Hello, Is there a way to read the extent from a map and set it (in lat/lon with projection?) For example: <esri:Map id="myMap" width="100%" height="100%" mapClick="mapClickHandler(event)"       timeSlider="{myFirstTimeSlider}"       openHandCursorVisible="false" wrapAround180="true">     <esri:Extent id="initExent" xmin="-10854962" ymin="4514317" xmax="-10779136" ymax="4572944">      <esri:SpatialReference wkid="102100"/>     </esri:extent>          <esri:ArcGISDynamicMapServiceLayer id="myDynamicService"               fault="myDynamicService_faultHandler(event)"               load="myTimeLayer_loadHandler(event)"               loadError="myDynamicService_loadErrorHandler(event)"/>       <esri:GraphicsLayer id="clickGraphicsLayer"/>      </esri:Map> Here, instead of the below codes, that specifies the value for the extent (some number): <esri:Extent id="initExent" xmin="-10854962" ymin="4514317" xmax="-10779136" ymax="4572944">      <esri:SpatialReference wkid="102100"/>     </esri:extent> Can I read from the map that I'm loading? Maybe like: myDynamicService.initialExtent.xmin, myDynamicService.initialExtent.xmax, etc...?? The extent for my map is set in lat/lon values, and so the projection also needs to be set. I don't know how to do this, because when I tried, at this time the values are 0. <esri:Extent id="initExent" xmin="{myDynamicService.initialExtent.xmin}" ymin="{myDynamicService.initialExtent.ymin}" xmax="{myDynamicService.initialExtent.xmax}" ymax="{myDynamicService.initialExtent.}">      <esri:SpatialReference wkid="{myDynamicService.spatialReference}"/>     </esri:extent> Please help! thank you!! ...

I am so new, trying to learn the basics of flex!! I am not sure how the <fx:script> blocks work when there are more than one?! In my case, the script block within a control has no knowledge of the anything else outside of it!!! For example, the codes below... Please look toward the end at function "protected function pubMapThumb_clickHandler(event:MouseEvent):void". Within this function, I could not access anything "outside", like the "pubmapList" or any functions in the main <fx:script> block. Can someone explain that to me, and how would I achieve in doing that? (access "outside" controls). Thanks so much!!!

Hello, I am a total newbie. I downloaded the Flex Api along with the samples (arcgis_api_for_flex_2_5). I followed the instructions in the readme, but when running, I get a bunch of errors (one for each mxml). Adobe AIR application is missing the corresponding ArcGISWebMap-app.xml. ArcGISWebMap.mxml /FlexSample/src Unknown AIR application.xml Problem .... The same error for each mxml. There is only one xml in the project, in which was created when I create the project. The samples only provided mxml files. Please help. Thank you. ---- This is the instruction in the readme: ======================= ArcGIS API for Flex 2.5 build date 2011-11-30 ======================= This file contains the ArcGIS Flex API Library (the swc file), skins and sample code. =============== Getting Started =============== 1. In Adobe Flash Builder, create a new Flex project (File -> New -> Flex project). 2. Copy all the contents of the ArcGIS_Flex\samples\src folder to src folder of the Flex project created above. 3. In Adobe Flash Builder, add the API Library to the project through Project -> Properties -> Flex Build Path -> Library Path -> Add SWC (and locate the "agslib-2.5-2011-11-30.swc") 4. In Adobe Flash Builder, right-click on any of the sample mxml applications and click "Set as Default Application". 5. In Adobe Flash Builder, right-click on any of the sample mxml applications and click "Run Application". ... View more
