Autocomplete: Tab on multiple Autocomplete should not change focus after selecting

[[email protected]…]

1. Create a multiple-autocomplete (or go to ​http://jqueryui.com/demos/autocomplete/#multiple).
2. Type the beginning of a valid entry (e.g. "ja")
3. Press the down arrow to highlight the first entry
4. Press TAB

What happens: the entry is selected the autocomplete panel closes a separater is insert into the autocomplete input focus moves to the next form element or link.

What should happen: the entry is selected the autocomplete panel closes a separater is insert into the autocomplete input (focus remains in the autocomplete input, awaiting the next item)

NB: a _second_ TAB press, when the panel isn't open, _should_ change focus.

The problem lies in these lines:

passthrough - ENTER and TAB both select the current element case keyCode.TAB:

if ( !self.menu.active ) {

return;

} self.menu.select(); break;

If self.menu.active is true, the event's default behavior should be prevented, just like in the case for keyCode.ENTER.

Now that I look at the example more closely, it seems to me that the desired behavior is in the example's "select" function rather than in the library itself. Indeed, adding

event.preventDefault();

to the beginning of the example's "select" function works as expected. Thus, the question is now:

1. should the user who wants the "multiple" functionality include event.preventDefault()

or

2. is there a bug in the handling of the return value -- specifically, is returning false not properly preventing the event's default behavior.

If option 1 is the case, see ​https://github.com/jamesarosen/jquery-ui/tree/6661_fix_1 for a fix to the demo.

If option 2 is the case, see ​https://github.com/jamesarosen/jquery-ui/tree/6661_fix_2 for a fix to the autocomplete library itself.
