When i select Generate Application Module class and click OK, The AMImpl.java class is generated without any code. what might be the reason for this?
It's because all the code is in the base class.
What do you expect to be in the class?
When you define to create the class, you can choose what will be created (all based on the time you create the class).
Then all methods you write will end up in this class and can be exposed to the client.
Use is described here.
Per the docs:
The base classes of the ADF Business Components framework may be
extended to incorporate custom code with all types of components in
the framework and to extend the ADF Business Components framework
behavior.
When used without customization, your business component is completely defined by its XML document and it will be fully functional
without custom Java code or even a Java class file for the component.
If you have no need to extend the built-in functionality of a
component in ADF Business Components, and no need to write any custom
code to handle its built-in events, you can use the component in this
XML-only fashion. However, when you do extend base classes of the ADF
Business Components framework, you can still work with XML documents
in JDeveloper.
Once you have created framework extension classes, any new business component you create can be based on your customized
framework class instead of the base one. And, you can always update
the definitions of existing components to use the new framework
extension class as well.
Best practice is to create your own set of custom framework extension classes so you have hook points for creating common code for your custom ADF BC EOs and VOs

I am automating tests using selenium webdriver using test ng framework. Here am trying to implement POI and factory Design pattern.
Basically am testing on two websites (Which differs in GUI interface)which has login pages
Login Name and Password and login button but the challenging part is webelements has different ID in both the websites.
HOw to write a generic methods for this?
For locators i have a an enum class where i take the instance of each value and call it in the method.
As id is different than for sure you need to define both elements. There is no such solution for it.
In your testcase you can implement a check which defines that you on which environment and accordingly it will pass the element
My team is creating the administration panel of a CMS using React, Typescript, TSX and Webpack. Each page of the administration panel has been created as a React component, and each page contains many other child components (one for each section).
The CMS distribution currently includes a bundled version of the javascript needed to run the web app, but not the original TSX files.
Now, we would like to make it possible to the developers using our CMS to extend the web app by
1) Injecting additional sections into the UI using a "slot-fill" approach
2) Possibly even overriding the existing sections rendering a different component in the same place.
<div>
<SidebarComponent />
<Section1Component />
<Section2Component />
// How to inject a possible PluginComponent here?
</div>
From the research we've conducted so far, there seem to be no "official" way to do this, so I'm wondering what would be the best approach in this case.
I am facing the same issue where I need a component from a plugin to interact with a component from another plugin with a hook system. I have a created a small codesanbox with the same approach adapted to your need.
Basically the approach is to create a injectedComponents.js at the root of your plugin that specifies in which plugin and area your component needs to be injected.
Here is ademo
single-spa has some good options in order to achieve this.
Please see if it can be help for you.

I am late to this but
Just create a utility class with registry function, and register each component to the registry (just dictionary of key value pair, where key is a constant and Value is the component). T
Then when you display a component in your base app, get it from the registry using a key. Then once you publish this whole base app as package ( make sure to export the utility registry). A user can register a component with the same name and override the default component.
For communication between totally independant components, you can use and EventEmitter
In my angular application, back-end users can create custom templates. Those custom templates need to be loaded in the angular application at specific positions. I have a custom directive which gets templates
( based on the routes) from the CMS and inject it to my angular application. If I put it into the innerHTML the components will not get rendered correctly. I need componentFactoryResolver and compiler to properly show the components.
The above solution does not work with AOT compilation. Is there any other way I can achieve the same and make use of AOT? Is server side rendering is only solution to this?
Angular doesn't encourage using Compiler to create dynamic template.
Could/would/will code using COMPILER_PROVIDERS be supported by AOT?
But maybe in future it will be possible with without shipping the compiler because new View Engine open new capabilities.
Properties
the generated code relies on very few internals.
we can make the API public and stable
users could ship the generated factory files on npm
this makes calls to ngc in applications faster as it does not need
to compile the code of libraries like Ionic any more.
users could implement their own ViewEngine
this way we can drop the Renderer abstraction, as we already have an indirection via the ViewEngine
users could create templates programmatically during runtime
without shipping the compiler
eg for a dynamic form / ....
we might want to provide a builder for this that calculates indices correctly and can already be used in tests
we could create a new kind of directive that transforms a ViewDefinition, e.g. wraps elements into new ones, ... (similar to the compile in Angular 1).
needs some helpers that maps indices from new to original indices

I am currently using the Backbone philosophy which involves dust.js for template style. Recently I came across AngularJS, which extends the HTML syntax with custom elements and attributes.
Cons of Backbone+dust.js environment:
Upgrading components is time consuming.
Module specification and identification is not easy.
If I move my functionality to AngularJS will it be helpful or does it feel the same?
Can anyone explain to me what the major differences among these two libs are, as they seem similar to some extent?
dust.js is purely a templating module. So, it allows the combination of json with a template to deliver html output.
Angular.js is client side framework that allows binding of logic to variables defined in a template (your page).
So, with dust.js you are responsible for deciding when to run the json through the template. Typically you feed in the json on the server (or client) and ask it to render the results.
With angular.js when the model (the json) changes the framework re-renders as appropriate. Triggers for that change could be user actions (such as filling a form in) or it could be due to loading some fresh json from a service.
Typically you would use angular.js if you want a single page JS app (think gmail). dust.js is perhaps more akin to a traditional approach with multi pages with content driven by passing in json.
You could even use the both of them in tandem - server side rendering using dust.js with dynamic client side logic in angular.js.
I was using a simple WCF service with silverlight but I wanted to validate data with annotations and I didn't want to write a whole new layer in silverlight project. So I decided to switch to using a DomainService, created through generating code in the silverlight project.
Now comes the trouble. I have a parent class and about 10 derived classes. Through WCF, I was able to just use the base class. Now I am trying to use a DomainService with the base class decorated with the KnownType attribute. The problem is now those attributes get replicated in silverlight client and a compilation error is thrown. Anybody know how to use DomainService with inheritance? I want to deliver only the information from the base class.
I don't completely follow what your problem is, but this is a great tutorial on how to use Domain Services in Silverlight, and the example includes an abstract base class for all entities, similar to what I think you're doing.
