todo_ddc doesnt run.

[andrey-zakharov]

Hi, Vittorio!

I have updated polimerize_elements in a hope of fixing some errors in console while running todo_ddc,
but with latest generated files (
I've still got:

Uncaught TypeError: Cannot read property 'addEventListener' of null

looks like input missing in paper decorator or something else.

I've took sources from this but hack it to use
https://github.com/andrey-zakharov/polymerize_elements

which contains latest generated files for polyner 2.0.0.rc6.

Could you please, point me to direction where to dig in.
Thanx.

I've tagged your PR and updated todo_ddc, updated bower_resolutions.yaml to rc6 and now it works for me.

Can you check if this works for you too ?

pub upgrade (polymer_element 0.7.0+1 (was 0.7.0)) and rebuild of everything does not fix issue.

[dam0vm3nt]

I've made another test and had to fix resolutions again but it is working, this is what I did :

1. bazel clean --expunge
2. pub get && polymerize init && bazel build default
3. cleared cache of chrome
4. http://localhost:8000

and it worked.

My test conf is :

• dart 1.22.1
• polymerize 0.7.1
• chrome 57.0.2987.133

[andrey-zakharov]

Thanks! Finally it works after all purge commands and rebuild and cache purge.
Issue could be closed, app is working well (add, remove todos), but still got
404 for
GET http://localhost:8000/bower_components/web-animations-js/web-animations-next-lite.min.js

what it could means?

[dam0vm3nt]

cool.

As for the missing web-animations-next-line.min.js I've noticed it too but I've always thought it was a polymer (js) / polymer_elements (js) issue due to their rc status. As they are near to the stable release and it is still happening I think it's time to inveastigate it deeply.

I'll open a new issue on this just to remember.
