Under the hood, tapestry is using the Ajax.Autocompleter from Scriptaculous (at
least for now). One of the parameters to the javascript is "parameters" (see:
http://script.aculo.us/docs/Ajax.Autocompleter.html). Tapestry doesn't allow
you set this by default, BUT, you could extend the autocomplete mixin and
override the "configure" method (the superclass implementation is empty) to add
the value to the configuration.
Then in your custom "configure" method, you could add whatever you wanted. For
instance, you could do something like pass the current generic attribute, or
generic attribute name, or whatever you need, as a parameter. Then in your
"onProvideCompletions" method, you can grab the parameter from an injected
Request object.
