Hi Bob. I didn't resolve this issue. The combo box can start with a <null> value, but once an actual value has been selected, you can't go back to <null>. I expect to migrate our applications to Javascript very soon and hope that this issue will be addressed. In the meantime, it hasn't really been a problem, since those fields really should have non-null values anyway. ... View more

Dasa, Could you elaborate on including a WMS layer in the Operational Layers section of the config.xml file for Flex Viewer 2.2? The documentation does not have much detail. Specifically, I am attempting to add the hypsography layer from the Toporama Web Map Service (Toporama WMS) of the Earth Sciences Sector (ESS) at Natural Resources Canada (NRCan). See http://geogratis.cgdi.gc.ca/geogratis/en/service/toporama.html for information about this service. <Layer queryable="0" opaque="0" cascaded="0"> <Name>hypsography</Name> <Title>Hypsography</Title> - <Abstract> The Hypsography layer represents elevation points and continuous lines formed by peaks of equal altitude used to describe the topography. Elevation of points and lines is always calculated from mean sea level. </Abstract> <SRS>EPSG:4269</SRS> The layer line I have included in my config.xml is as follows: <layer label="Contours" type="wms" visible="true" visiblelayers="hypsography" url="http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en"/> Is there an option to set the WMS version in the layer line? An error message I get seems to indicate that FlexViewer defaults to version 1.3.0, but Toporama supports the OGC WMS standard, version 1.1.1.

This is not mentioned in the documentation. I suppose that "EPSG:900913 - Google Spheric Mercator", which is supported by Toporama, would match the ArcGIS Online cached services. ... View more

Dave, I have modified your code to allow for configuration from the EditWidget XML configuration file. Add the following to EditWidget.xml: <editablelayer> <layername>Sample Layer</layername> <fieldnames>FIELD1,FIELD2</fieldnames> <fieldlabels>Field1,Field2</fieldlabels> <hiddenfields>FIELD3</hiddenfields> </editablelayer> Within the EditWidget.mxml file: [Bindable] private var showAttributesText:String; /* MODIFICATION -- setup variables for FieldInspector values from configXML */ private var editableLayerName:String; private var editableLayerFieldNames:Array; private var editableLayerFieldLabels:Array; private var editableLayerHiddenFields:Array; /* MODIFICATION --  END */ private function basewidget_widgetConfigLoaded(event:Event):void { // hide map infowindow if any map.infoWindow.hide(); if (configXML) {     // MODIFICATION --  load configuration values for FieldInspector into variables   editableLayerName = configXML.editablelayer.layername;

Thanks, Dave. Your code sample is very helpful 🙂 ... View more

Xiaoyi Zhang, I'm trying to return the attributes to their original order, too, but I haven't been successful so far. It may be worth noting that the attributeInspector property of public class Editor is read-only (i.e. we can 'get' editor.attributeInspector, but we can not 'set' it). The public class AttributeInspector allows us to 'set' properties such as formItemsOrder. We can see that in action in the example at http://help.arcgis.com/en/webapi/flex/samples/index.html?sample=AttributeInspectorInfoWindowEditable I'm not sure how to apply the sample code to the ArcGIS Viewer for Flex 2.1. ...

Are there plans to add support for EPSG 3857 to version 9.3.1, perhaps as an alias to 102100, or is the move to version 10 going to be the only way to have support for EPSG 3857? ... View more
