RichEditPrintingDocument Export to XLS or TEXT

Hi,

i have a small Problem with the Printing Library. I merge several Components into one Document. This works great until to first Page is an RichEdit Control. When the first Control is an RichEditControl then the CreateDocument creates an RichEditPrintingDocument, and when i export this one then to XLS or TEXT it throws an InvalidCastException:

Das Objekt des Typs "DevExpress.XtraRichEdit.Printing.RichEditPrintingDocument" kann nicht in Typ "DevExpress.XtraPrinting.Native.PrintingDocument" umgewandelt werden.

PDF/MHT/HTML works fine! Sorry for setting Urgent, but i have an Installation out there where i probably need at least the XLS Export!

thx
Martin

Create an Document like this:

PrintableComponentLink pcl = new PrintableComponentLink(ps);
pcl.Component = control;
pcl.CreateDocument();

if (!ps.Equals(this._MainPrintingSystem))
            {
                this._MainPrintingSystem.Pages.AddRange(pcl.PrintingSystem.Pages);
            }

this._MainPrintingSystem.ExportToXls(fileName, xlsExport); <- Throws Exception if first Component is an RichEditControl
