Doesn't seem to work with multiple choice fields

[caponica]

Hi. This bundle is really useful (the name fits), but I'm having problems applying the shtumi_ajax_autocomplete type to a multiple-choice field.

Is this not supported or is there some marvellous setting that I've overlooked? Or perhaps some magic I need to work with a DataTransformer?
