It will be good to share a sample pom of what you're using. For instance if you clone aem-wcm-core-components repo and execute mvn clean install on the bundles/core folder it generates all folders as you expect, and eventually under site folder you will also see coverage html files. May be you can c...

Well in its original form of HTL its not possible, as HTL is server side and ajax call is client side. However, similar to what @Saravanan_Dharmaraj suggested, you can probably have a default markup with hidden attributes to be sent to client side in the initial load, and once ajax call is executed,...

I am assuming, that you are looking for the capability in SPA based pages. Here is what I can recommend. Just like what @partyush you will need a custom service to eventually do this. However, to invoke the custom link checker, for model.json calls, just add a sling filter that processes all model.j...

My guess, but can't be so sure. Please check. The triggers section in your replication agent. If the modify flag is tuned on or checked may be turning it off might resolve the issue. Thanks

Previously provided responses are going to help you build pages probably in the way you desire. But I can share a bit of my expedience here. See technically you are migrating from a different source. As mentioned in the 1st reply it's crucial you have a migration strategy. It's not about just the ap...

Sorry but I don't get a clear understanding of how these components are being rendered. Are you using custom web elements? However for your usecase I may use style system and define the css that is based of parent container rather than handling in Java script. However if you are using the background...

The whole idea of content fragments is to store static content that can be Ui agnostic so it can be delivered to various channels. Now the issue with your requirement is validating user access which again forces you to right a custom layer that will call the cf api and then filters based on your req...

Do you have a dispatcher that's probably blocking model.json requests? Can you find if thats the case. And as a last resort compare infinity.json on en node in author and publisher.

Yes. Recently one of my team mates used this to conditionally include a clientlib using defer and doesn't require any customization.
