Dear all,
I'm getting "Reject process action" message and I cannot process my ajax function in my nested portlet.
I tried several things according to the advises of this thread https://www.liferay.com/community/forums/-/message_boards/message/37102728 :

• add <add-default-resource>true</add-default-resource> to my liferay-portlet.xml
• portlet.add.default.resource.check.enabled=false in portal-ext.properties
• add portletId to the portlet.add.default.resource.check.whitelist property in portal-ext.properties

Other guys in the above thread also tried these advises, but problem is still there.

My Ajax code properly works with Liferay 6.1.2.

I suppose it's a bug.

My code:
I embed my portlet with this code:

	public static String renderPortlet(final PortletRequest request, final PortletResponse response,
			final String portletId, final String queryString) throws SystemException, IOException, ServletException,
			ValidatorException, PortletContainerException {
		// Get servlet request / response
		HttpServletRequest servletRequest = PortalUtil.getOriginalServletRequest(PortalUtil
				.getHttpServletRequest(request));
		HttpServletResponse servletResponse = PortalUtil.getHttpServletResponse(response);
		// Get theme display
		final ThemeDisplay themeDisplay = (ThemeDisplay) servletRequest.getAttribute(WebKeys.THEME_DISPLAY);
		// Backup current state
		PortletDisplay portletDisplay = themeDisplay.getPortletDisplay();
		PortletDisplay portletDisplayClone = new PortletDisplay();
		portletDisplay.copyTo(portletDisplayClone);
		final Map<String, Object> requestAttributeBackup = new HashMap<String, Object>();
		for (final String key : Collections.list((Enumeration<String>) servletRequest.getAttributeNames())) {
			requestAttributeBackup.put(key, servletRequest.getAttribute(key));
		}
		// Render the portlet as a runtime portlet
		String result = "";
		try {
			com.liferay.portal.model.Portlet portlet = PortletLocalServiceUtil.getPortletById(
					PortalUtil.getCompanyId(request), portletId);
			portlet.setRenderWeight(0);
			servletRequest.setAttribute(WebKeys.RENDER_PORTLET_RESOURCE, Boolean.TRUE);
			String columnId = null;
			Integer columnPos = null;
			Integer columnCount = null;
			try {
				themeDisplay.setAjax(true);
				String ajaxId = request.getParameter("ajax_id");
				if (ajaxId != null) {
					servletResponse.setHeader("Ajax-ID", ajaxId);
				}
				servletRequest = PortletContainerUtil.setupOptionalRenderParameters(
						servletRequest, null, columnId, columnPos, columnCount);
				PortletContainerUtil.render(servletRequest, servletResponse, portlet);
//				StringBundler _result = render(portlet, columnId, columnCount, columnPos, servletRequest, servletResponse);
//				result = _result.toString(true);
				
			} catch (Exception e) {
				LOGGER.error("Cannot render the embedded portlet", e);
			}
		} finally {
			// Restore the state
			portletDisplay.copyFrom(portletDisplayClone);
			portletDisplayClone.recycle();
			for (final String key : Collections.list((Enumeration<String>) servletRequest.getAttributeNames())) {
				if (!requestAttributeBackup.containsKey(key)) {
					servletRequest.removeAttribute(key);
				}
			}
			for (final Map.Entry<String, Object> entry : requestAttributeBackup.entrySet()) {
				servletRequest.setAttribute(entry.getKey(), entry.getValue());
			}
		}
		return result;
	}

my jsp:

<portlet:actionURL name="fakeOp" var="selectURL" />

<aui:script>
Liferay.provide(
	window,
	'<portlet:namespace />fakeOp',
	function() {
		var A = AUI();
			var url = '<%= selectURL.toString() %>';
			var gw = A.one('#<portlet:namespace />gws');
			A.io.request(
				url,
				{
					//data to be sent to server
					data: {
						<portlet:namespace />test: gw.val()
					},
					dataType: 'json',

					on: {
						failure: function() {
							...
						},
						success: function(event, id, obj) {
							...
						}
				}
			}
		); //END of io Request
	},
	['aui-io']
); //End of Provide

</aui:script>

<aui:form name="fm" action="<%= selectURL.toString() %>" method="post">
	<aui:fieldset>
		<div id="messageResult" style="visibility: hidden;"></div>

		<aui:select id="gws" name="gws" label="Select:" helpMessage="Select here !!!!!"
			onChange='<%= renderResponse.getNamespace() + "fakeOp();" %>'>
			....
		</aui:select>
	</aui:fieldset>
</aui:form>
