Is the problem when the function is being called? It should work as you've written it, but the function will only be called once unless the function takes a bindable argument, in which case it'd be called whenever the binding on the argument is triggered. ... View more

The Viewer doesn't support wms services yet. (The API does as of 2.1.) You can try using their ArcGIS REST service here instead: http://services.azgs.az.gov/arcgis/rest/services/OneGeology/AZGS_Arizona_Geology/MapServer You'll need to use a proxy though since they don't have a cross domain policy file at: http://services.azgs.az.gov/crossdomain.xml ...

I'm not familiar with the 1.3 code, but I'd start by using a tool like HttpFox to carefully compare the REST requests. ... View more

Here's a modification of the BufferSample at: http://help.arcgis.com/en/webapi/flex/samples/index.html?sample=BufferSample I've fixed the myGeometryService url and changed the base layer to a 4326 service. An example of the requests it sends is: http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer/buffer?unionResults=false&f=json&bufferSR=102100&geometries=%7B%22geometryType%22%3A%22esriGeometryPoint%22%2C%22geometries%22%3A%5B%7B%22x%22%3A%2D114%2E51800371679786%2C%22y%22%3A33%2E55105676332971%7D%5D%7D&unit=9036&distances=50%2C100&inSR=4326 <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"                xmlns:s="library://ns.adobe.com/flex/spark"                xmlns:mx="library://ns.adobe.com/flex/mx"                xmlns:esri="http://www.esri.com/2008/ags"                pageTitle="Buffer using the Geometry Service">     <!--          This sample creates buffers around the center of the map.

Yes, that's defined by the inSR REST parameter. The Flex API's BufferParameters doesn't have a property for this since the GeometryService gets it automatically from the first geometry in the geometries Array. Can you use a tool like HttpFox to verify if the inSR is being sent correctly in the REST request? ... View more

When you click on a result in the table, is it not panning and zooming the map to that feature? That's what I'm seeing in the sample. ... View more

Correct, this is not currently supported. ... View more

Not in onDemand mode since it only queries for features within the current extent so there's no way to know what the extent is of all the features matching the new definition expression. I'd stick with snapshot mode and then you can zoom to the extent of the features in the graphicProvider after updateEnd. ... View more

Did you try to change the width and height in SplashWidget.xml? The default is:     <width>375</width>     <height>375</height> ... View more

Try setting bufferSpatialReference to 102100 if you want to use Web Mercator and the outSpatialReference to 4326. Note from: http://sampleserver3.arcgisonline.com/ArcGIS/SDK/REST/buffer.html Note that when the bufferSR is GCS: Points and Multipoints: if unit is linear such as feet or meters, geodesic buffering is performed. Polylines and Polygons: unit must be angular such as decimal degrees for buffering to be performed. ... View more

Have you tried setting the bufferSpatialReference on your BufferParameters? http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/tasks/supportClasses/BufferParameters.html#bufferSpatialReference ... View more

The spatial reference of NGS_Topo_US_2D is 4326 so you'll need to update the initial extent to also be in 4326 values. Also make sure that all your other tiled layers are also in 4326 since they can not be re-projected. ... View more

Yes, the initial extent should be in the same spatial reference as the first base layer. ... View more
