Xsl-fo show PDF when no results are returned
I am using the below XSL to generate a PDF from XML
The PDF gets generated fine when there is data inside
However, there are times when this element is empty (as in the example). In this case user gets an error when trying to open the PDF (as if a corrupted PDF is generated).
I would like to have the user still open the PDF, and may be show a message in the table saying 'No results found'.
Can someone please help me in achieving this?
Thank you
