Unable to view Message in Message Log for Rest Mock Service

I have created a Mock Rest Service, when I post a request to this Mock Service from a Java application I gat a response back to my Java Rest Client and I can see in the Message Log of the Mock service in SoapUI that a message was received but I cannot see the actual request/response in SoapUI. I tried to click on the message in the message log view but nothing is displayed and I am sure this has worked for me in the past with a Soap Mock Service, does it not work for a Rest Mock Service? I tried this on SoapUI install on a Mac(SoapUI 5.2.0) and also in Windows 7(SoapUI 5.0.0)?
