Subject RE: Validator ?s
Date Thu, 18 Feb 2010 21:53:34 GMT
Hi Jeff,

I think the error condition needs to be set in the validator:

((ValidationErrorAware)widget).setValidationError(new
ValidationError("date_selection_error", true));

Hope that's what you're looking for.  There are a few constructors - this
one uses i18n.
