New Xwiki user here and first time post. I am very impressed with the XWiki platform. We are using it for our company intranet and it has been able to handle just about everything that I've wanted and without too much pain. A bit of a learning curve, but I think I have a much better grasp of it now. That said, I have a strange issue that I've been able to confirm on two different instances of XWiki (both 5.4.4 and 5.4.3). I am using the PDF Embed Object macro to display PDF attachments inline, however the ability to view those PDFs full screen in the browser is hampered (I have users on IE 9, so the newer pdf.js based viewers won't work for me). Here's what I'm seeing: I have a test user that has edit rights on a page. They can create a page, edit it and upload an attachment to the page. They use the pdf embed object macro like so: {{pdf filename="somefile.pdf" /}} This macro uses the <object> tag to display the PDF inline, however the "VIEW THIS PDF FULL SCREEN" button is just a hyperlink like so: <a href="/xwiki/bin/download/MySpace/MyPage/somefile.pdf">View this PDF full screen</a> The PDF is displayed inline just fine with the object tag, however the button to view the pdf fullscreen doesn't seem to work properly if the user that uploaded the attachment didn't have programming rights when the file was uploaded. When that same test user views the page and clicks the "VIEW THIS PDF FULL SCREEN" button, the file is actually downloaded rather than viewed in the browser. My guess is that something in the server is setting the content-disposition differently based on the rights? If I give that user programming rights after they've uploaded the file, they still cannot view the file inline (the file is still downloaded rather than viewed inline). However, if that user now tries to upload the same file again (now that they have programming rights), then the button will properly show the full screen PDF inline. Has anyone seen this behavior or know of a workaround? Thanks for any advice or pointers!
