Muhammad,    Do you get a graphic drawn on the screen when you do the initial search? The error you are getting is that it can not get the polygon geometry's first ring. ... View more

Jayme,    From initial glace the first issue is <dropdown>African boxthorn, Prickly pear, Spear thistle, Aleppo pine</dropdown> Should be <dropdown>African boxthorn,Prickly pear,Spear thistle,Aleppo pine</dropdown> Notice no spaces between commas. I will keep digging if that is not it. ... View more

Stuart,    Is that not the exact same image that is in the overviewmapwidget? Because it should be exactly the same. ... View more

Mohamed,     You really need to start doing some reading. Code snippets will do little good for a manager if you don't understand what is happening in the code. Start looking here http://resources.esri.com/help/9.3/arcgisserver/apis/flex/help/content/getting_started.htm and then read this about the crossdomain.xml http://resources.esri.com/help/9.3/arcgisserver/apis/flex/help/content/deploy_application.htm ...

Mohamed,    All you need to do to add your own data is go to your REST Services directory http://localhost/ArcGIS/rest/services/ and see a listing a map services that you have available and click on one and copy the url from the address bar and paste that into on of the samples. Here is one of ESRI's map services: http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer Here is an example of what one on your server would look like: http://localhost/ArcGIS/rest/services/mydata/MapServer So using the most simple sample from the link I provided you the code example would look something like this <?xml version="1.0" encoding="utf-8"?> <mx:Application     xmlns:mx="http://www.adobe.com/2006/mxml"     xmlns:esri="http://www.esri.com/2008/ags"     pageTitle="Example - ArcGIS API for Flex connecting to a dynamic AGS service">     <esri:Map>         <esri:ArcGISDynamicMapServiceLayer             url="http://localhost/ArcGIS/rest/services/myData/MapServer"/>     </esri:Map> </mx:Application> ...

Stuart,    You need to get the debugger version of flash player so you can put a break point in the code as I mention in the previous post. I don't have a clue what is wrong on your end as I just took the two files and added it to another SFV project and it ran perfectly again. ... View more

mei 09,    So what is the design and workflow of your app that you would need to get all of the water catchments and their hydrological features at the same time?... This can be done using the GeometryService Relation method. You will have to run two queries on to return all the water catchments and then another to return all the hydrological features so that you can feed them into the GeometryService.Relation method. The results of the Relation will have values like "geometry1Index = 999 and geometry2Index = 0" which means that the geometry in the first array with the id of 999 meet the relation requirement that you specified in relation to the geometry in array 2 with the id of geometry2Index of 0. ...

Brad,    So the best way to get the values for your initial and full extent is to go to your REST Services Directory Page at http://ngnv-jhqj6-a014/ArcGIS/rest/services and choose the map service that has your most preferred data extent and there you will see values listed for initial and full extent. The overview widget needs to be set to use one of your map services that is in UTM in it's OverviewMapWidget.xml file. The second option is to add the extent and spatial reference to the OverviewMapWidget.mxml manually as in this example   <esri:Map id="map" units="{Units.FEET}">    <esri:extent>     <esri:Extent xmin="661140" ymin="-1420246" xmax="3015668" ymax="1594451">      <esri:SpatialReference wkid="26777"/> <!-- NAD_1927_StatePlane_Kansas_North_FIPS_1501 -->     </esri:Extent>    </esri:extent>    <esri:ArcGISDynamicMapServiceLayer url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer"/>    <esri:ArcGISDynamicMapServiceLayer url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Petroleum/KGS_OilGasFields_Kansas/MapServer"/>   </esri:Map> ...

francesco,    Positioning of the scalebar and the zoom slide can be done through CSS but as you are just beginning and was not aware of this I doubt that this is your case. It would be best for you to post your flex code so we can see why yours are not in the default location. ... View more
