Bug on Form.Observer

I was trying something in Prototype (i''m brand new to it) and mucked
up this:
document.observe(''dom:loaded'', function() {
	new Form.Observer(''frmLogin'', 0.3, function() {
		if($F(''txtEmail'') != '''' &&
$F(''txtPassword'') != '''') {
			$(''submLogin'').enable();
		} else {
			$(''submLogin'').disable();
		}
	});
});

now when trying it out live: i got following error in Firebug:
[Exception... "''Geen toestemming om eigenschap
XULElement.selectedIndex te wijzigen'' when calling method:
[nsIAutoCompletePopup::selectedIndex]" nsresult: "0x8057001e
(NS_ERROR_XPC_JS_THREW_STRING)" location: "JS frame ::
http://localhost/libs/js/prototype.js :: anonymous :: line 3517" data:
no]

It''s dutch but translates as Exception... "No permission to edit
property XULElement...... when calling method: "

Form.EventObserver works great, but it''s a login field, so I''d
want to
be able to press enter from the password field, instead of first
blurring the password field...

Re: Bug on Form.Observer

Okay, I found out (thank you google) that the bug had something to do
with Firefox''s Autocomplete function. By adding
autocomplete="off" in
the <input> field the bug is fixed. However, the input field is still
blurred approx every 0.3 seconds (the interval I set I''m guessing) and
indeed, when I remove the code from the Form.Observer code, it doesn''t
blur anymore.

I''m guessing it''s got something to do with how I''m
checking against
empty fields???

Any help would be great, thanks.

Re: Bug on Form.Observer

Issue is solved. The script disabled the button (wether it was
allready disabled or not), but this also causes to blur any field you
were in/on...
Issue solved with:
document.observe(''dom:loaded'', function() {
	new Form.Observer($(''frmLogin''), 0.3, function() {
		if($F(''txtEmail'') != '''' &&
$F(''txtPassword'') != '''') {
			$(''submLogin'').enable();
		} else
if(!$(''submLogin'').hasAttribute(''disabled''))
{
			$(''submLogin'').disable();
			if($F(''txtEmail'') == '''') {
				$(''txtEmail'').focus();
			} else {
				$(''txtPassword'').focus();
			}
		}
	});
});

The last if makes sure the empty field is focussed again, else you
could go back in browser history when holding backspace for example.
Also, autocomplete="off" could be removed now.
