Got the following error trying to get the simple paper button example to work:

I have no idea how to progress this.

No breakpoints I set in chrome trigger, which suggests something is wrong with source mapping.

Moreover, I can't set the breakpoints to the right part in the code as can be seen (clicked every line on the left that was possible). Using the catch on exception feature, I can't inspect any of the variables listed.

I've tried this in Chrome which I understand shouldn't need the webcomponents.js lib. Tried it with and without. Version: 1.7.0.0

Any ideas?

Adding the import manually works around this issue for me (once I bower check the paper elements), but my understanding is I shouldn't have to do this.

<link rel="import" href="myapp/bower_components/paper-button/paper-button.html">

Moved over to the new https://github.com/tbroyer/gwt-maven-plugin from the older Mojo one and the problem went away. No need to investigate further.
