Hi,

I am introducing Odoo in our organization and encounter an error in my browser (Firefox and Safari).
After finding the problem location, I have a solution, but I am not certain what the best way forward is. First, is patching the code enough or is this a symptom of another problem? Second, what is the best way to submit the patch? As you might guess, I am new to tinkering with Odoo. Please advise.

Here are the details. Request:

Popup:

Odoo Client Error
TypeError: undefined is not an object (evaluating 'val.constructor')
http://192.168.99.100/web/static/src/js/pyeval.js:814

After clicking OK (:-)) the next pop-up says:

Odoo Client Error
TypeError: undefined is not an object (evaluating 'dict['widget'].get('value')[1]')
undefined:74

 I use Odoo version 8.0-20150401 from the Docker image. The code at odoo-8.0/addons/web/static/src/js/pyeval.js 814 is:

var wrap_context = function (context) {
        for (var k in context) {
            if (!context.hasOwnProperty(k)) { continue; }
            var val = context[k];
            if (val === null) { continue; }  // <======= also test against undefined?
            if (val.constructor === Array) { // <======= line 814
                context[k] = wrapping_list.fromJSON(val);
            } else if (val.constructor === Object
                       && !py.PY_isInstance(val, py.object)) {
                context[k] = wrapping_dict.fromJSON(val);
            }
        }
        return context;
};

At first glance I would say that the test for null should also include a test for undefined. Any thoughts from more experienced hackers?
