"inst" variable can be undefined and cause Droppable to fail

[fkrueger]

I have a nested DIV structure where each DIV is draggable and droppable. When dropping a child DIV onto a parent DIV, this line of the "drop" function of ui.droppable:

var inst = $.data(this, 'droppable'); line 100 of ui.droppable.js

returns an undefined value for inst. This causes the remainder of the function to fail.

As a patch I just put an "if (inst)" around the remainder of the code. This works, and the drop succeeds.

I should also add that my droppables are all greedy.
