Didier Bastogne Posted May 27, 2021 Share Posted May 27, 2021 Hi, I do have a custom c# plugin which was developped (and is working fine with Spotfire Analyst 7.11) but today I started the migration to Spotfire Analyst 10.10 and I do get a weird issue. using the CustomDataSource in a CustomTool it works fine but when I use the same CustomDatasource via the Data/Add Data menu and choose my CustomDataSource I get this error after the prompt Dialog has been closed InvalidOperationException at Spotfire.Dxp.Framework: Attempt to perform an operation on an incorrect thread. Use ApplicationThread.Invoke() to invoke into the application thread. (HRESULT: 80131509) Stack Trace: at Spotfire.Dxp.Framework.ApplicationModel.ApplicationThread.ThrowNotOnApplicationThread() at Spotfire.Dxp.Framework.ApplicationModel.DedicatedThreadAccessible.ValidateOnApplicationThread() at Spotfire_KD4DM.DataSource.ConnectCore(IServiceProvider serviceProvider, DataSourcePromptMode promptMode) in C:......DataSource.cs:line 139 at Spotfire.Dxp.Data.DataSource.ConnectWithoutPrompting(IServiceProvider serviceProvider, DataSourcePromptMode promptMode, Boolean updateInternalState, DataLoadSettings loadSettings) the error is raise at this line, in the connectCore method protected override Spotfire.Dxp.Data.DataSourceConnection ConnectCore(IServiceProvider serviceProvider, DataSourcePromptMode promptMode) { // Retrieve the prompt service. PromptService promptService = this.GetService(serviceProvider); ... looking at the examples in the SDK or docmentation does not provide any help as it's exactly the same code everywhere.. Edit: since 10.10 there is a new property for CustomDataSources:AlwaysLoadOnApplicationThread. the default value is false but is causing issues in my case so I added this code to set it to true /// Gets a value indicating whether this data source always should be loaded on the application thread. /// protected override bool AlwaysLoadOnApplicationThread { get { return true; } } Link to comment Share on other sites More sharing options...
Tejas Devadkar Posted May 28, 2021 Share Posted May 28, 2021 Since its seems to perform some operation that needs to be performed on the applicaiton thered. Could you set theAlwaysLoadOnApplicationThread to true in your code. It should work. https://docs.tibco.com/pub/doc_remote/sfire_dev/area/doc/api/TIB_sfire-analyst_api/html/P_Spotfire_Dxp_Application_Extension_CustomDataSource_AlwaysLoadOnApplicationThread.htm Link to comment Share on other sites More sharing options...
