> When downloading an Excel workbook, org.jboss.seam.excel.ui.UIWorkbook always sends the HTTP response header "Content-Disposition: inline; filename="xxxx.xls" where xxxx is the value of e:workbook's filename attribute.
> This header causes problems on some installations of IE 6, 7, and 8 with Excel 2002. Depending on how some settings are configured in the OS, the document may never open after download.
> Changing the HTTP response header value to "Content-Disposition: attachment; filename="xxxx.xls" solves the problem. Notice the only difference is the word "attachment" vs. "inline". I would like the capability to choose between these two, just like jboss-seam-pdf.jar provides the same capability with its org.jboss.seam.pdf.ui.UIDocument:
> <pdf:document title="Some Title" disposition="attachment"> ... </pdf:document>
> Mail attachments in Seam provide the same capability:
> <m:attachment value="#{person.photo}" contentType="image/png" disposition="inline"/>
> I'm attaching a patch against Seam 2.2 trunk which provides this capability. With this patch, we can now write:
> <e:workbook type="jxl" disposition="attachment" ...> ... </e:workbook>
> or
> <e:workbook type="jxl" disposition="inline" ...> ... </e:workbook>
