Hi all, In our business, we hope can embedding ZK portlet in other ZK portlet. I have try to do this as www.liferay.com//zh//community//forums//-//messageboards//message//6472424 It works good as those two portlet in two war file, but can't work when they in same war. I use an RuntimePortletEmbedUtil(thanks Bert Willems) class to render the embeded portlet and return the html fragment. When the two portlet in difference war file ,display as HTML, but if two portlet in same war file,display as TXT, as if the script tag and other important code lost. Debug with the code lead to org.zkoss.zk.ui.sys.HtmlPageRenders, many configuratin,I lost. Here is my work Environment: ZK6.5.2,Liferay6.1.1, liferay-plugins-sdk-6.1.1, JDK1.6.026. Render method in RuntimePortletEmbedUtil: public static String renderPortlet(final HttpServletRequest request, final HttpServletResponse response, final String portletId, final String queryString) throws SystemException, IOException, ServletException, ValidatorException { // Get servlet request / response

    HttpServletRequest servletRequest = request;
    HttpServletResponse servletResponse = 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 {
        PortletBag implPortletBag = PortletBagPool.get(PortletKeys.JOURNAL);
        com.liferay.portal.model.Portlet portlet = PortletLocalServiceUtil
                .getPortletById(PortalUtil.getCompanyId(request), portletId);
        servletRequest.setAttribute(WebKeys.RENDER_PORTLET_RESOURCE,
                Boolean.TRUE);
        result = PortalUtil.renderPortlet(
                implPortletBag.getServletContext(), servletRequest,
                servletResponse, portlet, queryString, false);

// Here I got the Wrong result }catch(Exception e) { e.printStackTrace(); }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; }

The right result should include: //zkmx([0,"xZCP",{dt:"z5ej",cu:"/mytask-portlet",uu:"/mytask-portlet/zkau",ru:"/html/workflowlogViewer/view.zul",style:"width:100%;",ct:true},[["zul.wnd.Window","xZCP0",{$$onSize:false,$$onMaximize:false,$$onOpen:false,$$onMinimize:false,$$onZIndex:false,$onClose:true,$$onMove:false,hflex:"true"},[["zul.sel.Listbox","xZCP1",{$$onRender:true,$$onSelect:false,$$onDataLoading:true,$$onAnchorPos:false,$$onAcrossPage:true,$$onInnerWidth:false,$$onPageSize:true,$$onScrollPos:false,pagingPosition:"both",model:true,topPad:0,totalSize:3,offset:0,paginal:{$u:"xZCP2"}},[["zul.sel.Listhead","xZCP3",{$$onColSize:false},[["zul.sel.Listheader","xZCP4",{$onSort:true,width:"55px",style:"text-align:center;",label:"XXXX",align:"center"},[]],["zul.sel.Listheader","xZCP5",{$onSort:true,style:"text-align:center;",label:"XXXXX",align:"center"},[]]]],["zul.sel.Listitem","xZCPc",{height:"45px",loaded:true,index:0},[["zul.sel.Listcell","xZCPd",{label:"1"},[]],["zul.sel.Listcell","xZCPe",{style:"text-align:left;')",label:"XXXX"},[]]]],["zul.sel.Listitem","xZCPf",{height:"45px",loaded:true,index:1},[["zul.sel.Listcell","xZCPg",{label:"2"},[]],["zul.sel.Listcell","xZCPh",{style:"text-align:left;')",label:"XXXXXXXX"},[]]]],["zul.sel.Listitem","xZCPi",{height:"45px",loaded:true,_index:2},[["zul.sel.Listcell","xZCPj",{label:"3"},[]],["zul.sel.Listcell","xZCPk",{style:"text-align:left;')",label:"XXXXXX"},[]]]],["zul.mesh.Paging","xZCP2",{$$onPaging:false,$onPaging:true,totalSize:3,pageSize:10,detailed:true,autohide:true},[]]],"paging"]]]]]);/]]>
