I've recently noticed that the autocompleter runs the getValues method
twice for every search string. Therefore you can improve performance by

Try to change your method signature to this:

and then, on your url, you can call it like this:

I hope this helps you.

t: is absolutely critical only for two things: id, and type.
t:id or t:type clearly identify a particular tag as a reference to a
component, either an explicit one (t:id) or implicit (t:type).
Without one of those two things (or both), having, eg, t:page=Index
is meaningless.

It was being done via createQuery and uniqueResult, with the same results.

Be paranoid. Set hibernate.show_sql=true. Grab the SQL statement, and
execute it manually.
Also, can you change Listing to be non-abstract - even if you never use it?

Ah, here's the issue; when you bind a class, not an interface, as a
service, it automatically uses singleton scope.
