Validator doesn't work if form has "." in it

[prindacerk]

I was lost at the reason why the form was not showing the validation error message on submission, When I check the state of the form, it does show it as invalid but still the error message is not visible. It seems to work fine on-blur but not on submission.

After extensive experimenting, I came to realize that the cause was because the form name has a ".". For example the name I had was "vm.form" and it wasn't working for submission. When I renamed it to "myform", then it works on submission as well.

I hope you can figure out why this is and either handle it or put it in the FAQ so people won't spend as much time as me to figure this out.
