ChatterNews blank file preview when in apex:iframe
I have a VF page when an iframe on a ChatterNews VF page. When there's a file, like an image, and someone hovers over it and clicks it, the "Document Preview" box comes up, but shows nothing. What might be the issue?
And before I get questions on why I didn't use <chatter:newsfeed> directly, it's because that brings back the entire feed and I wanted to limit the page height. So, I created a separate VF page that housed the <chatter:newsfeed> and just did an iframe to it.
Here's the code:

The below is what I used. The height allows a scrollbar and everything works as it's supposed to.
<apex:panelGrid columns="1" width="100%" > <apex:outputPanel layout="block" style="overflow:auto;width:500px;height:667px" > <chatter:newsfeed /> </apex:outputPanel> </apex:panelGrid>All Answers
