I have a subreport which works fine on its own and works fine if it is included in the report footer of the main report. It also works fine in either a bound or unbound group footer when viewing in the HTML Preview. However, when I place it in either the bound or unbound group footer and click on Preview, it just hangs on 'Generating Report'. I also tried using the report in my ASP.net to generate a PDF and it never returns.
