LDN - Luminis Developer Network

We have reports produced by our Cognos system that are output as PDF's. For a number of reasons, the Cognos staff prefers to deliver these reports in this format. They would like me to create a tab that would load this report as the full frame of the tab. When I do this, I get the PDF loaded in a frame that is only about 1-2 inches high - clearly not the height of the PDF. I think that I've traced part of the problem to a script in the Luminis layout that tries to automatically determine the height of the content being loaded into the frame. My suspicion is that it is unable to determine what to do with a PDF, so loads a minimally-sized frame.

Has anyone else run into this and have any suggestions for work-arounds?

Thanks,
David
