ERRest problem updating Integer attributes

I'm building an ERRest app and I'm having a problem with my updateAction() method. It works fine for String or Boolean attributes, but not for Integer attributes. When I try to update an Integer attribute my didSkipValueForKey filter delegate method gets called. My updateAction() looks like this:

	ERXKeyFilter updateFilter = updateFilter();
	setFilterDelegate(updateFilter);
	update(maillist, updateFilter);
	editingContext().saveChanges();
	return response(maillist, showFilter());

updateFilter is set up like this (I put in the logging in an attempt at debugging):

	private ERXKeyFilter updateFilter() {
		ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
		logger.info("includes: " + filter.includes(MLMaillist.LOCAL_SENDER_POLICY));
		logger.info("matches: " + filter.matches(MLMaillist.LOCAL_SENDER_POLICY, ERXKey.Type.Attribute));
		return filter;
	}


	private void setFilterDelegate(ERXKeyFilter filter) {
		filter.setDelegate(new ERXKeyFilter.Delegate() {

			public void willTakeValueForKey(Object target, Object value, String key) throws SecurityException {
				try {
					logger.info("validating key: " + key + " value: " + value);
					((MLMaillist)target).validateValueForKey(value, key);
				} catch (ValidationException e) {
					logger.info("Throwing SecurityException");
					throw new SecurityException(e.getMessage());
				}
			}

			public void didTakeValueForKey(Object target, Object value, String key) throws SecurityException {
				logger.info("validating key: " + key + " value: " + value);
			}

			public void didSkipValueForKey(Object target, Object value, String key) throws SecurityException {
				new RuntimeException().printStackTrace();
				logger.info("validating key: " + key + " value: " + value);
			}
		});
	}

The "localSenderPolicy" attribute has an ERXKey definition:

  public static final ERXKey<Integer> LOCAL_SENDER_POLICY = new ERXKey<Integer>("localSenderPolicy");

And when I try to update it I get the following results:

  [2012-07-12 16:14:33,257] INFO  rest.MLMaillistRouteController.updateAction - method: PUT
  [2012-07-12 16:14:33,257] INFO  rest.MLMaillistRouteController.updateAction - uri: /cgi-bin/WebObjects/Maillist.woa/-60666/ra/Maillist/1239.json?sfu_token=NNQX1krpbzleYug3eDItdSqC4z49yh7vmxGIWHWw.bIHwn4Xtx2eNhr.bDGECvh5
  [2012-07-12 16:14:33,257] INFO  rest.MLMaillistRouteController.updateAction - request doc: {

  }

…

  [2012-07-12 16:14:33,379] INFO  rest.MLMaillistRouteController.didSkipValueForKey - validating key: localSenderPolicy value: [localSenderPolicy=0]

I'm using Wonder 5.7-SNAPSHOT, but I've tried a number of different versions and I get the same results.

Any help would be greatly appreciated!
