Using arrows may leave inconsistent value in the input field

[marcelosramos]

Hi again,

I have this other issue when navigating with the arrow keys: given I enter the input for the first time and I go down with the arrow down key, when I go back all the way up with the up key (until currentIndex gets to -1), then the value of the input do not clear out, it keeps the first item's value. So I see a value in the input field, but the selectedObject does not reflect that, I can't even catch it from the input-change function.

If I've typed in anything or selected any item before (even if I delete it all and set the input field to empty again), then the behaviour is what I expect, when I get all the way up, the input value goes back to what was there before.

This issue happens because of this code in line 397: inputField.val(scope.searchStr);. If I didn't type anything then scope.searchStr is undefined, and input.val(undifined) just doesn't do anything.

So, if scope.searchStr is previously initialised with null or '', or the line is replaced with inputField.val(scope.searchStr || '');, then the problem is solved.

This only happens when minlength="0"
