Having duplicate Behaviour.register calls (on same element and event) makes neither get called

[elijahlofgren]

For me, using both:

Behaviour.register({
	'input#Form_EditForm_Title': {
		onchange: function() {
alert('something');
	}
});

and:

Behaviour.register({
	'input#Form_EditForm_Title': {
		onchange: function() {
alert('something else');
	}
});

results in neither being called. Not idea I think.

If my experiments are correct, having one universal 'a' rule overwrites any other more specific 'a.example' rules I might have later. "

Migrating our code to jQuery will help with this. See http://open.silverstripe.com/wiki/development/javascriptplatform

Raising priority since it's part of the js rewrite.

Rather than tidy up Behaviour, we'll remove it and use jQuery.
