Hi, Is there a way to get the extent of a FeatureLayer (with all its features not only the ones on the map)? Regards.

I tried using attributes['SHAPE.LEN'] and it doesn't work for me.

Thank you for the answer 🙂 In my code I do as in the sample. I add drawTool.activate(DrawTool.EXTENT) in the "Mouse Down" event handler. But the first time that I perform a mouse down on the map (after the map is loaded), the drawTool doesn't work. It works only after that first time. Furthermore, I have to dispatch a Mouse Up event in order to prevent the pan from happening.

Anyone who's tryed to create a selection by rectangle?

Hi, I have a feature layer used in a client flex application. The feature layer is used to publish a feature class that has many attributes. Among those attributes there is one named "color". As its name indicates, this attribute contains the color that of the feature. This attribute (color) is meant to be modified by the user. The symbology of the feature layer is set by a renderer created on the MXML file. I'd like to be able to set the color of each graphic of the feature layer, from its color attribute. Is it possible to tell the mxml renderer to set the color of its symbol to the value contained in the color attributes? I'd like to do that on the mxml side without using ActionScript. Regards.

Hello, I'm trying to draw a rectangle on the map using the DrawTool component. I want to start drawing directly after performing a Ctrl + MouseDown. So in the map_mouseDownHandler function I put the following code: if(event.ctrlKey){ // Activate the drawTool _context.drawTool.activate(DrawTool.EXTENT); // This one seems to be necessary in order to deactivate map pan _context.mapRef.dispatchEvent(new MouseEvent(MouseEvent.MOUSE_UP)); } But this dosn't work correctly a 100%. After the loading of the map, and only after the loading, It's necessary to perform a Ctrl + MouseDown and then perform a second MouseDown to be able to draw. After this, a Ctrl + MouseDown suffises to start drawing. Do you have any idea about where the problem could be? Regards.

Reprojecting my database is not possible because I do many spatial calculation on the web client side. Those calculations are not precise when done in Web Mercator. I guess I will have to find another basemap 😕 Thanks Robert.

Thanks Robert 🙂 I tryed using ArcGISDynamicLayer but the delay to display the layer was inacceptable at all!! Is there a way to improve that delay? I was thinking about saving the cache of the ArcGIS Online layer and then reproject the cache. Is that possible?

Hi, I have a map with a coordinates system different from the Web Mercator. I want to use ArcGIS Online layers on that map. Is there a way to do so? Thanks.

Could you elaborate on how it is technically impossible ? I managed to republish a dynamic map service from an ArcGIS Online service: - I created an MXD - I set the projection of the group layer to the projection I want - I added an ArcGIS Online map service to the group layer - Then I published the MXD as a map service and it worked just fine (as dynamic map service) But then when I tryed to create a cache from that service, it seems that the tiles were not "georeferenced(?)" correctly : The coordinate system of the tiles seems to have been changed to the one of the MXD, but the coordinates themselves weren't reprojected. => When I try to go to the location (x,y), I don't get the correct location. PS: I know you said this is illegal, but I'm trying to understand how map services work in this case. I'm not going to use this method.

‎05-03-2013

Ok thanks. Is it technically or legally impossible?

Hi, I'd like to use ArcGIS Online basemaps but not is the Web Mercator projection. Because of that I want to know if it's possible to reproject and republish them in a Map Service. => Is it possible to recover ArcGIS Online tiles of a zone, then reproject and republish them in a Map Service?

Hi, I have a map that uses ArcGIS Online in the small scales. So my map needs to be in Web Mercator in small scales. In the big scales, my web client Flex application uses some feature and map services to do some area and distance calculations. So my map needs absolutely to be in Lambert93, in the big scales, because geometric calculations in Web Mercator are not accurate at all. => I need to change the map spatial reference when I move from big/small scales to small/big scales. Is there a way to change the spatial reference of a map? Regards.

Hi, I have a cached map service that has a cache different from what its MXD contains. The MXD is used just to publish the map service. The cache wasn't generated by me: I don't have the data. So the service uses the cache (not the MXD) to publish the map. I consume the map service using <esri:ArcGISDynamicMapServiceLayer /> and it works. I'm a little confused. ArcGISDynamicMapServiceLayer is not supposed to read from the cache of the service! Only ArcGISTiledMapServiceLayer are supposed to be able to read from the cache. Why do I get the cached data on the map instead of the MXD data (which is different from the cache)? Regards.

Hi, I'm planning to loop on one QueryTask object to perform requests on multiple layers : at each iteration of the loop change the QueryTask url and send a request to one feature layer. There will be one callback function for the QueryTask object that will process all server responses. Is there any weird behaviour that could take place with this logic? What if two (or more) concurrent server responses are sent to the callback function? Are they all going to be processed or only one? Thanks 🙂
