Error when using toArray about nestedsortable

[TheSin-]

After reading the code, I see now that the item id (or id attribute) NEEDS to be key[=-_]id, I didn't not find this in the doc at all and I was just setting it to id. so data-id="1", this causes a the error, I had to change to data-id="idontcare_1" which is ugly. To that end changing expression to some that does not return an array of 3 items would also break it. This doesn't seem like a great fix.

I'd recommend setting a default expression to /.+[=-_](.+)/ so it's only returning one item which is the id. that way other can just override the expression to return /(.*)/ for like in my case and chang the code to expect only one, so parentItem[0] instead of parentItem[2].

Anyhow I hope the helps other and I wish I didn't have to ugly up my html to make this work, but at least it's working now ;) I'll leave this open for other and incase you want to fix this in the future.

Yes kind of a pain, you need to set the li element's id to be 'text_123' instead of '123'. Tacking on this comment so people can search for the console error I received and easily find this thread:
