Sortable.sequence returning an arrray of empty elements.

I made this as simple as I could.  I get an array of empty strings
sequence.  The alert comes up ''''. Is just me?  I
can''t get setSequence
to work either it clears my ul.  This is with 1.6.5 and 1.7.0 beta 2.
In the Firefox debugger it shows an arrary of three items returned, but
the items are three empty strings.

Re: Sortable.sequence returning an arrray of empty elements.

Try your ids as ''item_1'', ''item_2'', etc.

The sequence code uses a regexp (as defined in options.format) and  
expects an underscore.

If for some reason you don''t want to use the underscore, change the  
''format'' in options.

You can try:
{format:      /(\d+)$/}   // returns 1,2,3
Or:
{format:     /^(.*)$/}    // returns item1, item2, item3

To use the format option, your Sortable.create line would become:
  Sortable.create(''list1'', {format:     /^(.*)$/});

Re: Sortable.sequence returning an arrray of empty elements.

Thank you, the underscore did the trick.
