I think for modelDriven you need to set the appendPrefix parameter of the
Visitor validator to false. Essentially, struts is adding an error to
fieldErrors like ("model.field","error message") rather than
("field","errormessage") and so the freemarker templates can't match up your
fieldname to any entries in the fieldErrors map.
