XAF Blazor "Cannot override storage" error after updating to 21.2.3

created 3 years ago

Hello,
I am getting "Cannot override storage." when showing a new page after updated to 21.2.3. Attached sample solution worked in 21.1.6 but gets the error after the update. Click "Print Report" button to recreate.

Follow after breakpoint at line 35 in DXApplication10.Blazor.Server.Controllers.ReportController to see where the exception raised

Please advice.

Thank you.

    Hello,

    Thank you for your patience. The ShowReport.razor page and a custom IWebDocumentViewerReportResolver implementation are used in the attached sample. They do not initialize the XAF context while XafReportConcurrentCacheService relies on it. This causes the described behavior. It is possible to call the GetApplication method of the IXafApplicationProvider service to ensure the required initialization. You can do this on the ShowReport.razor page in the following way:

    Razor
    ...
@inject DevExpress.ExpressApp.Blazor.Services.IXafApplicationProvider applicationProvider;
...
@code {
    protected override void OnInitialized() {
        applicationProvider.GetApplication();
        ...
    }
}

    Please check this and let me know if further assistance is required. I am looking forward to hearing from you.

    Thanks,
    Ilya P
