SPring MVC: manage BindigException
===

I have a problem with the binding of a form input text to a Integer field of the bean to which the form is binded. If I write a wrong number in the input text (eg: "12b") I have a Binding Exception. So, I set a @InitBinder in my controller in this way:

        @InitBinder
        public void initBinder(WebDataBinder binder) {
            binder.registerCustomEditor(Integer.class, new CustomIntegerBinder());
        }

Where CustomIntegerBinder is implemented as follows:

        public class CustomIntegerBinder extends PropertyEditorSupport {

	    @Override
	    public void setAsText(String text) throws IllegalArgumentException {
	        try {
	            setValue(Integer.parseInt(text));
	        } catch (Exception e) {
		    //I WANT TO ADD ERROR TO THE ERROR LIST!
	        }
	    }

	    @Override
	    public String getAsText() {
	        return getValue().toString();
	    }
        }        

My question is: how could I succeed in adding a message error to the errors list, so that a conversion error would not cause a crasch of the application, but a message to be printed in the "errors" tag in the jsp?

Thank you!
