Tempex field with select, checkbox and radiobuttons not working properly

It seems that tempex is not working properly with selectboxes, checkboxes and radiobuttons. They do work properly with text, number and tokens.

Selectboxes & Checkboxes: Tempex field is not triggered at all it seems

Radiobuttons: Tempex field thinks the value of the radiobutton is simply the first radiobutton defined in the form. (e.g. when you have radiobuttons Yes and No in your Flexform Form, tempex always thinks the value is Yes. Regardless of which radiobutton is checked.
