I'd look into the options for the text_field_with_auto_complete helper. If it doesn't support what you need, I'd ditch it in favor of something you have more control over. My experience with helpers/plugins like this is that they only save you time if you're doing exactly what they expect you to do. If you need anything custom, you'll incur more pain trying to work around them than they're worth.

To ditch the text_field_with_auto_complete helper, look at the HTML and JS that it generates in the rendered page. Copy and paste that, then modify it to do what you need. You can still use the controller side of the autocomplete plugin.

The JS you'll want to split the string on commas will look something like this:

var tags = $('#myTextInput').value();
var splitTags = tags.split(/\w*,\w*/);

JS regexen are pretty similar to Ruby's. That regex will split on commas, eating extra whitespace.
