I setup a project with a REST resource 'LBG -> Mgmt' which does a PUT with a JSON message.
The request on the 'Projects' tab works fine but when I switch to the 'SoapUI NG (PRO)' tab and I add a REST Request under a Test Case, I don't see a way to add the JSON message.
Sorry if I'm missing something obvious.
