Allow sending message without subject

[andrey-utkin]

When I watch received messages in mcabber, I see it like below. Even if --subject arg is not used, it still sends empty subject (see []). It would be handy to be able not to send subject field altogether.

I have the same issue. I got one property in schema "default": null and this fails.

Were you able to find a fix?

[tmburnell]

This is not a fix but i have a workaround that i posted in #152

I did some research and the big actually looked like it was in angular ... it did not check the existence of an object before running the foreach on it. So i might be remedied in future angular updates. However I never opened a ticket in angular (i would have to refind the code).

Any progress in this issue?

[GonziHere]

problem is here:

    FormGroup.prototype.patchValue = function (value, options) {
        var _this = this;
        if (options === void 0) { options = {}; }
        Object.keys(value).forEach(function (name) {
            if (_this.controls[name]) {
                _this.controls[name].patchValue(value[name], { onlySelf: true, emitEvent: options.emitEvent });
            }
        });
        this.updateValueAndValidity(options);
    };

because this function assumes that value is object, not null. There isn't any typecheck before Object.keys(value) is called.
