T4 - Autocompleter without doing a full page re-render

Hi all,

I'm using the @Autocompleter component and have noticed that at each 
interaction (lookup and selection) it essentially re-processes the whole 
wrapping page at the back end. In this case, I have a couple of 
sometimes large database lookups that are being re-queried and as a 
result the autocompleter appears slow and the server is working far 
harder than it needs to.

Is there a way of avoiding this excess processing?

Thanks, Paul.

You can distinguish between a "normal" render and an "ajax"-render via

getRequestCycle().getResponseBuilder().isDynamic(),
