This can't possibly be a limitation of Flex Builder can it?  I was having no problem until I got a new computer and installed the latest Flex Builder and imported my project.  Now I have no design mode for the project.  I do get design mode if I create a new project.  Has anyone else seen this issue?  I need help! ...

I'm sorry.  I'm new to Javascript and I was using the For...in construction incorrectly.  I was not properly referring to the individual layerInfos.  I got it working.  Sorry about that. ... View more

I've wondered the same thing.  Are there some experts or designers that have some input? My understanding of the difference between FeatureLayer and a DynamicMapServiceLayer is that the DMSL pulls in all the features (layers) within a map service and the FL only deals with one layer.  The FeatureLayer gives you much more control over the display of the graphics as well as giving you access to editing of features. ...

Thanks for your response lowgas! The link you posted points to the editor widget.  Since I'm not editing anything, I don't think this is what I'm looking for.  Should I not be using a feature layer if I'm not doing selection/editing?  If you have any more ideas about how to change the look of individual graphics in a feature layer based on their attributes, please let me know.  Otherwise, I will probably have to use the ClassBreaksRenderer and choose some arbitrary breaks. The other question I had was if it were possible to create a custom symbol.  Does anybody have any ideas or suggestions? ... View more

While I don't know enough about scope in Flex to know if this will work from your external buttons.mxml, I think I would use: myMap.addEventListener(MapMouseEvent.MAP_CLICK,mapClickHandler); Then you could put the reverse in the clickHandler for one of the other buttons: myMap.removeEventListener(MapMouseEvent.MAP_CLICK,mapClickHandler); ...

Thanks dpaddock! I didn't realize that polygons naturally supported multiple disjoint shapes.  I didn't understand what the rings were.  I added each ring from my selected polygons to a "master" polygon and used that as the geometry for the query!  This is exactly what I was looking for.  Thanks so much! ...

Thanks for the reply, dpaddock! Because of the simplicity of selecting, I thought it would be the answer to my dillema, but perhaps it isn't.  Is it possible to get the union of Polygons?  It looks like there is a union function for Extents, but since it returns an Extent, I assume it just returns the bounding box that contains both Extents, (which would include a lot more area than I want).  I was really hoping to use the geometry of disconnected polys in a query.  Is this even possible? ...

if you're not using ArcGIS 10, then the symbology from the map service isn't used.  You can set a default symbol by using the symbol attribute of the FeatureLayer, or you can use a custom Renderer to set different symbols for different attribute values (similar to Categories, Quantities, etc in ArcMap).  Here are some examples.  The second one is straight from http://help.arcgis.com/en/webapi/flex/samples/index.html <esri:FeatureLayer id="featureLayer" url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/0" }">   <esri:symbol>    <esri:SimpleMarkerSymbol color="0xFFFFFF" alpha="0.8" size="10" style="diamond">     <esri:outline>      <esri:SimpleLineSymbol color="0xFF0000" style="dash" />     </esri:outline>    </esri:SimpleMarkerSymbol>   </esri:symbol> </esri:FeatureLayer> <esri:FeatureLayer  outFields="[FIPS,POP2000]"                            url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/0">             <esri:renderer>                 <esri:ClassBreaksRenderer attribute="POP2000">                     <esri:ClassBreakInfo maxValue="61" symbol="{symbol1}"/>                     <esri:ClassBreakInfo maxValue="264"                                          minValue="62"                                          symbol="{symbol2}"/>                     <esri:ClassBreakInfo maxValue="759"                                          minValue="265"                                          symbol="{symbol3}"/>                     <esri:ClassBreakInfo maxValue="1900"                                          minValue="760"                                          symbol="{symbol4}"/>                     <esri:ClassBreakInfo minValue="1901" symbol="{symbol5}"/>                 </esri:ClassBreaksRenderer>             </esri:renderer>         </esri:FeatureLayer> ...

Thanks!  I might try that. ... View more

You could also set mouseChildren to false on the Graphic. Thanks for your response. I was trying to set mouseChildren on the Graphic, but I couldn't get access to it, since the graphicAdd event was never fired.  I don't know why this is.  The GraphicsLayer's dataProvider is a QueryTask, and when the query returns, the graphics get updated, but no graphicAdd events. ...
