Help Needed in Advaced PDF Printing! (Cannot read file error)

Question

Hi All,
I have a page that displays 2 reports. I need to Print to PDF all these reports, along with their headings to PDF. I have used the Advanced Print options.
The report queries for these 2 reports are huge exceeding the 4000 character limit of APEX query region. This query has a lot of parameters in it. Hence I created 2 views for these reports (views that get updated with new values dynamically).
Now in "Report Queries" I have 2 select statements as "select * from view_1" and "select * from view_2". When both these queries fetch records, if i click on test report, it works perfectly fine.
But when ever any one of these queries, does not return records, I get an error as "Adobe Reader could not open the file because it is either not supported file type or because the file has been damaged".
How do I handle this? Is there no way to overcome this?
Thanks,
Sumana

Hi,
Thanks for the thread. I went through it and tried using the conditional if in RTF (as mentioned in the thread). But I still face problems.
My XML structure without data is:
<?xml version="1.0" encoding="UTF-8" ?>

I gave conditional display in RTF as:
<?if:not(ROWSET1_ROW)?> No Data Found For Specified Search Criteria.<?end if?>
<?if:(ROWSET1_ROW)?> Display Table Details.<?end if?>
and
<?if:not(ROWSET2_ROW)?> No Data Found For Specified Search Criteria.<?end if?>
<?if:(ROWSET2_ROW)?> Display Table Details.<?end if?>
On saving the rtf and trying to do a preview I get "Caused by: oracle.xdo.parser.v2.XPathException: Cannot convert to number." error. What am I doing wrong here?
