[displaytag-user] Export to excel etc. doesn´t work

[Torsten Frehe]

I am using displaytag with a TableDecorator wrapper in a Struts app that uses Tiles.
Know I want  to use the export-function.
But the export-function will not export the table into csv, excel,pdf or xml.
It always open the same page in the same browserwindow without data.
I also want to export the data into pdf, but the export to pdf isn´t shown in the footer.
Who can I export the data?Where is the mistake?

The displaytag.properties looks like this:
export.banner.sepchar= |
export.types=csv excel pdf xml
export.excel.class=org.displaytag.export.ExcelView
export.excel.include_header=true
export.excel.label=Export to excel
export.excel.filename=tabelle.xls
export.pdf=true
export.pdf.class=org.displaytag.export.PdfView
export.pdf.include_header=true
export.pdf.label=Export to pdf
export.pdf.enable=true
