Streaming PDF to iframe doesn't work with Portlet Bridge 3.x

[delphinus818]

I use the following to stream PDF (via a servlet) to IE9.  It works outside of the portlet, but not inside.  Anyone has any idea?

<h:panelGrid columns="1" style="width:960px">

            <iframe id="pdfViewer" src="../reportdocuments/report.pdf" width="1100px" height="800px" type="application/pdf"/>

                <p:separator height="5" width="100%"/>

                <p:spacer height="5"/>

</h:panelGrid>

Are there any errors in the server console or the browser?

With such little information it's a bit hard to know what might be happening.
