With the 5.0.0 version, when I receive a JSON response, I can show it in the XML tab. It's important for me because one json propertie of the message include an HTML content. So I can copy and past this content easily in a text editor. With the 5.4.0 version, the json response in displayed in the json tab solely. In the XML tab there's the message "The content you are trying to view cannot be viewed as XML". Can I reproduce the 5.0.0 behavior with the 5.4.0 version ?

Sorry for the misunderstanding, I thought you were using the Pro version as this is the forum for SoapUI Pro. Have you asked this question in the SoapUI OS forum?(I have edited the reply because the link was wrong the first time, now it is correct, sorry for the confusion)
