A very tough question ... can someone answer?

Question

I need to display a portlet (or remote code, I don't care) in a plumtree top nav view. I know how to get the HTML for the portlet and have that display, but it does me no good because the c# codebehind (ASP.NET) never gets processed. All I get is the HTML. This is how I am getting the HTML (code below), but I have to have full functionality of this code, which I'm not getting. Can anybody at Plumtree (or in the user community) assist with this problem?
IPTSession ptSession = (IPTSession) m_asOwner.GetUserSession();IPTState appState = ptSession.GetStates().Get(1);IPTGadget myNavPortlet = (IPTGadget)ptSession.GetGadgets().Open(597,false);object[][] myObject = myNavPortlet.GetHTMLText(appState);string myString = "";for(int i = 0; i<myObject[PT_MARKUP_ARRAY_COLS.PT_MARKUP_ARRAY_COLS_FRAGMENT].Length; i++){ if(myObject[PT_MARKUP_ARRAY_COLS.PT_MARKUP_ARRAY_COLS_FRAGMENT] != null) {  myString += myObject[PT_MARKUP_ARRAY_COLS.PT_MARKUP_ARRAY_COLS_FRAGMENT][i].ToString(); }}mySpan.AddInnerHTMLString(myString);

Jason,
I have written some navigation schemes that place portlet content into a nav area. It isn't a simple task but I will share with you how I have accomplished it.One tricky thing is that using GetGadgets() from the PTSession could negatively affect the performance of your navigation scheme if it is called on every page draw for every user. To work around the performance implications I created two pages in my portlet project. One page has any scripts that are used in the portlet, and another page is the 'dynamic' portlet content that would potentially be different for each user. The 'scripts' file can be shared for all users and in the scripts file there is a transformer tag that represents the URL to the 'dynamic' page. When the navigation scheme is being drawn it uses the included function GetPortletHTML to retrieve the portlet content from PTSession. The HTML returned from this function is cached on the application and shared for all users. When the navigation scheme is output and the page is drawn the On Page Load event triggers a javascript function that grabs the URL for the 'dynamic' page and makes a client side HTTP request for the portlet content./*** Returns a string representing the HTML of a portlet based on the ID being passed in.* * @param asOwner - The activity space currently in use* @param className - the STR_MVC_CLASS_NAME of the view loading the portlet* @param portletID - The ObjectID of the portlet you wish to load* @param useCachedVersion - Whether it should use the version cached on the session or reload the portlet* * @return String - The Portlet HTML*/publicstaticString GetPortletHTML(AActivitySpace asOwner, String className, intportletID, booleanuseCachedVersion) {  // cache the HTML on the session.. you only need to get this once.  ISessionManager settings = asOwner.GetSubSession();  IApplication application = asOwner.GetApplication();  String sReturn = null;  if(useCachedVersion) {    sReturn = (String)settings.GetAttribute("portlet" + portletID);  } if(null!= sReturn) {    returnsReturn;  } else{    Object m_asOwner = null;    HTMLTableCell myCell = newHTMLTableCell();    IPTSession oSession = (IPTSession)asOwner.GetUserSession();    IPTGadget oGadget = (IPTGadget)oSession.GetGadgets().Open(portletID, false);    Object[][] HTMLText = null; finalString STR_PAGE_ID = "PageID"; intnPageID; INavigationModelRO navModel = (INavigationModelRO)asOwner.GetModel("NavigationModel"); try{      nPageID = navModel.GetCurPageID();    } catch(Exception ex){      nPageID = 0;    } ASURL myASURL = newASURL(asOwner); myASURL.SetLinkGetCachedSpace(asOwner); myASURL.SetControl(className); myASURL.AddControlArgument(STR_PAGE_ID, nPageID); String sHostPageURI = myASURL.GetURLAsString() + LinkConstants.AMPERSAND; try {       IPTState m_objAppDataState = AppDataObject.GetAppDataObject(0, nPageID, sHostPageURI, asOwner);         String[] sHeaders = (String[]) asOwner.GetCurrentFormData().GetElement (HttpUtils.HASHTABLE_CONTROL_KEY_HTTP_HEADERS); if((null!= sHeaders) && (sHeaders.length > 0)) {        m_objAppDataState.Add(AppDataObject.PT_HEADERS_KEY, sHeaders[0], 0, true); } HTMLText = (Object[][]) oGadget.GetHTMLText(m_objAppDataState); // invoke the "UI transformer" function -jas GatewayUtils.AddMarkupToElement(asOwner, oSession, HTMLText, myCell, asOwner.GetString(617, "ptmsgs_portalbrowsingmsgs"), asOwner.GetString(618, "ptmsgs_portalbrowsingmsgs"), 0); } catch(Exception e) {      // don't throw an exception.. just return error string.. it timed out. we'll get it next time       return"<p><b>Error displaying portlet</b></p>";    } sReturn = myCell.GetInnerHTML(); settings.SetAttribute("portlet" + portletID, sReturn ); returnsReturn; }} Here is a simple example of a Scripts file from a simple portlet where the portlet ID is 4123, and the dynamic page is "/favorites/favorites.jsp" (relative to the remote server used for this portlet's web service):
scripts.jsp:<% // first construct the URL. // For this sample use hardcoded values for portletID, and linkSummaryPage // this would likely come from a configuration file for the navigation scheme int portletID = 4123; String linkSummaryPage = "/favorites/favorites.jsp";%><pt:gatewayLinkname="portletSummaryURL<%= portletID%>"id="portletSummaryURL<%=portletID%>" xmlns:pt= 'http://www.plumtree.com/xmlschemas/ptui/'pt:objectID='<%= portletID%>'pt:href="<%=linkSummaryPage%>" ></pt:gatewayLink> <!-- Div tag to set the http in that has a response. --><div id="getSummaryResponse<%=portletID%>"></div><script> document.PCC.RegisterForWindowEvent("onload", loadPortlet<%=portletID%>); function loadPortlet<%=portletID%>() {    var pageIDElement = null;    var element = document.getElementById('portletSummaryURL<%=portletID%>');    if (element) {      doGet<%=portletID%>(element.href);    } } // Fires the http get request function doGet<%=portletID%>(sPortletURL) {    var getRequest = new PTHTTPGETRequest(sPortletURL, handleGetResponse<%=portletID%>);    getRequest.invoke();   } // handler receives a PTHTTPResponse object as its single argument function handleGetResponse<%=portletID%>(response) {    var element = document.getElementById('getSummaryResponse<%=portletID%>');    element.innerHTML = response.responseText;   } // Include any other scripts that might be used in favorites.jsp here</script> favorites.jsp:
<% // Here is where you would put code to read the users preferences for favorites // From the EDK%>
Hope this helps,
