How do I get error messages from Validators.

Ive used to the field interface to pull the validators using getValidators();

But have no idea how to return the messages from the field in error.

Example:

Code:
EditorDelegate<Field> d = new EditorDelegate<Field>() {
            @Override
            public String getPath() {
                return null;  //To change body of implemented methods use File | Settings | File Templates.
            }

            @Override
            public void recordError(String s, Object o, Object o2) {
                GWT.log("Record error: " + s);
            }

            @Override
            public void setDirty(boolean b) {

            }

            @Override
            public HandlerRegistration subscribe() {
                return null;  //To change body of implemented methods use File | Settings | File Templates.
            }
        };

            f.setDelegate(d);
