How to create a AEM Search component.
I need the logic and code for the following parts.
Search component HTL code for Input and Results.
Model code for searching the "fulltext" using QueryBuilder.
Clientlib (if any).
These are all readily available as part of the open-source Core Components Search:
Component HTL/Sightly script
Sling Model interface and implementation
Servlet for loading results
Client-side JS and CSS/LESS code

I am rather new to ASP.NET MVC5. I know server side controls are not working directly in MVC, but there will be some way by which we will get similar controls in MVC5 for rapid development. Can you suggest me how can I find such controls? Can you list out all such mostly used common controls for MVC5?
Thanks in advance.
There's no concept of a "control" in MVC. There's various things that function similar to Web Form controls, but it depends on what you're trying to do.
HTML Helpers are similar in that you essentially call a function that returns rendered HTML. You can extend HtmlHelper to add your own.
Child actions function as a sort of separate request within the context of the main request. They accept parameters like an action, can do all the backend stuff an action can do (query database, etc.) and return a view rendered based on a model, like a normal view.
A partial view, in general, can function as a control as it allows you to insert a snippet of HTML somewhere.
Editor templates and display templates can be used in conjunction with Html.EditorFor and Html.DisplayFor, respectively to render a form field or some sort of HTML display for a particular property on your model.
I know we should use unit tests for our reactjs components. But what I also want, is some way to manually test our components in isolation. Because we are working on small sprints in which we must deliver some finished component before having the page that first uses that component. And I want to see that full component really working (i.e. test integration with css and sub-components).
So to start with, I would like to see that new component rendered in black page that doesn't require that component directly, but to take that component name/path from a query-string parameter. And then I plan to add to that page some generic component configuration (e.g. a textbox with json representing the props to pass to that component).
The first problem I'm facing now is about how to configure webpack, webpack-dev-middleware, or webpack-dev-server to be able to load a component passed by parameter.
Anyone know how to that? Or a better way to handle this?
I would try something like this:
Set up an entry point that uses require.context.
Invoke require within that context based on your querystring. You should have you React component now. Render that through React.
In order to generate the test controls I would include the meta within the component using JSON Schema. The form controls could be then generated using some form generator such as plexus-form or tcomb-form.
I have been through this documentation on ADF declarative component but not still not clear on the intent of such a component . I want to know what is the use of this guy and what are the scenarios where such a component could become useful ? Is this related to ui:composition in JSF2.0 ?
af:declarativeComponent defines a dynamic declarative component and is used in ADF as a light weight form of encapsulating some UI logic. Think of it not as a template, but as a component that one can define without declaring a tag name (as for regular declarative components) and much lighter then a task-flow. When used you can pass parameters to such a component (including methods parameters since ADF 11.1.2). Such a component can also have a backing bean which executes in backing bean scope, so that if you have multiple instances of this component in a page you will have as many corresponding instances of the backing bean at the run-time, so the logic executed there will not interfere from one instance to another.
ADF Declarative component is composite component created using predefined ADF Faces components. It can be included in a packaged jar file and can be included in any ADF Pages or Page Fragments as a reusable component.
Example: Create a declarative component for user login
User Name [ af:InputText ]
Passwork [ af:InputText ]
SubmitButton
This component can be included in the login page in any application
I' working on a library control for Xpages and need some help in creating.
I would create a control which reads a configuration file and creates controls in a table, controls like Editboxes, checkboxgroups and so on.
so and now to my questions:
could I initiate controls from the Exlib or must I implement them all by my self?
if I could use them from the Exlib could anyone explain me how?
I hope its clear what i mean if not please ask me for further informations.
When creating your own components, if you're closely replicating some behavior that is already in an extension library component, I highly recommend you extend that component and just add what's needed to accommodate your different functionality. This makes things much easier and you don't have to code around every little scenario that the component might be placed in.
But, if you are developing a component that is nothing like any of the extension library or core components then just ensure your component extends UIComponent or UIComponentBase. If going this route, you'll also need to create your own renderer which extends Renderer. This is what will build the on-screen representation of your component. Again, if there's already something in the core components or extension library components that closely mimics what you need then make your renderer extend that renderer. Also, don't forget to include the renderer definition in the faces-config file and the component definition in the xsp-config file or your component won't work.
As for initiating controls from the extlib.... I assume you mean can you inject them onto the page at runtime. If so the answer is absolutely yes. To add an input text field to the page where there is a container (i.e. panel, div, span, whatever) with an ID of "someContainer"
XspInputText input = new XspInputText();
input.setValue("someValue");
input.setId("someID");
UIComponent container = FacesContext.getCurrentInstance().getViewRoot().findComponent("someContainer");
container.getChildren().add(input);
To see the api for all of the core and extension library components take a look at the XPages Controls Documentation. For a more complete tutorial on creating your own components take a look at my blog for creating a custom component inside an nsf, the steps are pretty much the same for putting them into a library:
Part 1,
Part 2 and there is an example database in the Part 2 post.
How to extend the functionality of Richfaces components for example Data table with custom header and sorting techniques. i have seen extended data table but did not get much information from it. Please point me to an example if at it is available.
Thanks

Well, you can extend a JSF component with the regular java extension (extends). You will have to extend a number of classes, depending on the exact component:
UIComponentName/HtmlComponentName
HtmlComponentNameRenderer
ComponentNameTag
and you might need to register the renderer in faces-config.xml.
You can take a look at this thread, or google for "Extend JSF component" or "Create custom JSF component".
