I had a working drag drop system. I've obviously changed something along the way because I've broken it. The error I'm getting is:
inst is null line: 1751
the line itself is (inst.options.greedy)
It seems to be having some trouble with the event propagation. I tried setting greedy: false on the droppable but I just get a different error somewhere else in the code. I have site up you can view this problem with at:
(notice that it's not keeping the correct nesting of elements)
This is happening in Firefox/Safari. I had this working just a few days ago, went back to have a look at the page and noticed it was broken. I'm not sure what I changed.
The page validates to HTML 4.01 Strict and does not get any JavaScript errors in the console.
