Form serialization bug if file upload is required

[e1senh0rn]

There is an issue with file upload testing.

I have few fields loaded via ajax. When I use browser - everything works just fine. Using envjs there is a strange bug with upload happens.

When I upload plaintext file HTTP-headers are added to it (view uploaded file in tmp/upload.csv). When I upload image - exception raises:

To reproduce it I've create simple rails app with those issues: https://github.com/daemon/envjs-bug

Any thoughts?

JS doesn't have a good way of dealing with arbitrary binary data. Strings are UTF8 and you can't stuff binary into them in general, so this is limitation of using JS to implement uploads.

I remember dealing with this for some case, base64 encoding the binary, but I don't remember the scope of what I was addressing. It maybe that for the purposes of the test, I had to encode on the client side. You could look in the capy-envjs for base64 ...
