I don't know if this helps, but I wrote a PersonSugggestOracle that
extends SuggestOracle
The method below calls the server. It doesn't call the server if
there are not at least 2 characters typed.
On the server side, I have a sql query that uses the characters to
perform a 'like' comparison on the first name, or the lastname so it
works similar to like a multiword suggest oracle.
On the server, I return the Person Name as a small HTML string with
<b></b> tags surround the characters that the user typed to emphasize
the part of the first or last name that is matching. I also limit the
response to 12 matching records on the server.
@Override
public void requestSuggestions(Request request, Callback callback)
{
nameCallback = callback;
String q = request.getQuery();
if (q >=2) {
asyncRequest.personSuggest(q,submitterId,12,new
PersonsReceived
(request));
}
}
Mike.
