Polymer designer on localhost - code lost

[Keith Garrod]

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.

Exception caught during observer callback: TypeError: undefined is not a function at Polymer.ensureMeta (http://localhost:3000/components/x-meta/x-meta.html/x-meta.js:143:47) at Polymer.loadElementImports (http://localhost:3000/elements/design-host/design-host.html/[1766].js:119:22) at Polymer.loadHtml (http://localhost:3000/elements/design-host/design-host.html/[1766].js:93:12) at Polymer.loadHtml (http://localhost:3000/elements/design-canvas/design-canvas.html/[1157].js:512:21) at Polymer.loadHtml (http://localhost:3000/elements/design-frame/design-frame.html/[1561].js:50:19) at Polymer.loadHtml (http://localhost:3000/elements/designer-element/designer-element.html/[1645].js:312:19) at Polymer.codeToDesign (http://localhost:3000/elements/designer-element/designer-element.html/[1645].js:210:10) at Polymer.selectedChanged (http://localhost:3000/elements/designer-element/designer-element.html/[1645].js:155:12) at g.invokeMethod (http://localhost:3000/components/polymer/polymer.js:12:13312) at g.notifyPropertyChanges (http://localhost:3000/components/polymer/polymer.js:12:11598)

Thanks Rob. Sorry I missed that one. I tried the solutions in the attached thread and couldn't get anything to work, so I guess that means the designer is off the menu for now.
