Hi,

I have the same problem with an @Email annotated field.
The problem is that the field can allow null values (so no @NotNull, the field is nullable in the DB). It throws the same error as this thread describes. I looked into the EmailValidator and for a null/empty string it shoul be a valid email. And still I get the InvalidStateException...

	public boolean isValid(Object value) {
  | 		if ( value == null ) return true;
  | 		if ( !( value instanceof String ) ) return false;
  | 		String string = (String) value;
  |       if ( string.length() == 0 ) return true;
  |       Matcher m = pattern.matcher( string );
  | 		return m.matches();
  | 	}

I also have the same problem with a field marked with @Pattern. If the field is empty (and also is not required), when the page is saved I get to the debug page with a stacktrace and again the cause is InvalidStateException

I looked into the Pattern isValid method from SVN and it doesn't check if the field is of length 0 ( aka '' - empty string).
