KeyNotFoundException is thrown when the Style.CopyFrom method is used with the built-in Normal style as a parameter

created 9 years ago

Hello,
I have an expetion "An unhandled exception of type 'System.Collections.Generic.KeyNotFoundException' occurred in DevExpress.Spreadsheet.v15.1.Core.dll. Additional information: The given key was not present in the dictionary" . This ex occurs when i change default style, change style of any cell and save document into xlsx format.
Sample:

Workbook book = new Workbook();
            book.Styles.DefaultStyle.Font.Name = "Arial";
            book.Styles.DefaultStyle.Font.Size = 10.0;
            Style st = book.Styles.Add("test");
            st.CopyFrom(BuiltInStyleId.Normal);
            st.Fill.BackgroundColor = Color.Aqua;
            book.Worksheets[0].Cells[0, 0].Style = st;
            book.SaveDocument(@"d:\xlsx_test.xlsx", DocumentFormat.OpenXml);

Thank you
