Re-adding droppable() to generated content fails in IE

[vigo]

Steps to reproduce:

1) dynamically generate two arbitrary elements (e.g. via html()) 2) make the first element draggable, the latter droppable 3) re-create the two elements 4) repeat step 2 5) dragging the first element fails in MSIE6/7/8

Workaround: call droppable("destroy") between steps 2 and 3

(This might be a documentation issue)

Duplicate of ticket #5374, with a minimal (AJAX-less) testcase.

IMHO this is NOT a documentation issue: JQuery UI should detect replaced droppables are no longer part of the DOM tree and discard them (or at least do not produce an exception). Otherwise D&D becomes unusable for complex settings where many parts of a screen can be replaced/update via AJAX. This is exactly the use case I'm describing on ticket 5374. That is calling destroy on on draggables/droppables is not a valid solution for all cases.

This was already fixed, it was a problem with the auto-destroy of widgets.
