Currently the method render always returns a html string that can be a string that represents the correct result or a rendered error message. This change adds a mechanism that allows to fetch the HTML output. In a followup commit the rendering function is changed to return a boolean value rather than the rendering result. This will simplify the error handling and caching. Change-Id: I80760493e391911c41eb69d75a93c6a34db8852e
