Hi Please assist I am building .net core site with kentico 13. I am getting this error below
Missing page context data. If required use IPageDataContextInitializer.Initialize method to initialize the context manually. For POST actions use HtmlHelper extension method Html.Kentico().PageData() to persist the page context

This is a newbie question about the DocuSign API. I just downloaded the C# example. Excellent flow, which demonstrates the API capabilities. But I do not understand how the Get() action method is getting called in eSignature\Controllers\EgControllers. I do not see any route to the Get() action method and the default routes defined in Startup.cs point to an Index action method, not Get. Shouldn't the Get() action method be named Index()?
I assume you downloaded a C# Quickstart that include a lot of calls built using the C# SDKs.
The C# eSignature SDK is making all calls for you, including the GETs.
When you use an SDK, it's a wrapper that handles the calls for you, so you don't have to worry about GET or POST or JSON.
For example, this line in the C# code you have (eSignature/Examples/GetEnvelopeInformations) is making a GET call inside the SDK:
return envelopesApi.GetEnvelope(accountId, envelopeId);
I'm trying to implement OpenNTF Domino API as a replacement in our project but it fails with this message:
"OpenNTF Domino API: org.openntf.domino.utils.Factory is not initialized for this thread!"
Code snippet:
boolean init = Factory.isInitialized(); // false
Database db = Factory.getSession().getCurrentDatabase(); // This fails of course because no Session
I'm implementing the call in a JAVA DAO behind a EXTLib Servlet in XPages.
So it's not called by an XPage but as an REST API call.
The Domino API Demo DB is working so the server install seems to be OK.
Is there a setup, properties I'm missing to init it ?
Yes, there is specific setup require for non-XPages access, as done in OsgiWorlds on OpenNTF. Nathan has added a DAS extension specifically for REST access from Graph database. You basically need to initialise the session for the Factory before trying to access it, generally done in the Servlet when it initiates the HTTP connection. Please contact me on Twitter (Paulswithers) so the team can work with you. Also it's worth you having a look at the OsgiWorlds source code. Although that's for a Vaadin servlet and allows defining a development user to run as, in production mode it also uses the logged on user name and the configuration class and calls to it from the servlet are effectively what you need from the REST servlet.
Is there a way to expose a Java rest web service in Liferay but not in a portlet, that can receive JSON request and store the data in Journal Article?
Therefore when a user logs into Liferay they will be see web content
Yes there is : JSONWebServiceActionsManagerUtil.registerJSONWebServiceAction
For instance :
Class<?> serviceImplClass;
Method serviceMethod;
Object serviceImpl;
String path = jsonWebServiceMappingResolver.resolvePath(serviceImplClass, serviceMethod);
String method = jsonWebServiceMappingResolver.resolveHttpMethod(serviceMethod);
JSONWebServiceActionsManagerUtil.registerJSONWebServiceAction("/yourwspath", serviceImpl, serviceImplClass, serviceMethod, path, method);
You should then be able to see the new web service in http://SERVER/api/jsonws
Well yes, Liferay has a full API (even JSON-based, SOAP optional, no classic REST though) that you can use. A simple Stackoverflow answer is not the right place to give a full introduction on how to work with Liferay's API, but you might want to look up Servicebuilder (which is used to create Liferay's API) and then look at JournalArticleService and related services: The Web Content Management API is called "Journal" in Liferay (for historical reasons)
I have created an iPad storyboard application using the newest version of Monotouch. My first screen is a login screen that I only want to show if the user has not saved his credentials. If credentials are available I want to instead navigate to the UITabBarController that is the second scene. I can't seem to find any documentation on how to do this. I tried creating an instance of the UITabBarController and pushing to it but it does not work.
homeScreen = new HomeTabBarNavigator(this.Handle);
this.NavigationController.PushViewController(homeScreen,true);
HomeTabBarNavigator is a UITabBarController that is already linked to other scenes. I get the following error:
[ERROR] FATAL UNHANDLED EXCEPTION: System.NullReferenceException: Object reference not set to an instance of an object
I assume I am getting this error because I have not defined any views to the ViewControllers property of my HomeTabBarNavigator. I was hoping that those views were already defined but that does not seem to be the case. Any ideas.
The best solution I could find is to call PerformSegue on the controller. Here is some example code:
this.PerformSegue("LoginSegue",this);
The controller that is loaded is the LoginController, and LoginSegue is a Segue that points to the HomeTabBarNavigator. While it is not perfect, the applications loaded the tabbar properly.
I used this stackoverlflow iOS question as the basis for my solution.
Is it possible to somehow override the login method of the Secure.java class of the Secure-Module in Play! Framework, so that another version of the login form is displayed?
In my case, i want to display a mobile version of the login-form if a mobile browser is detected.
I know i should not change the Secure.java class itself, but i don't really see any other solution to this problem.
As discussed in other posts you have the request in your Play! controller. So in this request you could ask which agent is trying to view your website:
String agentInfo = request.headers.get("user-agent");
The you can determine which template will be rendered for this agent:
if (agentType.isWhatEverHeIs) {
renderTemplate("Application\mobileTemplateForBadPractise.html");
} else {
render();
}
But what I would encourage you to do is responsive webdevelopment. Create your templates as smart as possible, let the template and css and javascript do this and keep your business logic in your controller.
You could use the Twitter Bootstrap to achieve this, but there are many more! Like Skeleton.
You even got the request object inside your templates so that you can optionally render things in your template (or not) based on the agent.
Even simpler, simply create/override the secure/login.html template and use responsive design : media queries. No need to change the controller or check agent or whatever.
