Thanks Kevin.
We have another project where I have a 'placeholder' PDF to serve up when there are no reports, as you suggested. It worked well, but this particular site is a unique case where on occasion the customer can enter an order with just some comments, and no actual line items being selected.
In these cases, my client wants the order to still be emailed with the customer details in the header and the comments in the footer so their sales team can still chase up the customer.
I am thinking that most of the other workaround are based around 'normal' Clarion reports on Win32 using the Previewer. In this case, I am generating a PDF directly in the background with no previewer at all, so not sure if those workaround will be effective??
Cheers,
Devan
