Replication in AEM is a process of publishing pages content from Author Instance to Process Instance. It is also used to filter content from Dispatcher cache. It transfers user data from the publish environment to the user environment.
If the AEM replication fails, the action must be taken according to the situation. If the replications are getting queued in the replication agent queues, it can be checked by accessing the ‘/etc/replication/agents.author.html’. Click replication agents for analysis of the situation.
In reverse replication, the content is transferred from the publisher environment to the authoring environment. It is used to replicate data related to profile details of the user and posts in the website’s forum.
The listener property in AEM for a component is used to define what happens before or after an action on the component. This is added by using the “cq:listeners” node with a node type of “cq:EditListenersConfig”. The listener property can also be added to any widget in AEM. In order to add a listener to that widget you just need to add a node that is called “listeners” with a type of “nt:unstructured”. Then you just need to add child nodes to the “listeners” node that are events of that widget. You can find a list of events for each widget by searching CQ Widget API documentation.
In AEM these xtypes are widgets that used in the creation of components. AEM comes with a bunch of widgets that are available out of the box. You can also create and define your own xtype to be used in AEM. An example of an xytpe is when you are creating your dialog for your component, and you want the author to be able to enter text, you would add a “cq:Widget” that has an xtype property of “textfield”.
