The second a third autocomplete input in Showcase demo http://localhost:8080/showcase/richfaces/component-sample.jsf?demo=autocomplete  doesn't work properly on the mentioned browsers/devices:
- type "Al"
- select "Alabama" -> input field is containing "Alabama"
- type ", P"
- select "Pennsylvania" with mouse/finger -> input field is containing "Pennsylvania, P" (it should contain "Alabama, Pennsylvania")
The Safari developer's console on iPhone doesn't display any error.
It works properly on:
- Opera 11.50
- Firefox 6.0
