jQuery Forum

Hi,
I'm trying to set up two sets of sortable tabs where the tabs can be dragged and dropped between the sets. The tab <li> is draggable, the tab container <ul> is droppable and sortable.
I have it so that it works for each tab when dragging to the other set, and the tab is still sortable, but when I try and drag back, the drop area won't accept the tab. The methods within the drop callback within droppable still progress though.

I have set up a jsfiddle using jquery 1.9 and UI 1.9.2:  http://jsfiddle.net/paulbarrett/ET4xq/19/
Try dragging any tab over to the other tab set, then back again.

What am I doing wrong? Any help welcome.
