How to implement a help feature in an iView Tray?

Answer 1

Hi Gregor,
Could the answer be connected to the class com.sapportals.portal.prt.component.SystemModes ?
I can't really see how this class is called, but it gives the error message you are talking about
The method doHelp for SP2 Patch3 is provided below
public void doHelp(IPortalComponentRequest aRequest, IPortalComponentResponse aResponse)
        IPortalComponentContext context = aRequest.getComponentContext(IPOMConstants.DEFAULT_MODE);
        IPortalComponentProfile profile = context.getProfile();
        String helpName = profile.getProperty("com.sap.portal.iview.HelpName");
        if(helpName == null)
            helpName = profile.getProperty("HelpName");
        String helpURL = profile.getProperty("com.sap.portal.iview.HelpURL");
        String isolationMode = profile.getProperty("com.sap.portal.reserved.iview.IsolationMode");
        if(context != null)
            if(helpName != null)
                String componentName = context.getComponentName();
                Locale locale = aRequest.getLocale();
                String language = locale.getLanguage();
                String helpPath = "help/" + language + "/" + helpName;
                IResource resource = aRequest.getResource(componentName, "page", helpPath);
                if(resource.isAvailable())
                    aResponse.addResource(resource);
                else
                    aResponse.write("<b>Sorry, no help available.</b>");
            } else
            if(helpURL != null && helpURL.length() > 0)
                if(helpURL.startsWith("http://"))
                    if(isolationMode != null && isolationMode.equals("URL"))
                        HtmlIFrame frame = new HtmlIFrame();
                        frame.setStyle("width:100%; height: 100%;");
                        frame.setSrc(helpURL);
                        aResponse.write(frame.toString());
                } else
                    String componentName = null;
                    if(helpURL.charAt(0) != '/')
                        componentName = context.getComponentName();
                    } else
                        int componentNameIndexEnd = helpURL.indexOf('/', 1);
                        componentName = helpURL.substring(1, componentNameIndexEnd);
                        helpURL = helpURL.substring(componentNameIndexEnd);
                    IResource resource = aRequest.getResource(componentName, "page", helpURL);
                    if(resource.isAvailable())
                        aResponse.addResource(resource);
                    else
                        aResponse.write("<b>Sorry, no help available.</b>");
            } else
                aResponse.write("<b>Sorry, no help available.</b>");
The doOnNodeReady method is also rather interesting. Perhaps another way to solve it?
protected void doOnNodeReady(IPortalComponentRequest request, IEvent event)
        NodeMode nodeMode = request.getNode().getNodeMode();
        if(nodeMode == NodeMode.HELP_MODE)
            IPortalComponentContext context = request.getComponentContext(IPOMConstants.DEFAULT_MODE);
            IPortalComponentProfile profile = context.getProfile();
            String helpName = profile.getProperty("com.sap.portal.iview.HelpName");
            if(helpName == null)
                helpName = profile.getProperty("HelpName");
            String helpURL = profile.getProperty("com.sap.portal.iview.HelpURL");
            String isolationMode = profile.getProperty("com.sap.portal.reserved.iview.IsolationMode");
            if(context != null && helpName == null && helpURL != null && helpURL.length() > 0 && (isolationMode != null && !isolationMode.equals("URL") || isolationMode == null) && helpURL.startsWith("http://"))
                request.redirect(helpURL);
