ui - not compatible with jQuery.noConflict()

Hello,

it seems that ui is not compatible with jquery.noConflict();

I use something like this:

var $j = jQuery.noConflict();

but then ui gives me:

TypeError: $(element).bind("setData." + name, function (e, key, value) {return self.setData(key, value);}) is undefined

in firebug, when trying to use sortable.
