I am embedding a WAB Dev Ed application into a customers content management system web page and the customer has a requirement to send an attribute of a clicked feature back to the content management system. The obvious solution would be to configure a link/button in the callout configuration within the web map to execute some logic, but this is not allowed and any javascript calls are filtered out of the web map. The next approach could be to use feature actions at the WAB level, which would provide a means to execute a javascript function but by default these are not obvious or easily accessible from the callout (click ellipsis to show context menu, select appropriate feature action). Is it possible to include a call to a feature action from a button/link created in the callout? If so, how? Alternatively, can a feature action be added as a link to the callout footer, like the "zoom to" link? If so, how? Can the callout footer be customised to include a javascript function call with an attribute of the selected feature as a parameter? Thanks ... View more

Using ArcGIS Enterprise 10.6.1, I have created an SOE that performs connected/upstream/downstream traces against a Geometric Network. This works in most cases. When  the start point is on an certain set of edges, the trace crashes the ArcSOC.exe process for the service. The AGS log reports the following stack trace: java.lang.Exception: Could not service request. at com.esri.arcgis.discovery.admin.rediscovery.actors.RediscoveryAppServer.handleRequest(RediscoveryAppServer.java:539) at com.esri.discovery.DiscoveryService.handleRequest(DiscoveryService.java:112) at com.esri.client.AGSRequest.handleRequest(AGSRequest.java:216) at com.esri.client.ServiceClient.handleRequest(ServiceClient.java:110) at com.esri.client.exts.ExtensionClient.handleRequest(ExtensionClient.java:189) at com.esri.client.app.exts.ExtensionHandler$2.doOperation(ExtensionHandler.java:205) at com.esri.client.app.templates.OperationTemplate.execute(OperationTemplate.java:119) at com.esri.client.app.exts.ExtensionHandler.handleOperation(ExtensionHandler.java:268) at com.esri.client.app.exts.ExtensionHandler.extensions(ExtensionHandler.java:94) at com.esri.client.app.exts.ExtensionHandler.service(ExtensionHandler.java:83) at com.esri.rf.RServlet.service(RServlet.java:121) at javax.servlet.http.HttpServlet.service(HttpServlet.java:742) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:231) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:199) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:96) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:496) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:140) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:81) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:87) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:342) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:803) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:790) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1459) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:748)  When I debug the source, it actually crashes on the call to perform the trace, traceFlowSolver.FindFlowElements(pFlowMethod, esriFlowElements.esriFEJunctionsAndEdges, out _junctionIEDs, out _edgeEIDs); This line has try catch statements around it but the ArcSOC still just crashes with no caught exceptions. I am able to trace through these edges if I start on another edge, i.e. start on a downstream edge with an upstream trace. Note: the tracing does work on most network edges, it just fails on some and that subset of failing edges is persistent. I have tried to investigate for a data issue or a GN issue through ArcMap. I have found that if I display direction arrows, the edge features that cause the crash do not get a direction arrows and "The spatial references do not match" errors appear for them. My data frame is set to Web Mercator (3857), to match the base maps my client wishes to use, whilst the source data is stored in MGA Zone 56 (28356), so I tried setting my data frame to MGA Zone 56 and all the direction arrows appear with no errors. So I published my service with the spatial reference set to MGA Zone 56, but the SOC process still crashes for the same edges. I can't seem to debug any further. Can anyone give me any clues as to either what may be causing the SOCs to crash or how I could debug further? ... View more

I have created an MXD that has a layer with a couple of label classes with a label expression. The expression takes the first character of the domain description using the mid function (vbscript) to form a label. I can confirm the Display coded value description box is checked for the label expression. In ArcMap 10.5.1 the label appears correctly, with the first letter of the domain description. I share the MXD with ArcGIS Server 10.5.1. The same label in the dynamic map service renders the the first character of the domain code, not the description. Query requests against the same feature in the same service return to domain description.There are no errors in the ArcGIS Server logs. My data is source from a SQL Server geodatabase (saw a similar post with no answer indicating that SQL Server may be an issue). Is this a bug? or am I doing something wrong? ... View more

I am building a custom WAB widget that selects features from a third party SOE across a number of predefined layers. I am trying to use the SelectionManager to present the highlighted features on the map and the associated selected records in the attribute table. Reference information about the SelectionManager is scant and I have been using the Select widget to see how I can implement it. I have the code mostly working except that the highlighted features are not appearing on the map, they are however being selected in the attribute table. I am using selectionManager.setSelection method passing in the appropriate layerObject, obtained from the appropriate layerInfo from the webmap and an array of Graphic objects for the selected features and these features definitely exist in the layer passed. The service containing the selection layer is a dynamic map service, not a feature service, but the Select tool works fine on this service. I can't see any code in the Select widget to add the graphic objects to the map, so I assume the SelectionManager handles that, is this correct? Does anyone have any ideas as to what I might be doing wrong? ... View more
