Upgrading to v1.14: "TypeError: dashboardsTemplate is null"

Hi William,

Here is that console output I spoke about at our meeting last week. We’re upgrading to v1.14 and are coming across this error. Nothing appears in the browser (ie, no toolbar, no navigator, no orange). It sounds like I need to register the dashboard. Sorry if I missed the announcement, but time is of the essence. Thanks,

-Chris

But one thing I just read in your recent message was Loading Polymer or the web components polyfills multiple times is definitely known to cause problems. Regarding the polyfill: I’m noticing that my panels are being replaced with #document-fragment. Is this related? Something appears to be stripping out my panels. Thoughts? Where did the html for those two panels go?

This is a normal behavior. When you define a Polymer component, you specify what the DOM should look like in a template which by itself is not user visible element. Polymer, during the runtime, parses the template HTML to figure out its data bindings and hides the template content away from the user. It, after parsing it, does hold the reference to inner templates in the memory which gets used only when a Polymer component is created via document.createElement (or HTML).

Where in the GRAPHS plugin is document.createElement used? I cannot seem to find it. Also, my plugin did not need document.createElement before - what changed?

I was trying to describe the internals of Polymer one does not need to know about. I brought it up while trying to explain why the template was empty and why you were only seeing document-fragment inside.
