Failed to execute 'define' on 'CustomElementRegistry': this name has already been used with this registry #71

Hi Guys, I am hoping to use this loader with my project and very impressed with the this loaded so far. Great work! I am however, getting error when I am trying to include another element in the project in a different directory imported in main element( root element )..

Meaning ; when I have

< main-element > < link rel="import" href="./subDir/another-element.html" > < another-element >< /another-element > < /main-element >

I get following error. Can you guys please let me know, if this is possible? OR how do i configure the loader for it to work?

Uncaught DOMException: Failed to execute 'define' on 'CustomElementRegistry': this name has already been used with this registry at CustomElementRegistry.value (http://localhost:9000/bower_components/webcomponentsjs/custom-elements-es5-adapter.js:4:902) at Object.

Hi @hitesh97, can you work this up in a sample repo?

Hi @bryandcoulter , I found the issue with this, I had copy of same custom element defined with duplicate name in its class as 'string' hence the error.. Fixed the issue.. thanks for the support though.

Also, we are evaluating polymer 3 preview with typescript and webpack..
