Have you put a crossdomain.xml file on your ArcGIS server? You can use a tool like Charles, Fiddler or the Firefox Add-on HttpFox to see if a request is being made for crossdomain.xml and failing. Also, if you're using the debug Flash Player, you should see a security error warning if this is the issue. ... View more

By default, the background is transparent. You can still use PNG if you turn the transparency off: http://resources.esri.com/help/9.3/arcgisserver/apis/flex/apiref/com/esri/ags/layers/ArcGISDynamicMapServiceLayer.html#imageTransparency ... View more

It is not required to be in the root of the web server. That's just where it looks for it by default. When the app initializes, the developer can make a call to Security.loadPolicyFile(). See: http://livedocs.adobe.com/flex/3/langref/flash/system/Security.html#loadPolicyFile() You'll still need to have a small crossdomain.xml file in the root of the web server that says it's OK to use policy files from other places on your server. This is called the master policy file. It would look like this: <?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd"> <cross-domain-policy>    <site-control permitted-cross-domain-policies="all"/> </cross-domain-policy> You can get more info on this at (page 7 and 11 of the pdf): http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html ...

Yes, you can control which symbol is used by setting the latestObservationRenderer to any of the out-of-the box renderers or by implementing your own renderer. Doc reference: http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/renderers/package-detail.html ... View more

Yes, this is similar to this sample: http://resources.esri.com/help/9.3/arcgisserver/apis/flex/samples/index.html?sample=GeoRSSApp You need to create Graphics with Geometries that you then add to a GraphicsLayer. ... View more

It doesn't matter where the features come from. You can replace the GPX feed with an RSS feed. The important thing in that sample is that the FeatureLayer is using a FeatureCollection with LayerDetails that has TimeInfo with a startTimeField. See the fLyr_initializeHandler() function. You can change the startTimeField to whatever attribute you'll be setting in the Graphics you create. If you're going to be tracking multiple trucks, you can set the trackIdField on the FeatureLayer to the attribute that identifies each truck. Attatched is another sample that gets the latest photos from Flickr every 10 seconds. ... View more

Try creating your FeatureSet like this: var featureSet:FeatureSet = new FeatureSet([event.graphic]); or this var featureSet:FeatureSet = new FeatureSet([ { geometry: event.graphic.geometry } ]); ... View more

It sounds like this is more than you need, but just in case, this sample shows how you can create custom tool tips where you can then show whatever you'd like: http://help.arcgis.com/en/webapi/flex/samples/index.html?sample=MapTips ... View more

I think you want to change the background of the Navigation component which extends VBox and is the slider's container. Try adding this and changing the values:     <mx:Style>         Navigation         {             backgroundAlpha: 0.5;             backgroundColor: #000000;         }     </mx:Style> ... View more
