler Wairing ... View more

Greetings Everyone,           I am working on a tool to save projects or sessions in the Flex Viewer application. I am pretty close at this point but I am having a problem with the tiled and dynamic map services overlaying incorrectly.           When I load the map settings for each different session, the dynamic layers do not initially overlay the tiled layers correctly. The tiled layers are always significantly offset from the dynamic layers (notice how the building footprints and stereets do not overlay the ortho photo proprely). When I reload the session the second time however, everything aligns correctly. This leaves me to believe that I am calling a method out of order when a tiled layer is turned on. I have included my code below and attached a graphic of the misaligned dynamic and tiled layers. Does anyone recognize any errors?  Thanks, Tyler Waring   public function loadSavedSession(session:Object):void    {     SiteContainer.addEventListener(AppEvent.SAVED_SESSION_APPLIED, SavedSearchCleanUpSteps)         //get service and layer visability from the session object     var strAllFinalVisibleServicesAndArrays:String = session.strVisLayers;

Greetings Everyone, I have been struggling to figure out how to perform a spatial test on a graphics layer and a featureset.  What I am trying to do is extend the graphical search functionality in the search widget so that a user can press the ???A??? key and add additional features to both the graphics layer and the RecordData class object. I have figured the main functions for this extension but now I am finding that if the added features overlap the existing graphics layer then duplicates will be produced in both the graphics layer and the RecordData class object. To overcome this problem, I would like to use compare the existing in map graphicslayer to the new featureset that is produced when an additional graphical query is made. I think I am looking to use a GeometryService.relation method with the spatialRelationship parameter set to SPATIAL_REL_RELATION. However I have no Idea how to set up the comparisonString. I???ve tried to jump into the Shape Comparison Language documentation but I must admit that it is completely over my head. I have tried my best to generate the correct parameters but I am obviously doing something wrong. Here is what I???ve got: myGeometryService.relation(compareArray1, compareArray2,GeometryService.SPATIAL_REL_RELATION,"compareArray1 != compareArray2") The Error I get whilst running this method is: [FaultEvent fault=[RPC Fault faultString="Object reference not set to an instance of an object." faultCode="500" faultDetail="Unable to perform the relation operation"] messageId=null type="fault" bubbles=false cancelable=true eventPhase=2]      Does anyone know what I may be doing wrong?

Greetings. I am working on implementing design patterns in my customizations of the Simple Flex Viewer and future customizations of the new Viewer for Flex 2.0. What design patterns were used to develop both of these flex viewers? Thanks,  Tyler ... View more

Greetings everyone,  The shift zoom functionality is disappearing after using setMapAction().  Here is a scaled back version of a search tool that I am having a problem with. I must be missing something simple. Any ideas?
