[richfaces-issues] [JBoss JIRA] (RF-10227) autocomplete: implement "nothingLabel"

[Brian Leathem (JIRA)]

    [ https://issues.jboss.org/browse/RF-10227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12813555#comment-12813555 ] 

Brian Leathem commented on RF-10227:
------------------------------------

To me, the nothing label is useful when you type something that yields no matches, and you are unsure if there are indeed no matches, or if the component  failed.

Take for example the autocomplete component in the showcase:
http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=autocomplete&skin=blueSky

In the first input, type "zz".  There is no change in the autocomplete component.  Is this because there is not value that starts with "zz"?  It's unclear.  As an application programmer I might want to give feedback to my user indicating that no match was found.

If not a _nothingLabel_ attribute, we could also meet this use case by firing an event when a search yields a zero result value.  An event-based approach might be more generally useful.
