In the GMF search component, when there are no results found after a query, an item "No result found" is added. When clearing the query to an empty text, then clickout the search tool and then go back in, the message is still there.
This patch fixes this issue by listening the the typeahead
change
event and do an extra check there in case the query string is empty.
