declarativewidgets not working
I can't get declarative widgets to work. The module is loaded but when I try to import a widget nothing happens and I get warnings in the console.
import declarativewidgets as dw
dw.init()

Any help would be greatly appreciated! Please let me know if you need additional info.
Same problem on Python 2.7 on Centos7 docker.
I think this is a problem with notebook 4.3.x. The docs indicate that only versions <= 4.2.x are supported.
@benchmars the console 404 error on /static/does/not/exist.js is normal. The fact that it cannot load /urth_components/urth-core-behaviors/jupyter-notebook-env.html points to an installation error. It could very much be something that broke on notebook 4.3.x.
This seems to be caused by jupyter notebook security upgrade at 4.3.1, described here: https://blog.jupyter.org/2016/12/21/jupyter-notebook-4-3-1/
I think iron-ajax element in the urth-core-import.html should also include a header X-XSRFToken.
var xsrf_token = document.cookie.match("\\b" + name + "=([^;]*)\\b");
var header = xsrf_token ? {'X-XSRFToken': xsrf_token[1]} : {};
Refer to this link to see how to add a header to iron-ajax.
