DxReportViewer - Internal Server Error occurs when interactive sorting is used

created 7 months ago

Hi,
There seems to be a bug with the sort functionality whereby if the user clicks on the sort control while the report is still loading, it crashes with the below error in the console.

Code
fail: DevExpress.Blazor.Reporting.DxReportViewer[0]
System.InvalidOperationException: Document is creating.
   at DevExpress.XtraReports.UI.XtraReport.DevExpress.XtraReports.IReport.CreateDocumentCoreAsync(Single progressRange, CancellationToken token)
   at DevExpress.XtraReports.Native.DocumentCreator.CreateAsync(Single progressRange, CancellationToken token)
   at DevExpress.Blazor.Reporting.Viewer.Internal.Services.ReportBuilderWasm.BuildAsync(IReport report, CancellationToken token)
   at DevExpress.Blazor.Reporting.DxReportViewer.StartBuildAsync()
   at DevExpress.Blazor.Reporting.DxReportViewer.StartPartialBuildAsync(Int32 pageIndex)
   at DevExpress.Blazor.Reporting.DxReportViewer.HandleBrickClickAsync(MouseEventArgs args, BrickMapNodeWeb brick, Int32 pageIndex)

I have attached a simple example report, simply click on the header groupings during the first few seconds of loading to trigger a sort, or within a few seconds of a previous sort. Because of the size of the report, it is quite natural that the user may click on the headers to sort them, however they can get the crash due to the time it takes between each regeneration before it is safe to click again.

This problem is similar to https://supportcenter.devexpress.com/ticket/details/t1226866 which had the same problems when using the drill down instead of the sort.

Thanks
