Autocomplete in .php framework doesn't seem to work any longer

I have a basic Autocomplete and Add to the database function and , for some reason, it has stopped working completely and I don't get any useful information from Firebug or otherwise what could be the problem.

I am guessing it is something simple, but don't know where to look.

This is the library where I am making the call:

What browser are you debugging on? Firefox displays Ajax errors correctly, but no others do unless you apply this patch (which will be in the next release of QCubed): http://trac.qcu.be/projects/qcubed/ticket/432

Someone found the right answer in terms of remvoing a QEvent.
