I have installed the designer (tried 0.3.4 & master) on my localhost. When I click the <> button to go to source mode and click again to go back to wysiwig, I get the following messages in the console and the contents of my element (if any) are lost. It even happens with an empty canvas.
I have been playing around with metadata, and thought I may have caused the error, so I checked out a fresh copy from github - same result.
