Hello!
I built this very simple application in Workbench to merge XML data and XDP into a 6 page PDF.
The process is triggered by an XML dropped on a watched folder. Then a generatePDFOutput operation merges them and a Write Document saves the PDF on the server. It is running but the Master Page images are not showing on the final PDF.
If I create a PDF from LC Designer the Master Page is rendered normally on the resulting PDF.
I've got no clue as to why it is happening.
Thanks very much for any ideas!
