Recent update for jsfsupport makes all the portlet projects failed to open the designer! The JSP file looks like the
following. It was working under NB6 release. Looks like it does not accept the portlet spec and cause 'Unrecognized
taglib uri - http://java.sun.com/jsf/portlet/components'!

<jsp:root version="2.1" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"
xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:webuijsf="http://www.sun.com/webui/webuijsf"
xmlns:p="http://java.sun.com/jsf/portlet/components">
    <jsp:directive.page contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"/>
    <f:view>
        <p:portletPage>
            <div style="-rave-layout: grid; position: relative; height: 400px; width: 400px;">
                <webuijsf:themeLinks binding="#{PortletPage1.themeLinks1}" id="themeLinks1"/>
                <webuijsf:form binding="#{PortletPage1.form1}" id="form1">
                </webuijsf:form>
            </div>
        </p:portletPage>
    </f:view>
</jsp:root>

From Winston's comment, insync needs to ignore the portlet checking:

it, it simply throws the exception.

The exception I got:
