Hi,
Cannot see anything obvious from the code.
I did a small test by adding a delete link to the ExcelTableExportPage example, which I assume your
code is based on? Adding the delete link worked just fine though. At this stage you might want to
back out some of your code to just a bare bones page with a edit/delete link and make sure that
works and then fleshing it out?
regards
