JQuery UI Autocomplete multiple values

I'm having a problem with the AutoComplete with multiple values.

I can even re-create it on the jQuery demo site - here What开发者_如何学Go happens is if you search for something, then delete your search and enter the same search nothing happens. I have tried to turn off caching (setting to 1 like the documentation states, or even 0) assuming that it is related yet had no luck.

To recreate it:

Try A on the demo site (Multiple values), select ActionScript, now select all the text , then type 'a' again, and AutoComplete isn't triggered.

Maybe im being picky but if anyone's used AutoComplete and managed to fix this issue it'd be great

Thanks Ben

Edit:

I apologise, explained it wrong, only actually happens if you type in the same letter after you've selected the text, guess it isn't too much of a problem im just being nitpicky

I found sth. here: http://www.pengoworks.com/workshop/jquery/autocomplete.htm

Your selected text is alerted though. After closing it you can select all cities starting with 'a'.
