.sortable("serialize") unable to handle id with '-' in it

[Bitruder]

If run .sortable("serialize") on a list with an item that has an id with '-' in it, then that id is chopped off just before the - character.

<div id="sortlist"> <div class="sortable" id="test-id">Content</div> <div class="sortable" id="test-again">Hello</div> </div>

If you make that a sortable and then serialize it, you get two test', not test-id' and `test-again'.

(using UI 1.5b)

Sorry, I now realize that your default value for expression will look for something of the form (.+)[-=_](.+). I just passed an expression option and it works now (I juse used (.+)).

Might want to add that default value to the documentation as I wouldn't have expected - to be a default separating character.
