connectToSortable not working until an element in the sortable is moved

I have two lists. One has a bunch of draggable li's. The other is sortable and contains a single li. If I pick up the single sortable li and move it, then allow it to revert back to its spot in the list, then I can drag draggables to the list. Otherwise they are always reverted back to their position.
