When the editor is loaded, it overrides the radio,checkbox,select

/res/EditorOverride.css for those who are interested. The rule was
-moz-user-input: none !important for input and select elements.
But I bet your problem will come back as soon as you set
disabled="true" on your form elements.
You are correct. I found the CSS entry in /res/forms.css that seems
to be related.
input[disabled],
textarea[disabled],
option[disabled],
optgroup[disabled],
select[disabled] {
-moz-user-input: disabled;
-moz-user-focus: ignore;
color: GrayText;
background-color: ThreeDFace;
cursor: inherit;
}
Before to reenable the DOM mutation events on radio,checkbox,select, I
just had to comment out the -moz-user-input: none, property. However,
this time when I comment out the -moz-user-input: disabled, the
disabled inputs still don't fire Mutation events. But I'm not so sure
that this CSS rule in forms.css is actually doing anything. When I
changed the background-color and color properties to some other color
nothing changed in the editor when I loaded a page with a <input
disabled>. No matter what colors I change these to, the input looks
the same. So is this entry in forms.css really doing anything?
There's another entry in forms.css that sets -moz-appearance on inputs,
this makes them use OS theming. I had thought that the theming glue was
supposed to detect CSS overrides on form controls but maybe I was incorrect.
The reason that events don't fire on disabled form controls is that
apparently for backwards compatibility the form control event code
checks for both the CSS style and the DOM attribute and if either is set
then events simply do not occur. As you can imagine this also causes
problems for Mozilla Composer and NVu.
