Uncaught TypeError: Cannot read property 'vm' of undefined (index):22 onkeyup

[eskhool]

Getting this error from git master in the TODO MVC example. Is something obviously wrong since the online demo works fine.

[skariel]

I can't reproduce this, seems to work OK with my setup (both static generated HTML and served through a websocket). So, what do you see when you load the page, how and when do you get the error, are you able to create new todo items, delete them?

[eskhool]

The page loads fine but I am unable to create new to items and hence delete them , I see the following errors in the JS console (Chrome, Safari, Firefox latest on a Mac 10.9)

GET http://localhost:8080/learn.json 404 (Not Found) base.js
Uncaught ReferenceError: None is not defined VM800
Uncaught TypeError: Cannot read property 'vm' of undefined (index)

In Firefox I get a this.app is undefined....

[eskhool]

It seems that this.app is undefined in all browsers

[skariel]

can you attach here the generated (static) HTML, I would like to compare with what I get wwith my setup

Thanks!

[eskhool]

Have attached the file as static.zip.png ...just remove the png (since github doesn't allow attaching anything but images)

[skariel]

Hi, you attached the 'static' folder, but the generated HTML is just a file named todomvc.html placed in the examples/todomvc folder, just next to the 'static' folder which you attached

So currently I can't run your generated html app

[eskhool]

Sorry I didn't read your request carefully...I've attached the file again as a png

[skariel]

File seems corrupted or empty, this time I cannot open it :(

Did you use a "clean" Webalchemy install? what version of Pythonium do you have?

[eskhool]

Attached the file again...please rename to todomvc.html from the png since you can only attach images to comments on github

I used a clean webalchemy installed using:
pip -e git+https://github.com/skariel/webalchemy#egg=webalchemy
pythonium is version 0.6.2

[skariel]

Still can't d/l... anyway just send me the html file without compression, by mail to [email protected]

Also - did you get the file by running free_app.py?

[eskhool]

I ran server.generate_static()...emailed the file to you

[skariel]

OK, your html contains a few "None" that should have been tranlated by Pythonium to "undefined" or "false", see attached diff with working app. These are just a few instances, I wonder how can this happen, are you using PythonJS or Pythonium? what version of Python? I've never seen this issue, could be an issue with Pythonium, maybe I can fix this, the only problem is that I can't duplicate this error...

[skariel]

closed by mistake...

[eskhool]

Well...I am on a Mac OS X Mavericks 10.9 machine ...is it possible that the platform difference is to blame?
Python is 3.4.0...It is pythonium not python-js (I was only interested in that as an option but haven't ventured that far)...Pythonium is version 0.6.2 as I reported earlier...
Have you tried with these combination of versions? Especially Python 3.4 since that may be curve balling pythonium

[skariel]

I never tried with Python 3.4, maybe this is the problem. I'll try it

[eskhool]

It is quite possibly the problem...which version of Python 3 is it tested with? I can try that too...but since 3.4 is the future its likely we have to make it work against that

[skariel]

Indeed, Python 3.4 seems to cause this problem, I just tried it. I'll try to fix Pythonium (or patch it through webalchemy) to fix this

[skariel]

related: PyCQA/pep8-naming#10

[skariel]

fixed in master! please check before I package this up.

Also I'm not closing the issue since there is one more fix due to Python 3.4, as the link above suggests

[eskhool]

It seems to work with this fix ...just diving into the webalchemy code to get a better handle on exactly how it works...are you at all concerned that Pythonium has been abandoned by the creator?

[skariel]

I'm not concerned, I'll take maintenance and development ownership. Also this functionality is mostly orthogonal to the rest of webalchemy, and not sol long ago it worked w/o any translation of Python to JS. Also PythonJS, if ported to Python3, can be plugged in easily
