Question

What’s wrong in this code?

I have a bound to a class “Fornitore fornitore” property this way:

@InitBinder
    protected void initBinder(WebDataBinder binder) {       

        binder.registerCustomEditor(Fornitore.class, new PropertyEditorSupport() {          
            @Override
            public void setAsText(String fornitoreId) throws IllegalArgumentException {
                logger.info("FORNITORE:: setValue");
                setValue((Fornitore) fornitoreService.getFornitore(fornitoreId));
            }
            @Override
            public String getAsText() {
                logger.info("FORNITORE:: getValue");
                if (getValue() == null) {
                    return "";
                } else {
                    return ((Fornitore) getValue()).getRagioneSociale();
                }               
            }           
        });
    }

Ends up with:

I’m not sure I see any relation between the spring DataBinder above and the Hibernate Session error below. I see nothing obviously wrong with the data binder, but it doesn’t have anything to do with starting a hibernate session.
