1.7.2 Sortables and placeholder index


I've been trying to figure this out all day! I've got a problem where
my placeholder isn't drawn on the screen. The placeholder class
doesn't seem to be added to the sortable. The placeholder is
invisible, not red and has not picked up the border height.
.here{background:red;border:solid 50px #aaa;z-index:
2000;visibility:visible;display:block}
if I add the ui-sortable class then it picks up the height change of
the border but is still invisible.
.here, .ui-sortable-placeholder{background:red;border:solid 50px
#aaa;z-index:2000;visibility:visible;display:block}
$('div.ca').sortable({
    connectWith: 'div.ca',
    items: 'div.sortable',
    zIndex:1001,
    placeHolder: 'here',
    forcePlaceholderSize: true,
    cancel: 'div.mp,li',
    applyTo: 'body'
});
Anyone got any ideas where to start looking next?
