APEX_UTIL.DOWNLOAD_PRINT_DOCUMENT

Question

My system is Apex 4.0.1+oc4j+Apex Listener+BI publisher. I need generate user-defined report layout with custom padding-left,*padding-top* values for each printing element (it is like Edit Print Attributes page in the application builder, but more complex), so the standart Report Queries and Report Layouts is not an option. DOWNLOAD_PRINT_DOCUMENT Procedure Signature 3 working fine with the pre-defined report query and pre-defined report layout. But I get 0-Byte pdf-file when trying to print document using custom XML based report data (as a CLOB) and XSL-FO based report layout (as a CLOB). Can anyone provide working example? Here is mine:
declare
f_layout clob;
f_data clob;
begin
f_data:='
<?xml version="1.0" encoding="UTF-8"?>
<DOCUMENT>
<DATE>05/17/2011</DATE>

Answer 1

Hello,
If you use a branch you don't see the download as the branch is bringing you to another/the same page.
You probably want a before header process and make that conditional with a request. On your button you define the same request for ex PRINT. In your process, you set a condition Request = Value and type in PRINT.
That should do it for you.

Dimitri
